Setup Procedure

  1. Controller: The OpenCM 9.04 micro-controller is seated within the OpenCM EXP485 expansion board. The OpenCM 9.04 has been flashed and configured to run a 'serial tosser' upon power-up. All 3.3V TTL UART serial communication arriving from the PC (via FTDI USB-to-Serial board) is transcribed to a half duplex TTL (3-pin) or to a RS485 half duplex serial protocol and forwarded on to the motors. Likewise, transcription is performed in the reverse direction as well.
  1. Connect (Controller-to-FTDI USB-to-Serial):
  2. Connect (FTDI USB-to-Serial-to-PC):
  3. Connect Power:
  4. Connect (Controller-to-Motor(s)):
