can be intimidating to users new to serial communications. Therefore, we recommend reading
each of the following topics carefully before designing your serial network:
• Configuring the RMC SERIAL
• Line Drivers: RS-232/422/485
• Serial Network Topologies
• RS-232 Wiring for the RMC SERIAL
• RS-422/485 Wiring for the RMC SERIAL
• RS-422/485 Termination and Biasing
Finally, the following topics describe how to use each protocol supported by the RMC SERIAL:
• Using Modbus/RTU with the RMC SERIAL
• Using DF1 (Full- and Half-Duplex) with the RMC SERIAL
• Using the Mitsubishi Bidirectional Protocol with the RMC SERIAL
• Using the Mitsubishi No Protocol with the RMC SERIAL
5.5.2 Configuration and Wiring
5.5.2.1 Configuring the RMC SERIAL
The RMC SERIAL module adds a single serial port to the RMC for communications with other
devices such as HMIs and PLCs. However that one serial port has a great amount of flexibility. It
supports most standard serial port options (e.g. baud rate and parity), several protocols, and
several line drivers with their associated options (e.g. flow control, termination, and biasing).
These settings are changed through RMCWin and saved in the RMC CPU's Flash memory. To
change these settings:
1. On the Tools menu, click Module Configuration.
2. In the Slots list, click the Serial line.
3. Click Slot Options.
4. In the Serial Module Options dialog box, make all changes.
5. Click Update RMC.
This step will save the settings to Flash memory.
The Update Module Configuration dialog box will be displayed to indicate the progress. If the
RMC could not be reset automatically, you may be prompted to remove power and reset the
RMC manually.
6. In the RMC Configuration dialog box, click Close.
