3. Modbus Gateway Setup and Connections

This section describes how to setup and connect MESR9xx Modbus Gateways.

Note: In this section devices to be connected to the Modbus gateway’s serial connection are simply referred to as the “Modbus network”.

Connecting the Power Supply

Connect a DC power supply to the power terminals on the top of the Modbus gateway. Polarity of the wires is indicated on the label on the side of the Modbus gateway. Acceptable voltages are between 10 VDC and 48 VDC. The power supply must be capable of supplying 4 Watts for MESR90x units or 6 Watts fro MESR92x units.
