Thanks for the detail! Just what I need

So you are wiring this direct to the serial port on the emepg's wiring harness ?

I wonder if the 50Hz supply here in the UK will effect the pulse times from the Seeburg?

And also I think I have a 200 selection unit, so I guess I may have to learn how to do all this stuff myself anyway

Thanks for the help so far.

Cheers

Cris.
