      What commands can I send via serial to the CM750?

      Send remote commands to your CM750 from a PLC or host computer using these supported control instructions.

      Why use serial commands?

      They allow real-time control of the printer without human interaction:

      • Start/stop printing

      • Switch messages

      • Query printer status

      • Log events or alerts

      Supported command examples

      Command Function
      PRINT Start print mode
      STOP Stop printing
      MSG 002 Load message number 002
      STATUS Request printer status
      VERSION Returns firmware version
      CLRFAULT Clears active fault
       

      How to send commands

      1. Connect via RS232 or RS485

      2. Match serial settings between devices

      3. Send ASCII command via PLC or PC terminal (9600 baud default)

      4. Monitor return message for confirmation or fault
