Internal Modem Connections

Refer to the “Hardware Reference” chapter for internal modem specifications for the ION 7500 and ION 7600 meters.

This section only applies if your meter has an internal modem option. Depending on the ION meter and its date of manufacture, the installed optional internal modem could be one of two different brands. The Conexant modem is the older type modem, and is available in North American (FCC approved) or European (CTR-21 compliant) versions. The newer modem is manufactured by Multi-Tech and is a universal modem that can be readily used in most countries, and complies with FCC, Industry Canada and TBR-21 regulations — refer to the Notices at the start of this document for more details.

The internal modem shares the communications channel with the optical port. It is factory-configured to respond (and the optical port is disabled). To enable communications through the meter’s internal modem, you must configure the Comm 3 Communications module. The Baud Rate, Unit ID, and Protocol setup registers must properly match your system, and the initialization string for the internal modem must be set up using the ModemInit register.

NOTE

The internal modem is multiplexed with the IrDA optical port on the meter’s front panel, so only one channel can be in use at a time. To use the modem, the Comm Mode setup register of the Comm 3 Communications module must be set to Modem (the default value).

ModemInit Setup Register

The ModemInit string register defines the initialization string for the internal modem, with a maximum of 47 characters. Edit the ModemInit register and enter the initialization string desired. The string is sent to the modem as soon as you download the COM1 module. Note that the string is also sent to the modem whenever the meter is powered up, or whenever the baud rate in the Comm 1 Communications module is changed. Any changes to the Modem Init or Baud Rate setup registers while the modem is online will cause the modem to disconnect from the phone line.

CAUTION

Changing the ModemInit setup register while the internal modem is online causes the modem to disconnect from the phone line.
