Troubleshooting

Mainboard:

I. Analog inputs are "jittering": Sometimes analog inputs are jittering all the time without any reason. Help: Use jumper / bridges on every analog input, which isn't in use. Put the jumper on every pin#1 & pin#2.

""Key64-Daughterboard:"" II. Ghost-effect of inputs: If you have connected only one switch (e.g. toggle, rotary, momentary, etc.) to your Key64-Daughterboard, and you use it (e.g. turn it to ON), and there are more connections showing as ON, this would be called Ghost-effect. It can also happen if there are more switches than only one attached . Ghosting will show closed electrical circuits - even if they aren't existent or not closed. Help: 1. Check the soldering points on your Motherboard. Sometimes two soldering points are connected by accident. 2. Check your flatcables from Motherboard to Key64-Daughterboard. Sometimes there are two or more wires connected by accident. Often happens if the connector isn't is attached 100% correctly. 3. Check your flatcables at Key64-Daughterboard. Sometimes there are two or more wires connected by accident. Often happens if the connector isn't is attached 100% correctly. 4. Check your common and other connections at Key64-Daughterboard. Crosscheck with the wiring diagram on this page. Are the common pins attached to the correct corresponding connection-pins? Are your connection pins all attached correctly?
