Help connecting servos to breakout board Mach3

[Agathon]

I'm beginning to wish I hadn't started this...

I have Omron R88D-U servo drivers and a R88D-U motor to test it all with. I've connected the motor and the encoder. However, I can't get into the servo driver software as for some reason the OMNUC interface software and the Yaskawa software doesn't like my USB-RS232 port and won't connect with the servo drive.

Anyway, I'd like to try running the servo driver from my BOB using the current settings, but I can't get to the bottom of what I need to connect. It would seem logical that I only need four or five wires to give the driver an enable signal and step and direction pulse, but I'm buggered if I can see exactly what I need to do

Attached are the pin-outs from the driver interface plug.
