Hi Vlad, you are clearly a better electronics expert than I am so perhaps you can help.

I received my cheap eBay CHP-86B panel from eBay today and have all the pushbuttons and lights working. However I am not sure how the encoders work. Here is a picture. Do you have any thoughts?

They seem to be connected to the PCB on the bottom with 8 pins. Inside there is some sort of wheel, which passes between the black components on the board I guess blocking a type of signal passing between them?

Update: I managed to find the manufacturer and emailed them who said that it is most like this component. This looks promising, Vlad no?

If I can power the IR LEDs on the one side, then the other side should give SimVim the normal encoder signal it needs..... I think?

I was thinking the same thing expect it’s potentially less work if I can get what’s there working. They are lovely and smooth as they don’t “click”. This is my plan to test.... if it doesn’t work I’ll just use a regular encoder.

You can just try to do this I.e. when the LED activates the phototransistor, it should short the pin to GND.

Just for the record I did get this working with SimVim!
Good to know, congrats!
What encoder type is suitable for it (that you set in the "Input Options" menu of the plugin)?
Vlad
Whatever the default was just worked.
