Setting up the MP72 with IBM RS-485

Setting up the MP72 with IBM RS-485

Connect and configure the MP72 with an IBM RS-485 host.
  1. Attach the modular connector of the IBM RS-485 interface cable to the POS interface port on the MP72.
  2. Connect the other end of the IBM RS-485 interface cable to the appropriate port on the host (typically Port 9).
    Older POS systems and/or some retailers require use of the external power supply PWR-BGA12V50W0WW.
  3. After the unit powers up, select the port address by scanning the appropriate barcode in the MP72 Scanner Scale Barcode Programming Guide.
  4. For MP72 configurations with a scale, scan the appropriate scale port address (IBM Scale Port Addresses).
  5. To modify other parameter options, scan the appropriate barcodes in the MP72 Scanner Scale Barcode Programming Guide.
    The only required configurations are the port addresses (IBM RS-485 port address and a scale port address for scale configurations) and type directives. The IBM system typically controls other MP72 parameters.
    To prevent the IBM POS from configuring the MP72, refer to the MP72 Scanner Scale Barcode Programming Guide for information on RS-485 and IBM USB configuration, beep, scale, and type directives.
