Hi all,

I have the easson DRO system. I would like to use the encoders outputs as an inputs to my PC's parallel port.
I couldn't find any document that describes the DB-9 connectors pinout or any other informatiom about electrical compatibility (all I know that it is a TTL compatible).

Does anyone here have a pinout diagram?
Do I need to add an electrical convertor?

Thanks in advance,
Zvika
