Crestron DigitalMedia Infrastructure Guide

IntroductionThis guide is intended to explain the dierent inrastructure options and require-

ments or DigitalMedia installations. DM is an extremely versatile AV distribu-

tion system, capable o switching and transporting virtually any video signal type

over a mixed copper/fber inrastructure. In addition to digital and analog HD audio

and video, DM also distributes Ethernet, USB-HID and control signals.

Whether youre a seasoned DMC-D or this is your introduction to DM, this guide

will help you determine what inrastructure is right or your project.

Infrastructure ChoicesThanks to modular input and output cards, DM systems are able to oer our dierent ways o transporting signals

over a choice o CAT5-type or multimode fber cable. These include DM 8G+ (DM over a single CAT5e or better

UTP or STP), Original DM CAT (DM over proprietary STP plus CAT5e and DMNet), DM 8G Fiber (DM over simplex

multimode fber), and Original DM Fiber (DM over duplex multimode fber).

Comparing Copper and Fiber Transports

DigitalMedia uses CAT5-based and/or multimode fber cabling to transport its signals.

Copper InfrastructureWhen the term copper is used in a DigitalMedia context, it reers to CAT5-type wire. With DM, you are able to

choose wire based on your application.

Beore choosing wire, evaluate which version o DM copper product youll be installing.

DM 8G+ is an upgrade to DM 8G technology which enables the use of

standard unshielded CAT5e or better cable. DM 8G+ is a firmware upgrade

and does not require any hardware changes. All existing DM 8G product

can be upgraded to DM 8G+ through a simple firmware package update.

This table illustrates the max distance a DM signal can run between endpoints and switchers. Dis-

tances over original DM technology are aected by resolution, whereas DM 8G+ can support each

resolution up to 330 eet (100 meters) between endpoints.

NOTE:An endpoint reers to any device, other than a switcher, to which DM terminates (transmitter,

receiver, repeater).

Some high noise (EMI) environments may require shielded CAT5e or DM-CBL-8G for optimum performance.

Note: Refer to product spec sheets to verify each devices capabilities. The DM-TX1-1G and DM-RX1-1G have distance limitations not noted in this chart.

DM 8G+ Performance over Copper

DM 8G+ Technology Minimizes Errors without Compression

DM 8G+ transmits high resolution digital signals over unshielded CAT5e (UTP) with minimal errors. DM 8G+ tech-

nology maintains signal integrity over UTP without using compression, making it easy to upgrade existing QM, PVID

and other analog distribution systems while delivering the highest quality HD video and audio, along with Ethernet,

USB-HID and control.

DM 8G+ Best Practices

Unshielded CAT5e is approved or use with DM 8G+.

Shielded cable is advantageous only i it is terminated with shielded connectors.

Not every shielded connector is created equal. DM-8G-CONN is a ully shielded (and highly recommended

or DM 8G+ applications) RJ45 connector.

Shielded Connectors and Patch Cables!

To maintain the wire shield throughout the entire cable run, be sure to use ully shielded connectors. The wire

shield is rendered practically useless i it is not carried through the connector. Crestron DM-CONN and DM-8G-

CONN are ully shielded or use with DigitalMedia. Also, i youre using patch points, be sure to carry the shield

through ALL connecting points. These include wall plate, patch panels and patch cables.

DM-CONN DM-8G-CONN

DigitalMedia 8G Cable Facts

DM 8G cable is a shielded twisted pair CAT5e that is certified up to 350 MHz with more operational margin and

overhead than any other CAT5e. DM 8G cable is the highest grade data cable that can be used for networking

and communications where you would normally use shielded CAT5e or better cabling.

DM 8G cable is the only cable on the market that is pre-certified to reliably carry the full DM 8G bandwidth,

despite environmental interference, and is supported by the Crestron performance guarantee.

Every run of DM 8G cable off of the production line gets put through rigorous Crestron testing to certify that it can

handle the complete bandwidth spectrum from 0 to 350 MHz, and that it is immune to environmental interfer-

ence.

DM 8G cable exceeds all requirements of CAT5e data grade cable. As such, it is appropriate for use in computer

networks, or other AV distribution systems where CAT5e is supported. We also recommend DM 8G cable for use

with Sonnex, Crestron Home (CH) audio balun connections (CEN-IDOCV) and any other applications that require

CAT5e.

any resolution. Because o the abundant bandwidth o fber, video resolution does not aect transmis-

sion distance.

DM 3D Facts

Most DM devices are ready to send and receive 3D video.

3D does not require bandwidth beyond that o a 1080p signal.

Consult individual spec sheets or detailed compatibility with 3D.

Fiber Termination and Patching

Original DM and DM 8G fber can be patched through a panel, wall plate or similar point. The ollowing guidelines

must be ollowed when doing so.

Original DM and DM 8G Fiber Patching Guidelines

Any number o patch points may be used as long as the entire fber loss does not exceed 4 dB.

Any type o fber connector may be used in patches, as long as the fber that terminates to the DM device

uses SC connectors.

Reer to Crestron Doc. 4565 Cable Certifcationor inormation on how to test or optical loss.

Original DM Fiber Wall Plate DM 8G Fiber Wall Plate

MP-WP186 MP-WP187-S

Fiber Facts

OM3 or OM4 usually have an AQUA jacket.

OM3/OM4 implies core/cladding diameter is 50/125m.

SC connectors are most common or inside-plant telecom, but recently LCs (not compatible)

are becoming more popular due to their smaller size.

Intermediate patch panels and connections can use other types o connectors i necessary.
