Generating CW /- CCW /- for step motor drive through NI USB-6212

[chithanhvn]

Dear Madame/Sir,

I'm working with a FASTECH step motor drive. I want to generate CW+/- and CCW+/- signals  for this drive. 
I want to ask you how to connect CW+/- and CCW+/- wires to USB 6212 ports.

Thank you advance!
