Electro-Voice 1252, 250 operation manual Modbus/Tcp

RJ-45 Network Connection allows a Nexus Meter with the Internal Network Option to communicate with multiple PC’s concurrently. No other hardware is necessary for this easy-to-use connection. The Nexus Meter with the Internal Network Option can connect via RS-485 to other Nexus Meters in local or remote sites in a daisy chain configuration, as depicted below.

The Nexus 1250/1252 Meter with the Internal Network Option has a unique label; Port 2 is labeled Ethernet Gateway. If you are going to use RS-485 to connect multiple Nexus meters via the net- work, you MUST use the Ethernet Gateway. For more details, see Chapter 11 of this manual.
