Internal Modem Connections

This option is only available on the 9330 and 9350 meters.

Refer to the “Hardware Reference” chapter for internal modem specifications.

Connection to the internal modem is made via the RJ-11 jack, or two captured wire connectors, located on the right side of the meter. Connect the meter to the telephone network with an FCC Part 68 compliant telephone cord (that has two male RJ-11 plugs). If you have the captured wire connector option, connect the meter to the telephone system with the (bare wire to RJ-11) cable provided. If you have the CTR-21 compliant internal modem option, you may also require an adaptor to interface with your regional telephone jack.

The meter with an internal modem uses the modem to communicate to a master device (e.g. server computer with WinPM.Net software) over the telephone network.

Meter Setup for Modem Communications

To enable communications through the meter’s internal modem, you must configure the Comm 1 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.

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 COM 1 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.
