Folks,
I have three brand-new Allen-Bradley servo drives and a Bob Campbell Breakout board. My plan is to configure the system and operate it with MACH3. My question is about interface the step and direction outputs from the breakout board to the servo drives. All the AB ultra drives can accept step and direction input, but each has two inputs (Step + and Step-) and (Dir+ and Dir-). I can't figure out how to connect this to the breakout board, and I am really afraid of burning up either the controller or the servo drives.
Can anyone help?
Thanks for any advice,
Paul Vogt,

Two of the drives are Ultra 100 and one is an Ultra 3000
