I didn't know this board, so i checked and its a stepper driver unit. So, I can't help you. I've worked with camsoft a lot, but only with servos and galil card. My guess is not many have used steppers with camsoft.
P.S. I just checked, there's a very nice manual on this card in my help directory called stepper board.rtf. looks to me like the home inputs aren't connected.
P.P.S. i just read it some. The home switches are NC so you could just jumper each of the four switches to ground for testing
