Steve and the gang,

Thanks for all the help with the parallel port to driver interface connections. Now that I have a harness built for the computer parallel port interface, I am ready to wire the motors to the drivers. I have two unipolar six wire steppers p/n 57BYGH405A and two CW260C drivers. The color code on the stepper motor is A=RED, C=GRN, B=YEL, D=BLU and the coil center taps are black and white. The drivers have six connections on the power side labeled: <DC70V/VCC, GND, A+, A-, B+, B-. Which wires on the driver go to which wires on the stepper motor.

Thanks DiBo
