RTU-to-RTU Connection

RTU-to-RTU Asynchronous Communications Connection

This section provides data on the cable (not supplied) recommended for the RTU-to-RTU
RS232 asynchronous interconnection (refer to Figure 22). The following table defines the
RTU port for this connection type.
Port No. Configurator Definition
1B RS-232 UART RTU-to-RTU (MDLC)
2 RS-232 UART RTU-to-RTU (MDLC)
When the connector is facing upwards, the left-hand pin is Pin No. 1,
and the right-hand pin is Pin No. 8.
