sundial77,
Don't want to sound harsh,
YOU will need to spend the time looking for or asking the manufacturer for info on the controller.
May luck out and someone else will have the info. Till then, do some leg work and surely someone will be able to help you. If you hit a dead end on that, then take detailed pictures of the controller internals and then maybe someone can
give some guidence.Thats the hard way as you will need to trace things out.
