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?
