Intro How to Extend yout USB using UTPThis is my second Instructables This time Im gonna tell everyone how to extend your USB using UTP Why do you need to do so Because the USB extender in shopsonly around 15 meters Its very short if you need 50 meters for a USB WiFi antenna on your roof So I share to you people this technique
PS I will be making the Instructables of the Indonesias style of USB WiFi antenna The picture is below
Step 1 Gather your partsYou need(1)USB Cable(2)UTP Cable(3)Small PVC Pipe(4)Rubber tape(5)thermofit heatshrink
Step 2 The making of Part 1Open the UTP and USB cable Put the small PVC pipe in the UTP cable Put the thermofit in the USB cable Then connect it like this
white orange amp orange to redwhite amp green to whitegreen to greenand the rest to black
Remeber to solder it

anjumraza says Nov 26 2010 1248 AM REPLYi was worried after puchasing evo usb for net surfingsignals were very week i made the utp wire and connectors and found that the signals were very higheven a distance of 24 feet from computer to usbthx instructable i loved that
instructables_nando says Aug 25 2010 835 PM REPLYI did this with a cheap 25ft UTP cable from e-bay and it worked perfect I try with USB and web-cam there was no lag or anything like it while watching orcapturing video webcam to backyard I have fear phobia
rohit123 says Apr 26 2010 133 AM REPLYi want to keep my web cam 50meter awaypurpose of keeping web cam far is monitoring of my small brother from my roomdoes it works properly
ambo says Aug 26 2008 217 PM REPLYhelloi already follow your procedure for the usb extension using UTPbut i cannot make it detect as a 20 usbcoz ill use it with a 20 compatibledevicesPlease let me know if you have an answer for thisthank you
Derin says Sep 2 2008 852 AM REPLYin my experienceUSB 20 will talk USB 11 as welland USB 11 can connect to USB 20 hosts

sintar says Mar 31 2010 759 PM REPLYin my observations a shielded 2 x 20g 2 x 28g good quality cable will do about 25 feet but it all depends on the voltage drop or resistance of the wiretest for example 20ft wire with my multi meter i read 11 to 12 ohms on the shield but 1 ohm on the vcc and gnd and 15 ohms on the data lines butyou dont use those values to calculate your voltage drop first you need to subtract your test leads from the resistance since all wire has resistanceon my meter they have a 6 ohm reading keep in mind im not using a cheap 10 dollar meter here so that leaves me with 6 ohms on vcc and ground and 9 ohm on the data lines but we really dont need to worry about the data to much unless your going over 35 40 feet using ohms law E = I R Ebeing voltage drop I being current (5 A or 500 ma) and r being resistive load (in ohms) the formula works out to be 45 volts so knowing that usbwont work below 44 say 45 to be safe then finding out my computers 5 volt line runs at 513 v so 513 - 45 = 468 volts after voltage drop and thatsat max load and most devices dont use the full 500ma theres some room for error now as long as the signals are clean at the far end then it shouldwork now if you lose to much voltage over your run of cable and you can place a power supply regulated +5v and MAKE SURE TO TEST THIScloser to the end of your cable and just disconnect the +5v from the computer now for those longer distance runs you need to use a larger conductordata pair single wire for each no doubling up here or you can get some nasty interference now if you have enough power larger conductor data wiresand you still have a dirty data problem try using some ferrite rings on both ends they really do help with EMI traveling over wires sorry for thecrudeness and no punctuation but i hope this helps somebody
bayucandra says Jan 19 2010 529 AM REPLYThis man doesnt included the detail way of put the IC and the input power if some body need more clear picture try to visithttpwwwdheglengoridqe3p=136 I dont know is the man who wrote this instructables article and the man who wrote the article at the link i gave issame person But the link i gave have more clear description The problem only that my link is in Indonesian language but dont worry it has clear picture justto see
Squink81 says Sep 2 2009 444 AM REPLYHi there I already made up a 10M USB 20 cable and I thick I remember it works ok from the computer with a webcam But I want a longer USB cable to usethe webcam to take photographs about the house and outside Can I use this telephone cable It has 4 wires and is used for the telephone but I am not sureif it is the same as the UTP cable
dombeef says Jan 3 2010 834 AM REPLYYou need 5 for ground wire
Squink81 says Jan 4 2010 216 PM REPLYThank you
egomez18 says Jan 3 2010 821 AM REPLYIt works perfectly Later I will give details of how that works best with the same UTP cable Thank you very much for your idea
zeefar says Mar 8 2009 213 PM REPLYWhen I connect the flash drive to the connector through the set up of USB over UTP to PC the computer does not read the data from my flash drive devicewhy is that
Dexterdoom says Aug 27 2009 705 AM REPLYMost USB devices wont work with an extension that long without the aid of a USB powered hub They use 5V provided by the computer and the voltagedrop over more than about 20 feet is enough to create a USB device not recognized by the PC I Use webcams for security on my home and have touse a powered hub or it wont pick the cams up Try it
k_man93 says Oct 18 2009 911 AM REPLY what if you use a USB y cable that draws power from 2 ports therefore doubling the power am i correct on this
charlie millionaire says Apr 10 2009 805 PM REPLYYour cord must be too long then
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
spudgunster says Jul 24 2009 614 PM REPLYThe USB works in a way that theoretically limits any cable length to 16 feet If I remember correctly that includes the powered repeater cables too I thinkthey do have some usb to cat5 converter boxes but thats way different from this instructable This instructable will not work its not magic with UTPs youwont get much more than 15 thats my guess
theviper0308 says Jun 12 2009 358 AM REPLYi was tried using 15meter utp cablebut not works coz the power is drop down
cyberjoejoe says Jun 1 2009 945 PM REPLYive tried this a year ago works great on my epson c59 printer
matbh says May 27 2009 1038 PM REPLYI think u should use a powered usb hub to amplify the signal computer usb ports (specially usb front ports they r 11 standards) cant read the data froma flash drive or something similar maybe a hard drive Im not sure
cksiamcn says May 4 2009 830 AM REPLYits work for flash drive but i use with usb wireless 20 not work how can i do next
forkber says May 16 2009 1019 AM REPLYIt work on a 7 meters (23 feet) CAT6 cable use a twisted pair for the D+ D- USB and another for the power (black and red on Usb cable) I use it with aHD multimedia player at full speed (USB 2) Tanks
rian elmirez says Apr 24 2009 736 PM REPLYi m from indonesia amp i have try itso its good
angtrop says May 9 2009 1019 AM REPLYmas Rian saya mohon petunjuknya bagaimana membuat perpanjangan kabel usb karena setelah saya membeli kabel perpanjangan yang 5 meterternyata setelah saya masukkan ke komputer tidak terdeteksisaya mohon petunjuknya untuk menyelesaikan masalah terserbut kemudian apa sajayang harus saya lakukan karena saya membutuhkan kabel sepanjang 50 meter
Sk8erCk4Life says Apr 22 2009 648 PM REPLYwhat is UTP cable and where can I get it
sameheddy says Apr 19 2009 1143 AM REPLYThe wires of the Utb cable can you draw it more detalied to be connected the rightway
j21a2t89 says Mar 23 2009 1154 AM REPLYJust a quick point you could use a usb hub (with all the plastic stripped off) to regenerate the signal So using the utp as well you could extend the cabletheorectically to any length You would need to remove the power socket on the hub and have a powerful enough 5v source hmm i should create aninstructable
Danicek says Mar 1 2009 200 AM REPLYA have an idea put something like MAX3003 to the middle of long extension cable This IC is a level translator between different voltage logic levels but ispossible to connect it as fast bidirectional repeater with automatic direction control In theory input signal which is degraded by passing long distanceshould be shaped almost back to the original and sent to the output Order for this ICs is already placed for another project in my job so I will test itOfcourse it will work ONLY for UBS 11 because bitrate limitation
sagewifi says Jul 18 2008 1223 PM REPLYIs there a reason you bound those colors Is red and blank on the USB - power and ground I guess you want more copper (2 or 3 UTP wires) for powerand ground than the signal wires I did something similar with DIY PoE to my roof Thanks- Great for USB webcams
CrudeBuster says Sep 7 2008 1248 PM REPLYI suggest instead of using only one wire use instead a pair for each usb pin this will lessen the impedance and grant good stability in connections Iknow better I did a 50-feet cable like that testing hard and exhaustively
Danicek says Feb 20 2009 446 AM REPLYUsing 2 Pairs for supply voltage is good idea But do not use it for signal path
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
CrudeBuster says Feb 26 2009 614 AM REPLYUm why not If twisted pair is good for Ethernet TX RX why wouldnt be good for USB D+D-
Danicek says Feb 26 2009 1000 AM REPLYFor DC supply you need lownest possible resistance in path So it is good idea use one pait as +5V and other pair as GND AC charakteristicis not so importantOn other hand we can almost omit currents in signal path at least for USB because there is no termination For signal path parameters isimportant AC point of view And in this case bigger volume of cable will make bigger condensator to chargedischarge -gt bigger looses onhigher frequenciesSo use 1 and half pair for +5V another 15 pair for gnd and 1 pair for D+ and D-
BTW for 100Mbit ethernet1 pair = TX+ TX-1 pair = RX+ RX-2 pairs unused (used for 1Gbit ethernet)
CrudeBuster says Feb 26 2009 207 PM REPLYBut as the theoretical limit of USB data signal wiring is 5 meters were trading loss in high frequency for stability lessening theimpedance Well Ill test your suggestion anyway because Im having problems with different USB controllers some do accept theextension over 10m others dont get even 4m
CrudeBuster says Feb 28 2009 1215 PM REPLYThe alternate wiring using 1 pair and a half for +5 and GND functioned very well kudos for you for the tip Danicek
Even in my EEEPc where the pair wiring didnt worked after 2m 10m using the alternate worked like a breeze with my mouse andmp4 player as well as the Encore USB dongle
I used this particular wiring colorsOrange pair + WhiteLight Blue = +5Maroon pair + Dark Blue = GNDDark Green = +DWhiteLight Green = -D
The +5 measured 505 with the mouse working the alternate wiring kept the loss really down
00JAMIEJOHNSON00 says Feb 27 2009 308 PM REPLYTHIS WORKED PERFECTLY WITH MY BELKIN F5D8053 N BAND USB WIFI ADAPTOR AND OVER 35FT OF CAT 5 CABLE I DID HAVE TO PLUG ITINTO MY USB 10 HUB AND NOT THE USB 20 PORTS ON MY DESKTOP TO GET IT TO WORK RIGHT I HAVENT NOTICED ANY SIGNAL LOSSAND IT SAVED ME AT LEAST $50 IN CABLES AND USB REPEATERS THANKS A LOT
Spajky [-Spikey] says Nov 3 2008 1151 PM REPLYmaybe someone should check also my solution to the problem using two thin coaxial linescables sorry posts are not in english but everything needed ison schematics marked to reproduce the solution Here
Danicek says Feb 20 2009 443 AM REPLYUSB data signals are diferential They are making a pair Idea split them into 2 coaxial cables is not good This will rapidly incrase parasitic capacitance Ithink you will get better results by using good quality twisted pair cable Idea with separate on place power suply is good This will help you compensatevoltage drop on longer line
Spajky [-Spikey] says Feb 21 2009 1138 AM REPLYYes I know they are differential (to the gnd) amp practically still are in my schematics The differential lines are shielded but NOT terminated to theground on the line
That my suggested coax is 75ohm impedance 55pFm 55ohmkm DC per inner wire amp 10dB attenuation at 100MHz A tipical UTP cable has100ohm impedance 50pFm 100ohmkm DC per inner wire amp 20dB attenuation at 100MHz With lesser impedance (one line Usb to the gnd iseven less) capacitance matters less with thicker wires there is less voltage drop amp if you use a multiple of half wavelenght of that coax (basic Usbclock = 48MHz) you can extend the range even more since that mirrors the impedance from one to another end of the line
Well I admit that using 2 coax-es is less practical than using a single cable like UTP for longer lines and popping on it a higher voltage tocompensate voltage drop but the signal will degenerate even before than using 2 coax-es so its suggestible to use a hub after 20m of lenghtanyway
Yes using UTP cable up to 15 m of lenght is easier
fishought says Dec 3 2008 101 AM REPLYthe circuit doesnt work its only a 5 volts supply
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
Danicek says Feb 20 2009 430 AM REPLYYes it is bad designed 5V supply1 What is purpose in of +9V battery (supply) and D12 Never put large electrolytic capacitor (100uF and more) to the output of 78xx At the time of turn on capacitor is empty and for some time can drawmore than 1A of current Onchip protection of 78xx will shutdown the stabilizer and restarts This will produce oscilations in output voltage It is better putsome small tantal capacitor about 33uF to the output in parallel with ceramic 100nF decoupling capacitor as close as possible to 78xx Another 100nFcapacitor should be connected to the input of 78xxAnother thing Do not forget fit suitable heatsink In full load (standart USB 500mA) there will be 35W power loss ( (12V - 5V) 05A )
trohner says Jul 5 2008 1208 AM REPLYI dont know how usb cables look inside the only difference i see possible is that we have a twisted pair here But what are they twisted with Is it with theground wire In a usb connection we have ground 5V Rx and Tx data lines Since Rx and Tx are not differential signal pairs as in Ethernet the twisting hasa somewhat limited impact on the signal quality This is only my theoretical judgement i didnt try it The circuit shown in the intro is just a 5V power supplyThis may help with usb devices using much power like harddrives but it wont enhance signal quality You can get away with some usb extension but i dontknow to what extent I once hooked a 5m extension to a 3m wifi stick holder and had no problems This was usb 11 by the way But Hunag seems to use itso why not give it a try if you need it It wont cost much
Danicek says Feb 20 2009 401 AM REPLYYou are not right There is no Tx and Rx wire in USB Wires are +5V Gnd D+ and D- D+ and D- ARE differential signals and twisting is important
francote6 says Dec 30 2008 530 AM REPLYIt Works Although I only needed 14Mtshellip did not work until I connected the cable UTP CAT3 (Is possible that is better with the CAT6) directly to the card of theWebcam to omit the ferrite nucleus through which the cable original passes (In my case the image was not deteriorated) Perhaps confucioacuten with the orderof the connection of cables has appeared They must beWhiteorange + orange to redwhite to whitegreen to greenthe rest to black
balachanderraidu says Oct 7 2008 841 AM REPLYI tried it out with tho UTP wires connected at da same time but still it doesnt work is there any way out im using USB20 port
Sk8erCk4Life says Dec 21 2008 121 PM REPLYI soldered the wires like it said to but put extra shrink tube on it and I used old ehernet cord
Sk8erCk4Life says Dec 21 2008 1239 PM REPLYWhatever I took a used ethernet cord and did what it said to do and it works
leBeau says Jul 28 2008 1225 AM REPLYCan anybody help me I have bought an cat5e utp cable and and usb extension cord I soldered green to green orangewhite amp orange to red andgreenwhite to white The remaining cables (bluewhite blue blackwhite black) I soldered to black I also insulated them My usb port in the computer usedusb 20 Both the usb and the utp had uncoloured (that is to say they were bare) copper wires I soldered those together and insulated them aswell Should Ihave soldered the bare copper wires to black aswell Should I set my pc to usb 1 Should I not connect some wires to the black usb wire Please help
Sk8erCk4Life says Nov 25 2008 748 PM REPLYHow do you set your pc to usb 1 and 2
Sk8erCk4Life says Nov 6 2008 429 PM REPLYDo you have to use all the wire in the UTP cord or can you just hook up four of them since there is only four wires in a USB cable and match the same colorson the opposite side and can you use round phone wire with the six wires in it insted of UTP
Sk8erCk4Life says Oct 31 2008 754 PM REPLYCan you take the phone line that has six wires in it and take and use only four of them and solder it and hook it up the same way

forkber says May 16 2009 1019 AM REPLYIt work on a 7 meters (23 feet) CAT6 cable use a twisted pair for the D+ D- USB and another for the power (black and red on Usb cable) I use it with aHD multimedia player at full speed (USB 2) Tanks
rian elmirez says Apr 24 2009 736 PM REPLYi m from indonesia amp i have try itso its good
angtrop says May 9 2009 1019 AM REPLYmas Rian saya mohon petunjuknya bagaimana membuat perpanjangan kabel usb karena setelah saya membeli kabel perpanjangan yang 5 meterternyata setelah saya masukkan ke komputer tidak terdeteksisaya mohon petunjuknya untuk menyelesaikan masalah terserbut kemudian apa sajayang harus saya lakukan karena saya membutuhkan kabel sepanjang 50 meter
Sk8erCk4Life says Apr 22 2009 648 PM REPLYwhat is UTP cable and where can I get it
sameheddy says Apr 19 2009 1143 AM REPLYThe wires of the Utb cable can you draw it more detalied to be connected the rightway
j21a2t89 says Mar 23 2009 1154 AM REPLYJust a quick point you could use a usb hub (with all the plastic stripped off) to regenerate the signal So using the utp as well you could extend the cabletheorectically to any length You would need to remove the power socket on the hub and have a powerful enough 5v source hmm i should create aninstructable
Danicek says Mar 1 2009 200 AM REPLYA have an idea put something like MAX3003 to the middle of long extension cable This IC is a level translator between different voltage logic levels but ispossible to connect it as fast bidirectional repeater with automatic direction control In theory input signal which is degraded by passing long distanceshould be shaped almost back to the original and sent to the output Order for this ICs is already placed for another project in my job so I will test itOfcourse it will work ONLY for UBS 11 because bitrate limitation
sagewifi says Jul 18 2008 1223 PM REPLYIs there a reason you bound those colors Is red and blank on the USB - power and ground I guess you want more copper (2 or 3 UTP wires) for powerand ground than the signal wires I did something similar with DIY PoE to my roof Thanks- Great for USB webcams
CrudeBuster says Sep 7 2008 1248 PM REPLYI suggest instead of using only one wire use instead a pair for each usb pin this will lessen the impedance and grant good stability in connections Iknow better I did a 50-feet cable like that testing hard and exhaustively
Danicek says Feb 20 2009 446 AM REPLYUsing 2 Pairs for supply voltage is good idea But do not use it for signal path
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
CrudeBuster says Feb 26 2009 614 AM REPLYUm why not If twisted pair is good for Ethernet TX RX why wouldnt be good for USB D+D-
Danicek says Feb 26 2009 1000 AM REPLYFor DC supply you need lownest possible resistance in path So it is good idea use one pait as +5V and other pair as GND AC charakteristicis not so importantOn other hand we can almost omit currents in signal path at least for USB because there is no termination For signal path parameters isimportant AC point of view And in this case bigger volume of cable will make bigger condensator to chargedischarge -gt bigger looses onhigher frequenciesSo use 1 and half pair for +5V another 15 pair for gnd and 1 pair for D+ and D-
BTW for 100Mbit ethernet1 pair = TX+ TX-1 pair = RX+ RX-2 pairs unused (used for 1Gbit ethernet)
CrudeBuster says Feb 26 2009 207 PM REPLYBut as the theoretical limit of USB data signal wiring is 5 meters were trading loss in high frequency for stability lessening theimpedance Well Ill test your suggestion anyway because Im having problems with different USB controllers some do accept theextension over 10m others dont get even 4m
CrudeBuster says Feb 28 2009 1215 PM REPLYThe alternate wiring using 1 pair and a half for +5 and GND functioned very well kudos for you for the tip Danicek
Even in my EEEPc where the pair wiring didnt worked after 2m 10m using the alternate worked like a breeze with my mouse andmp4 player as well as the Encore USB dongle
I used this particular wiring colorsOrange pair + WhiteLight Blue = +5Maroon pair + Dark Blue = GNDDark Green = +DWhiteLight Green = -D
The +5 measured 505 with the mouse working the alternate wiring kept the loss really down
00JAMIEJOHNSON00 says Feb 27 2009 308 PM REPLYTHIS WORKED PERFECTLY WITH MY BELKIN F5D8053 N BAND USB WIFI ADAPTOR AND OVER 35FT OF CAT 5 CABLE I DID HAVE TO PLUG ITINTO MY USB 10 HUB AND NOT THE USB 20 PORTS ON MY DESKTOP TO GET IT TO WORK RIGHT I HAVENT NOTICED ANY SIGNAL LOSSAND IT SAVED ME AT LEAST $50 IN CABLES AND USB REPEATERS THANKS A LOT
Spajky [-Spikey] says Nov 3 2008 1151 PM REPLYmaybe someone should check also my solution to the problem using two thin coaxial linescables sorry posts are not in english but everything needed ison schematics marked to reproduce the solution Here
Danicek says Feb 20 2009 443 AM REPLYUSB data signals are diferential They are making a pair Idea split them into 2 coaxial cables is not good This will rapidly incrase parasitic capacitance Ithink you will get better results by using good quality twisted pair cable Idea with separate on place power suply is good This will help you compensatevoltage drop on longer line
Spajky [-Spikey] says Feb 21 2009 1138 AM REPLYYes I know they are differential (to the gnd) amp practically still are in my schematics The differential lines are shielded but NOT terminated to theground on the line
That my suggested coax is 75ohm impedance 55pFm 55ohmkm DC per inner wire amp 10dB attenuation at 100MHz A tipical UTP cable has100ohm impedance 50pFm 100ohmkm DC per inner wire amp 20dB attenuation at 100MHz With lesser impedance (one line Usb to the gnd iseven less) capacitance matters less with thicker wires there is less voltage drop amp if you use a multiple of half wavelenght of that coax (basic Usbclock = 48MHz) you can extend the range even more since that mirrors the impedance from one to another end of the line
Well I admit that using 2 coax-es is less practical than using a single cable like UTP for longer lines and popping on it a higher voltage tocompensate voltage drop but the signal will degenerate even before than using 2 coax-es so its suggestible to use a hub after 20m of lenghtanyway
Yes using UTP cable up to 15 m of lenght is easier
fishought says Dec 3 2008 101 AM REPLYthe circuit doesnt work its only a 5 volts supply
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
Danicek says Feb 20 2009 430 AM REPLYYes it is bad designed 5V supply1 What is purpose in of +9V battery (supply) and D12 Never put large electrolytic capacitor (100uF and more) to the output of 78xx At the time of turn on capacitor is empty and for some time can drawmore than 1A of current Onchip protection of 78xx will shutdown the stabilizer and restarts This will produce oscilations in output voltage It is better putsome small tantal capacitor about 33uF to the output in parallel with ceramic 100nF decoupling capacitor as close as possible to 78xx Another 100nFcapacitor should be connected to the input of 78xxAnother thing Do not forget fit suitable heatsink In full load (standart USB 500mA) there will be 35W power loss ( (12V - 5V) 05A )
trohner says Jul 5 2008 1208 AM REPLYI dont know how usb cables look inside the only difference i see possible is that we have a twisted pair here But what are they twisted with Is it with theground wire In a usb connection we have ground 5V Rx and Tx data lines Since Rx and Tx are not differential signal pairs as in Ethernet the twisting hasa somewhat limited impact on the signal quality This is only my theoretical judgement i didnt try it The circuit shown in the intro is just a 5V power supplyThis may help with usb devices using much power like harddrives but it wont enhance signal quality You can get away with some usb extension but i dontknow to what extent I once hooked a 5m extension to a 3m wifi stick holder and had no problems This was usb 11 by the way But Hunag seems to use itso why not give it a try if you need it It wont cost much
Danicek says Feb 20 2009 401 AM REPLYYou are not right There is no Tx and Rx wire in USB Wires are +5V Gnd D+ and D- D+ and D- ARE differential signals and twisting is important
francote6 says Dec 30 2008 530 AM REPLYIt Works Although I only needed 14Mtshellip did not work until I connected the cable UTP CAT3 (Is possible that is better with the CAT6) directly to the card of theWebcam to omit the ferrite nucleus through which the cable original passes (In my case the image was not deteriorated) Perhaps confucioacuten with the orderof the connection of cables has appeared They must beWhiteorange + orange to redwhite to whitegreen to greenthe rest to black
balachanderraidu says Oct 7 2008 841 AM REPLYI tried it out with tho UTP wires connected at da same time but still it doesnt work is there any way out im using USB20 port
Sk8erCk4Life says Dec 21 2008 121 PM REPLYI soldered the wires like it said to but put extra shrink tube on it and I used old ehernet cord
Sk8erCk4Life says Dec 21 2008 1239 PM REPLYWhatever I took a used ethernet cord and did what it said to do and it works
leBeau says Jul 28 2008 1225 AM REPLYCan anybody help me I have bought an cat5e utp cable and and usb extension cord I soldered green to green orangewhite amp orange to red andgreenwhite to white The remaining cables (bluewhite blue blackwhite black) I soldered to black I also insulated them My usb port in the computer usedusb 20 Both the usb and the utp had uncoloured (that is to say they were bare) copper wires I soldered those together and insulated them aswell Should Ihave soldered the bare copper wires to black aswell Should I set my pc to usb 1 Should I not connect some wires to the black usb wire Please help
Sk8erCk4Life says Nov 25 2008 748 PM REPLYHow do you set your pc to usb 1 and 2
Sk8erCk4Life says Nov 6 2008 429 PM REPLYDo you have to use all the wire in the UTP cord or can you just hook up four of them since there is only four wires in a USB cable and match the same colorson the opposite side and can you use round phone wire with the six wires in it insted of UTP
Sk8erCk4Life says Oct 31 2008 754 PM REPLYCan you take the phone line that has six wires in it and take and use only four of them and solder it and hook it up the same way

sintar says Mar 31 2010 759 PM REPLYin my observations a shielded 2 x 20g 2 x 28g good quality cable will do about 25 feet but it all depends on the voltage drop or resistance of the wiretest for example 20ft wire with my multi meter i read 11 to 12 ohms on the shield but 1 ohm on the vcc and gnd and 15 ohms on the data lines butyou dont use those values to calculate your voltage drop first you need to subtract your test leads from the resistance since all wire has resistanceon my meter they have a 6 ohm reading keep in mind im not using a cheap 10 dollar meter here so that leaves me with 6 ohms on vcc and ground and 9 ohm on the data lines but we really dont need to worry about the data to much unless your going over 35 40 feet using ohms law E = I R Ebeing voltage drop I being current (5 A or 500 ma) and r being resistive load (in ohms) the formula works out to be 45 volts so knowing that usbwont work below 44 say 45 to be safe then finding out my computers 5 volt line runs at 513 v so 513 - 45 = 468 volts after voltage drop and thatsat max load and most devices dont use the full 500ma theres some room for error now as long as the signals are clean at the far end then it shouldwork now if you lose to much voltage over your run of cable and you can place a power supply regulated +5v and MAKE SURE TO TEST THIScloser to the end of your cable and just disconnect the +5v from the computer now for those longer distance runs you need to use a larger conductordata pair single wire for each no doubling up here or you can get some nasty interference now if you have enough power larger conductor data wiresand you still have a dirty data problem try using some ferrite rings on both ends they really do help with EMI traveling over wires sorry for thecrudeness and no punctuation but i hope this helps somebody

Squink81 says Sep 2 2009 444 AM REPLYHi there I already made up a 10M USB 20 cable and I thick I remember it works ok from the computer with a webcam But I want a longer USB cable to usethe webcam to take photographs about the house and outside Can I use this telephone cable It has 4 wires and is used for the telephone but I am not sureif it is the same as the UTP cable
dombeef says Jan 3 2010 834 AM REPLYYou need 5 for ground wire
Squink81 says Jan 4 2010 216 PM REPLYThank you
egomez18 says Jan 3 2010 821 AM REPLYIt works perfectly Later I will give details of how that works best with the same UTP cable Thank you very much for your idea
zeefar says Mar 8 2009 213 PM REPLYWhen I connect the flash drive to the connector through the set up of USB over UTP to PC the computer does not read the data from my flash drive devicewhy is that
Dexterdoom says Aug 27 2009 705 AM REPLYMost USB devices wont work with an extension that long without the aid of a USB powered hub They use 5V provided by the computer and the voltagedrop over more than about 20 feet is enough to create a USB device not recognized by the PC I Use webcams for security on my home and have touse a powered hub or it wont pick the cams up Try it
k_man93 says Oct 18 2009 911 AM REPLY what if you use a USB y cable that draws power from 2 ports therefore doubling the power am i correct on this

spudgunster says Jul 24 2009 614 PM REPLYThe USB works in a way that theoretically limits any cable length to 16 feet If I remember correctly that includes the powered repeater cables too I thinkthey do have some usb to cat5 converter boxes but thats way different from this instructable This instructable will not work its not magic with UTPs youwont get much more than 15 thats my guess

sintar says Mar 31 2010 759 PM REPLYin my observations a shielded 2 x 20g 2 x 28g good quality cable will do about 25 feet but it all depends on the voltage drop or resistance of the wiretest for example 20ft wire with my multi meter i read 11 to 12 ohms on the shield but 1 ohm on the vcc and gnd and 15 ohms on the data lines butyou dont use those values to calculate your voltage drop first you need to subtract your test leads from the resistance since all wire has resistanceon my meter they have a 6 ohm reading keep in mind im not using a cheap 10 dollar meter here so that leaves me with 6 ohms on vcc and ground and 9 ohm on the data lines but we really dont need to worry about the data to much unless your going over 35 40 feet using ohms law E = I R Ebeing voltage drop I being current (5 A or 500 ma) and r being resistive load (in ohms) the formula works out to be 45 volts so knowing that usbwont work below 44 say 45 to be safe then finding out my computers 5 volt line runs at 513 v so 513 - 45 = 468 volts after voltage drop and thatsat max load and most devices dont use the full 500ma theres some room for error now as long as the signals are clean at the far end then it shouldwork now if you lose to much voltage over your run of cable and you can place a power supply regulated +5v and MAKE SURE TO TEST THIScloser to the end of your cable and just disconnect the +5v from the computer now for those longer distance runs you need to use a larger conductordata pair single wire for each no doubling up here or you can get some nasty interference now if you have enough power larger conductor data wiresand you still have a dirty data problem try using some ferrite rings on both ends they really do help with EMI traveling over wires sorry for thecrudeness and no punctuation but i hope this helps somebody

Squink81 says Sep 2 2009 444 AM REPLYHi there I already made up a 10M USB 20 cable and I thick I remember it works ok from the computer with a webcam But I want a longer USB cable to usethe webcam to take photographs about the house and outside Can I use this telephone cable It has 4 wires and is used for the telephone but I am not sureif it is the same as the UTP cable
dombeef says Jan 3 2010 834 AM REPLYYou need 5 for ground wire
Squink81 says Jan 4 2010 216 PM REPLYThank you
egomez18 says Jan 3 2010 821 AM REPLYIt works perfectly Later I will give details of how that works best with the same UTP cable Thank you very much for your idea
zeefar says Mar 8 2009 213 PM REPLYWhen I connect the flash drive to the connector through the set up of USB over UTP to PC the computer does not read the data from my flash drive devicewhy is that
Dexterdoom says Aug 27 2009 705 AM REPLYMost USB devices wont work with an extension that long without the aid of a USB powered hub They use 5V provided by the computer and the voltagedrop over more than about 20 feet is enough to create a USB device not recognized by the PC I Use webcams for security on my home and have touse a powered hub or it wont pick the cams up Try it
k_man93 says Oct 18 2009 911 AM REPLY what if you use a USB y cable that draws power from 2 ports therefore doubling the power am i correct on this
charlie millionaire says Apr 10 2009 805 PM REPLYYour cord must be too long then

spudgunster says Jul 24 2009 614 PM REPLYThe USB works in a way that theoretically limits any cable length to 16 feet If I remember correctly that includes the powered repeater cables too I thinkthey do have some usb to cat5 converter boxes but thats way different from this instructable This instructable will not work its not magic with UTPs youwont get much more than 15 thats my guess
theviper0308 says Jun 12 2009 358 AM REPLYi was tried using 15meter utp cablebut not works coz the power is drop down

Sk8erCk4Life says Apr 22 2009 648 PM REPLYwhat is UTP cable and where can I get it
sameheddy says Apr 19 2009 1143 AM REPLYThe wires of the Utb cable can you draw it more detalied to be connected the rightway
j21a2t89 says Mar 23 2009 1154 AM REPLYJust a quick point you could use a usb hub (with all the plastic stripped off) to regenerate the signal So using the utp as well you could extend the cabletheorectically to any length You would need to remove the power socket on the hub and have a powerful enough 5v source hmm i should create aninstructable
Danicek says Mar 1 2009 200 AM REPLYA have an idea put something like MAX3003 to the middle of long extension cable This IC is a level translator between different voltage logic levels but ispossible to connect it as fast bidirectional repeater with automatic direction control In theory input signal which is degraded by passing long distanceshould be shaped almost back to the original and sent to the output Order for this ICs is already placed for another project in my job so I will test itOfcourse it will work ONLY for UBS 11 because bitrate limitation
sagewifi says Jul 18 2008 1223 PM REPLYIs there a reason you bound those colors Is red and blank on the USB - power and ground I guess you want more copper (2 or 3 UTP wires) for powerand ground than the signal wires I did something similar with DIY PoE to my roof Thanks- Great for USB webcams
CrudeBuster says Sep 7 2008 1248 PM REPLYI suggest instead of using only one wire use instead a pair for each usb pin this will lessen the impedance and grant good stability in connections Iknow better I did a 50-feet cable like that testing hard and exhaustively
Danicek says Feb 20 2009 446 AM REPLYUsing 2 Pairs for supply voltage is good idea But do not use it for signal path
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
CrudeBuster says Feb 26 2009 614 AM REPLYUm why not If twisted pair is good for Ethernet TX RX why wouldnt be good for USB D+D-
Danicek says Feb 26 2009 1000 AM REPLYFor DC supply you need lownest possible resistance in path So it is good idea use one pait as +5V and other pair as GND AC charakteristicis not so importantOn other hand we can almost omit currents in signal path at least for USB because there is no termination For signal path parameters isimportant AC point of view And in this case bigger volume of cable will make bigger condensator to chargedischarge -gt bigger looses onhigher frequenciesSo use 1 and half pair for +5V another 15 pair for gnd and 1 pair for D+ and D-
BTW for 100Mbit ethernet1 pair = TX+ TX-1 pair = RX+ RX-2 pairs unused (used for 1Gbit ethernet)
CrudeBuster says Feb 26 2009 207 PM REPLYBut as the theoretical limit of USB data signal wiring is 5 meters were trading loss in high frequency for stability lessening theimpedance Well Ill test your suggestion anyway because Im having problems with different USB controllers some do accept theextension over 10m others dont get even 4m
CrudeBuster says Feb 28 2009 1215 PM REPLYThe alternate wiring using 1 pair and a half for +5 and GND functioned very well kudos for you for the tip Danicek
Even in my EEEPc where the pair wiring didnt worked after 2m 10m using the alternate worked like a breeze with my mouse andmp4 player as well as the Encore USB dongle
I used this particular wiring colorsOrange pair + WhiteLight Blue = +5Maroon pair + Dark Blue = GNDDark Green = +DWhiteLight Green = -D
The +5 measured 505 with the mouse working the alternate wiring kept the loss really down
00JAMIEJOHNSON00 says Feb 27 2009 308 PM REPLYTHIS WORKED PERFECTLY WITH MY BELKIN F5D8053 N BAND USB WIFI ADAPTOR AND OVER 35FT OF CAT 5 CABLE I DID HAVE TO PLUG ITINTO MY USB 10 HUB AND NOT THE USB 20 PORTS ON MY DESKTOP TO GET IT TO WORK RIGHT I HAVENT NOTICED ANY SIGNAL LOSSAND IT SAVED ME AT LEAST $50 IN CABLES AND USB REPEATERS THANKS A LOT
Spajky [-Spikey] says Nov 3 2008 1151 PM REPLYmaybe someone should check also my solution to the problem using two thin coaxial linescables sorry posts are not in english but everything needed ison schematics marked to reproduce the solution Here
Danicek says Feb 20 2009 443 AM REPLYUSB data signals are diferential They are making a pair Idea split them into 2 coaxial cables is not good This will rapidly incrase parasitic capacitance Ithink you will get better results by using good quality twisted pair cable Idea with separate on place power suply is good This will help you compensatevoltage drop on longer line
Spajky [-Spikey] says Feb 21 2009 1138 AM REPLYYes I know they are differential (to the gnd) amp practically still are in my schematics The differential lines are shielded but NOT terminated to theground on the line
That my suggested coax is 75ohm impedance 55pFm 55ohmkm DC per inner wire amp 10dB attenuation at 100MHz A tipical UTP cable has100ohm impedance 50pFm 100ohmkm DC per inner wire amp 20dB attenuation at 100MHz With lesser impedance (one line Usb to the gnd iseven less) capacitance matters less with thicker wires there is less voltage drop amp if you use a multiple of half wavelenght of that coax (basic Usbclock = 48MHz) you can extend the range even more since that mirrors the impedance from one to another end of the line
Well I admit that using 2 coax-es is less practical than using a single cable like UTP for longer lines and popping on it a higher voltage tocompensate voltage drop but the signal will degenerate even before than using 2 coax-es so its suggestible to use a hub after 20m of lenghtanyway
Yes using UTP cable up to 15 m of lenght is easier

Danicek says Feb 20 2009 430 AM REPLYYes it is bad designed 5V supply1 What is purpose in of +9V battery (supply) and D12 Never put large electrolytic capacitor (100uF and more) to the output of 78xx At the time of turn on capacitor is empty and for some time can drawmore than 1A of current Onchip protection of 78xx will shutdown the stabilizer and restarts This will produce oscilations in output voltage It is better putsome small tantal capacitor about 33uF to the output in parallel with ceramic 100nF decoupling capacitor as close as possible to 78xx Another 100nFcapacitor should be connected to the input of 78xxAnother thing Do not forget fit suitable heatsink In full load (standart USB 500mA) there will be 35W power loss ( (12V - 5V) 05A )
trohner says Jul 5 2008 1208 AM REPLYI dont know how usb cables look inside the only difference i see possible is that we have a twisted pair here But what are they twisted with Is it with theground wire In a usb connection we have ground 5V Rx and Tx data lines Since Rx and Tx are not differential signal pairs as in Ethernet the twisting hasa somewhat limited impact on the signal quality This is only my theoretical judgement i didnt try it The circuit shown in the intro is just a 5V power supplyThis may help with usb devices using much power like harddrives but it wont enhance signal quality You can get away with some usb extension but i dontknow to what extent I once hooked a 5m extension to a 3m wifi stick holder and had no problems This was usb 11 by the way But Hunag seems to use itso why not give it a try if you need it It wont cost much
Danicek says Feb 20 2009 401 AM REPLYYou are not right There is no Tx and Rx wire in USB Wires are +5V Gnd D+ and D- D+ and D- ARE differential signals and twisting is important
francote6 says Dec 30 2008 530 AM REPLYIt Works Although I only needed 14Mtshellip did not work until I connected the cable UTP CAT3 (Is possible that is better with the CAT6) directly to the card of theWebcam to omit the ferrite nucleus through which the cable original passes (In my case the image was not deteriorated) Perhaps confucioacuten with the orderof the connection of cables has appeared They must beWhiteorange + orange to redwhite to whitegreen to greenthe rest to black

Sk8erCk4Life says Nov 25 2008 748 PM REPLYHow do you set your pc to usb 1 and 2
Sk8erCk4Life says Nov 6 2008 429 PM REPLYDo you have to use all the wire in the UTP cord or can you just hook up four of them since there is only four wires in a USB cable and match the same colorson the opposite side and can you use round phone wire with the six wires in it insted of UTP
Sk8erCk4Life says Oct 31 2008 754 PM REPLYCan you take the phone line that has six wires in it and take and use only four of them and solder it and hook it up the same way

Sk8erCk4Life says Nov 25 2008 748 PM REPLYHow do you set your pc to usb 1 and 2
Sk8erCk4Life says Nov 6 2008 429 PM REPLYDo you have to use all the wire in the UTP cord or can you just hook up four of them since there is only four wires in a USB cable and match the same colorson the opposite side and can you use round phone wire with the six wires in it insted of UTP
Sk8erCk4Life says Oct 31 2008 754 PM REPLYCan you take the phone line that has six wires in it and take and use only four of them and solder it and hook it up the same way

spudgunster says Jul 24 2009 614 PM REPLYThe USB works in a way that theoretically limits any cable length to 16 feet If I remember correctly that includes the powered repeater cables too I thinkthey do have some usb to cat5 converter boxes but thats way different from this instructable This instructable will not work its not magic with UTPs youwont get much more than 15 thats my guess
theviper0308 says Jun 12 2009 358 AM REPLYi was tried using 15meter utp cablebut not works coz the power is drop down
cyberjoejoe says Jun 1 2009 945 PM REPLYive tried this a year ago works great on my epson c59 printer
matbh says May 27 2009 1038 PM REPLYI think u should use a powered usb hub to amplify the signal computer usb ports (specially usb front ports they r 11 standards) cant read the data froma flash drive or something similar maybe a hard drive Im not sure
cksiamcn says May 4 2009 830 AM REPLYits work for flash drive but i use with usb wireless 20 not work how can i do next
forkber says May 16 2009 1019 AM REPLYIt work on a 7 meters (23 feet) CAT6 cable use a twisted pair for the D+ D- USB and another for the power (black and red on Usb cable) I use it with aHD multimedia player at full speed (USB 2) Tanks
rian elmirez says Apr 24 2009 736 PM REPLYi m from indonesia amp i have try itso its good
angtrop says May 9 2009 1019 AM REPLYmas Rian saya mohon petunjuknya bagaimana membuat perpanjangan kabel usb karena setelah saya membeli kabel perpanjangan yang 5 meterternyata setelah saya masukkan ke komputer tidak terdeteksisaya mohon petunjuknya untuk menyelesaikan masalah terserbut kemudian apa sajayang harus saya lakukan karena saya membutuhkan kabel sepanjang 50 meter
Sk8erCk4Life says Apr 22 2009 648 PM REPLYwhat is UTP cable and where can I get it
sameheddy says Apr 19 2009 1143 AM REPLYThe wires of the Utb cable can you draw it more detalied to be connected the rightway
j21a2t89 says Mar 23 2009 1154 AM REPLYJust a quick point you could use a usb hub (with all the plastic stripped off) to regenerate the signal So using the utp as well you could extend the cabletheorectically to any length You would need to remove the power socket on the hub and have a powerful enough 5v source hmm i should create aninstructable
Danicek says Mar 1 2009 200 AM REPLYA have an idea put something like MAX3003 to the middle of long extension cable This IC is a level translator between different voltage logic levels but ispossible to connect it as fast bidirectional repeater with automatic direction control In theory input signal which is degraded by passing long distanceshould be shaped almost back to the original and sent to the output Order for this ICs is already placed for another project in my job so I will test itOfcourse it will work ONLY for UBS 11 because bitrate limitation
sagewifi says Jul 18 2008 1223 PM REPLYIs there a reason you bound those colors Is red and blank on the USB - power and ground I guess you want more copper (2 or 3 UTP wires) for powerand ground than the signal wires I did something similar with DIY PoE to my roof Thanks- Great for USB webcams
CrudeBuster says Sep 7 2008 1248 PM REPLYI suggest instead of using only one wire use instead a pair for each usb pin this will lessen the impedance and grant good stability in connections Iknow better I did a 50-feet cable like that testing hard and exhaustively
Danicek says Feb 20 2009 446 AM REPLYUsing 2 Pairs for supply voltage is good idea But do not use it for signal path
httpwwwinstructablescomidHow-to-Extend-yout-USB-using-UTP
CrudeBuster says Feb 26 2009 614 AM REPLYUm why not If twisted pair is good for Ethernet TX RX why wouldnt be good for USB D+D-
Danicek says Feb 26 2009 1000 AM REPLYFor DC supply you need lownest possible resistance in path So it is good idea use one pait as +5V and other pair as GND AC charakteristicis not so importantOn other hand we can almost omit currents in signal path at least for USB because there is no termination For signal path parameters isimportant AC point of view And in this case bigger volume of cable will make bigger condensator to chargedischarge -gt bigger looses onhigher frequenciesSo use 1 and half pair for +5V another 15 pair for gnd and 1 pair for D+ and D-
BTW for 100Mbit ethernet1 pair = TX+ TX-1 pair = RX+ RX-2 pairs unused (used for 1Gbit ethernet)
CrudeBuster says Feb 26 2009 207 PM REPLYBut as the theoretical limit of USB data signal wiring is 5 meters were trading loss in high frequency for stability lessening theimpedance Well Ill test your suggestion anyway because Im having problems with different USB controllers some do accept theextension over 10m others dont get even 4m
CrudeBuster says Feb 28 2009 1215 PM REPLYThe alternate wiring using 1 pair and a half for +5 and GND functioned very well kudos for you for the tip Danicek
Even in my EEEPc where the pair wiring didnt worked after 2m 10m using the alternate worked like a breeze with my mouse andmp4 player as well as the Encore USB dongle
I used this particular wiring colorsOrange pair + WhiteLight Blue = +5Maroon pair + Dark Blue = GNDDark Green = +DWhiteLight Green = -D
The +5 measured 505 with the mouse working the alternate wiring kept the loss really down
00JAMIEJOHNSON00 says Feb 27 2009 308 PM REPLYTHIS WORKED PERFECTLY WITH MY BELKIN F5D8053 N BAND USB WIFI ADAPTOR AND OVER 35FT OF CAT 5 CABLE I DID HAVE TO PLUG ITINTO MY USB 10 HUB AND NOT THE USB 20 PORTS ON MY DESKTOP TO GET IT TO WORK RIGHT I HAVENT NOTICED ANY SIGNAL LOSSAND IT SAVED ME AT LEAST $50 IN CABLES AND USB REPEATERS THANKS A LOT
Spajky [-Spikey] says Nov 3 2008 1151 PM REPLYmaybe someone should check also my solution to the problem using two thin coaxial linescables sorry posts are not in english but everything needed ison schematics marked to reproduce the solution Here
Danicek says Feb 20 2009 443 AM REPLYUSB data signals are diferential They are making a pair Idea split them into 2 coaxial cables is not good This will rapidly incrase parasitic capacitance Ithink you will get better results by using good quality twisted pair cable Idea with separate on place power suply is good This will help you compensatevoltage drop on longer line
Spajky [-Spikey] says Feb 21 2009 1138 AM REPLYYes I know they are differential (to the gnd) amp practically still are in my schematics The differential lines are shielded but NOT terminated to theground on the line
That my suggested coax is 75ohm impedance 55pFm 55ohmkm DC per inner wire amp 10dB attenuation at 100MHz A tipical UTP cable has100ohm impedance 50pFm 100ohmkm DC per inner wire amp 20dB attenuation at 100MHz With lesser impedance (one line Usb to the gnd iseven less) capacitance matters less with thicker wires there is less voltage drop amp if you use a multiple of half wavelenght of that coax (basic Usbclock = 48MHz) you can extend the range even more since that mirrors the impedance from one to another end of the line
Well I admit that using 2 coax-es is less practical than using a single cable like UTP for longer lines and popping on it a higher voltage tocompensate voltage drop but the signal will degenerate even before than using 2 coax-es so its suggestible to use a hub after 20m of lenghtanyway
Yes using UTP cable up to 15 m of lenght is easier

Danicek says Feb 20 2009 430 AM REPLYYes it is bad designed 5V supply1 What is purpose in of +9V battery (supply) and D12 Never put large electrolytic capacitor (100uF and more) to the output of 78xx At the time of turn on capacitor is empty and for some time can drawmore than 1A of current Onchip protection of 78xx will shutdown the stabilizer and restarts This will produce oscilations in output voltage It is better putsome small tantal capacitor about 33uF to the output in parallel with ceramic 100nF decoupling capacitor as close as possible to 78xx Another 100nFcapacitor should be connected to the input of 78xxAnother thing Do not forget fit suitable heatsink In full load (standart USB 500mA) there will be 35W power loss ( (12V - 5V) 05A )
trohner says Jul 5 2008 1208 AM REPLYI dont know how usb cables look inside the only difference i see possible is that we have a twisted pair here But what are they twisted with Is it with theground wire In a usb connection we have ground 5V Rx and Tx data lines Since Rx and Tx are not differential signal pairs as in Ethernet the twisting hasa somewhat limited impact on the signal quality This is only my theoretical judgement i didnt try it The circuit shown in the intro is just a 5V power supplyThis may help with usb devices using much power like harddrives but it wont enhance signal quality You can get away with some usb extension but i dontknow to what extent I once hooked a 5m extension to a 3m wifi stick holder and had no problems This was usb 11 by the way But Hunag seems to use itso why not give it a try if you need it It wont cost much
Danicek says Feb 20 2009 401 AM REPLYYou are not right There is no Tx and Rx wire in USB Wires are +5V Gnd D+ and D- D+ and D- ARE differential signals and twisting is important
francote6 says Dec 30 2008 530 AM REPLYIt Works Although I only needed 14Mtshellip did not work until I connected the cable UTP CAT3 (Is possible that is better with the CAT6) directly to the card of theWebcam to omit the ferrite nucleus through which the cable original passes (In my case the image was not deteriorated) Perhaps confucioacuten with the orderof the connection of cables has appeared They must beWhiteorange + orange to redwhite to whitegreen to greenthe rest to black
