Figure 30: Wiring The Levelmaster To The Rmc-100 (Onboard Comm Port); Figure 31: Wiring The Levelmaster To Ethernet-To-Serial Converter And The Rmc-100 - ABB LevelMaster 7100 User Manual

Figure 31 shows how to wire the LevelMaster to a third-party Ethernet-to-serial converter which is connected to the RMC-100. In
this configuration, the RS-485 communication with the remote controller is handled through the serial port on the converter. The
onboard COMM ports are used only for powering the LevelMaster. For more details on the connection to the RMC-100, refer to
the RMC user manual.
