Remotec ZRC-90 - discovered but nothing else

@stephack - thanks for your reply. You’re of course right about the model being ZRC.

I’d really like to make these work. I’ve tried more than 20 times with more than one (I had ordered 4) and always the same result.

If others got them to work I would love nothing more than learning how to get that done.

@mike.maxwell - can you help?
