8: Micro125 Implementation The Modbus master/slave functionality on the Micro125 is similar to the Modbus implementation on other platforms such as the xPico-IAP and xDirect-IAP. The Micro125 product does not support configurable pins, so they are not applicable in the Setup Menu. The Micro125 has 1 serial port. In this serial port, hence the firmware uses for sending and receiving Modbus/RTU or Modbus/ASCII serial data under the Serial & Mode Settings menu option. The setting for each configuration option is displayed in the setup menu.
