1Connect to IP service port 7701 for Modbus RTU communications over Ethernet. The Modbus Unit ID of the meter over Ethernet is 100.

2See the technical note Time Synchronization and Timekeeping for details about GPS.

3IEC870-102, EtherGate and ModemGate are only available on COM1 and COM2.

4This setting only applies if you have ordered the internal modem option (see below).

5The factory set Unit ID for COM1 is based on the serial number of the meter, using the last four numbers before the dash. For example, if the serial number is PA-0009B263-01, the Unit ID is set in the factory to 9263. After a factory reset, the unit ID number will default to 100.

Services if you require more information.

Internal Modem Setup

If you have the internal modem order option, you disable the IrDA optical port on COM3 by selecting MODEM for the Mode setting. The modem is factory configured to answer in the number of rings specified by Answer HR Rings (the Non-Answer HR Rings value is ignored by default).

A list of compatible AT commands is provided on the website and the technical note Modem AT Commands for ION Meters. Visit the web site for the latest modem configuration files.
