1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project suc-cessful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-
40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the
tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and en-ables you to make good connections. When solder rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use
any flux or grease. • A diagonal cutter to trim excess wires. To avoid injury
when cutting excess leads, hold the lead so they can-not fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place. • Small blade and phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is re-
quired, or might be handy 1.2 Assembly Hints : þ Make sure the skill level matches your experience, to avoid disappointments. þ Follow the instructions carefully. Read and understand the entire step before
you perform each operation. þ Perform the assembly in the correct order as stated in this manual þ Position all parts on the PCB (Printed Circuit Board) as shown on the drawings. þ Values on the circuit diagram are subject to changes. þ Values in this assembly guide are correct* þ Use the check-boxes to mark your progress. þ Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :
Mount the component against the PCB surface and carefully solder the leads
Make sure the solder joints are cone-shaped and shiny
Trim excess leads as close as possible to the solder joint

12. OPERATION
A) Control section (P8023S): Both PCBs are connected to each other by means of two wires, VTX+ and VTX-. They supply power to the control board and carry the data signal. This signal contains information regarding the status of the 10 inputs. Filtering and regulating of the power supply is performed by VR2, together with C15, C12, C13 and C14, which also suppress possible oscillation of the voltage regulator. The micro controller continuously monitors the status of the inputs, and switches T2 according to a custom developed serial protocol. This allows a current to flow in the VTX wires. LD12 also lights allowing you to check the operation of the sys-tem. B) Receiver section (P8023R): The receiver end also contains a power supply section. Diodes D1 to D4 rectify the incoming power. Voltage regulator VR1 and the surrounding capacitors make sure the control part receives a regulated 10V. From this 10V, R12, ZD1 and C8 derive 5V DC to supply the microcontroller. The actual receiving part consists of D6, D7, R14, R15 and T1. The current variations in the VTX-lines cause a voltage drop over R15, which is filtered by C3 and amplified by T1, before it is fed to the micro controller. Reception is indicated by LD11. The microcontroller analyses the serial signal, and puts the corresponding outputs high or low. Because the microcontroller cannot sink large currents, we added IC2 and IC3, which provide open collector outputs. Hook-up and testing: Connect both PCB’s P8023S and P8023R according to fig. 1. Both push buttons and switches can be used to control the inputs. Keep the distance between the switches or push buttons and the circuit as short as possible. If the circuit is used in a noisy environment (e.g. proximity of electric motors, transformers, ….) or if the distance between the switches and the circuit exceeds 1m (3"), a shielded cable must be used to connect the switches. The shield must be connected to the ‘COM’ terminal. If the K8023 circuit is powered from an AC source, then you will need an external DC source to power the relays, and the ‘+ Vext’ terminal must be connected. (fig 1) This kit can be used with several other Velleman Kits. Fig 2…5 show some hook-up examples.
