  1. Connect the serial cable between the serial port of the Teleport and the serial port of the Interface Module XC Modbus.

  2. Configure the Buad rate on the meter using the EMH COMBI-TOOL-Software.

    • Navigate to the following menu: Meter —> Interfaces —> Electrical supplement / aditional interface
    • Select a fixed baud rate
  3. Teleport is configured to use the following default Modbus interface configuration of the module (let us know if you use a custom configuration):

    • Device address: 1
    • Baud rate: 9600
    • Stop bits: 1
    • Parity: none
  4. Configure the modbus map, shown in the table below, if that is not already done. All registers should be Holding registers with data type signed integer 32 and register length 2.
