8 Input programmable messageboard
with LCD & serial interface
Features :
Add an LCD display to any low-tech application and make it look high-te ch ! Replace up to 9 indicators or lamps by one single backlit LC D. Recall messages simply by pressing a button. Inputs accept dry contacts, open collectors and logic levels . No programming skills required ! Store up to 9 sixteen-character messages in non-volatile E EPROM memor y . 4 operating modes :
1) Display the status of all inputs simult aneously .
2) Display all active inputs.
3) Display active input with highest priority .
4) Display text messages in a ‘tickertape’-fashi on.
A default message can be entered and is display ed when no inputs are active. Messages can be transferred to the K8045 from any PC or terminal. Free message transfer software and source code for the K8045 is availabl e
from www.velleman.be
Wireless data transfer between PC/terminal and K 8045 is possible with op-
tional RX/TX433 modules.
1 on-board pushbutton available for y our application.

1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. 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 enables 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 cannot 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 required, or might
be handy
1.2 Assembly Hints :
Make sure the skill level matches your experience, to avoid disappointments. Follow the instructions carefully. Read and understand the entire step before
you perform each operation.
Perform the assembly in the correct order as stated in this manual Position all parts on the PCB (Printed Circuit Board) as shown on the draw-
ings.
Values on the circuit diagram are subject to changes. Values in this assembly guide are correct* Use the check-boxes to mark your progress. 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 :
1- Mount the component against the PCB surface
and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the sol­der joint
AXIAL COMPONENTS ARE TAPED IN
THE CORRECT MOUNTING SEQUENCE !
REMOVE THEM FROM THE TAPE ONE AT A TIME !
