    This eliminates the high frequency components of the noise generating a fast changing signal. Outputs 1, 14, 16 and 17 (Port 1 and 2) and outputs 2-9 (port 1). All those pins are directly wired to the C25 output terminals. User’s Manual Page 2...

  • Page 5: Powering The Board

    This board is designed to get its power from the Smooth Stepper. The Smooth Stepper has jumpers next to the IDC26 connector on which the C25 connects to that need to be closed in order to send +5vdc to pin 26 of each IDC26 connector to power the C25.
