Hello Lucas

Your PM settings won't allow me contact you directly. Just wondering if you ever got any further with your YAPSC - type converter.

There"s some further testing needed, I will publish schematics etc.. when everything works as it should .

This design is compatible with Max's PCB (connector pinout) but has some changes and improvements, well I consider these as improvements :-)

- a real RS422 receiver is used for the encoder: 26LS32, capable of differential and single ended encoders and with proper line termination for high speed.
- works on a single supply: 8 to 24Vdc, + and - 12V are generated by a DC-DC converter.
- encoder can be connected with a DB9 or screw terminals.
- stp/dir/enable inputs have optocouplers and can be connected using a PMinmo style flatcable or screw terminals
- The progkey is compatible, this or Max's version can be used on both designs

I have 9 PCB"s left now for some beta-testers.

One thing might change: the drive error input and Yapsc error output, this is very basic now and might need improvement to support more models of analog drives.

Please send me a PM if you"re interested.
