Mach2 & Rutex relay board.

Up till now I have been turning my spindle on and off manually.

I havent connected the spindle to the Rutex relay board yet.
I have tried to get the relays to respond to Mach2 input but cant hear them click in or out. I have tried to configure the relay board to respond to Mach2's input but have had not luck.
In the Rutex pdf concerning the relay board it says that I need to use pin 14 of the printer cable and use port C./1 . What does C./1 mean.

Has any one else successfully enabled spindle control using the relay board?

Not yet, I have my board somewhere on the way to Sweden right now...

There is a document describing the schematic at the rutex web page, at http://www.rutex.com/pdf/R990IO.pdf where you hopefully can find the answer. Any possibilty that some shortcut jumper is left somewhere after tuning the drives that maybe takes over a parallel port pin?

Cheers,
Sven
