5.6: INP202 Ethernet/Modem Combination

The INP202 Option is an extension of INP200. It has all the features of INP200 plus a built-in

modem. The communication protocol supported by the modem is Modbus ASCII. The

communication protocol supported by the RS485 Ethernet/Modem Gateway is Modbus RTU.

INP202 converts all incoming Modem Modbus ASCII requests to Modbus RTU for internal and

gateway communication. It then converts all response Modbus RTU messages into Modbus ASCII

and sends the responses to the modem.

The Nexus® 1262/1272 meter with the INP202 Option has all the components of an INP200

Nexus® meter plus a built-in modem. It has the capability of connecting to a network through an

Ethernet LAN and with other devices via modem.
