Connecting the Modem
Connect the 9700 Power Meter-MDM modem via the RJ-11 jack located on
the top of the meter. An FCC compliant telephone cord is provided that has
two male RJ-11 plugs. Connect the meter to your telephone network using
the cable provided (if you use a different cable, ensure that it is FCC Part 68
compliant). Follow these steps to connect the modem to your telephone
network:
1. Install the meter into its mounting location and connect the power
supply, communications connections, and voltage and current inputs as
described in the

Installation and Basic Setup Instructions

shipped with
the meter.
2. Plug the telephone cord into the modem’s RJ-11 socket, located on the
top of the meter (labeled MODEM).
3. Plug the other end of the telephone cable into the telephone jack that
connects to the telephone network.
4. Power up the meter.
5. Using WinPM, configure the Comm 1 Communication’s module settings
(described below).

Communications Module Settings

The Comm 1 Communications module on the 9700 Power Meter has one
additional setup register labeled

ModemInit

. This string register defines the
initialization string for the internal modem, using a maximum of 47
characters.
Edit the

ModemIni

t register and enter the initialization string desired. The
string is sent to the modem as soon as you download (Send & Save) the
Comm 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.

Verifying Communications

There are four LEDs on the top of the 9700 Power Meter to help you verify
that the modem is communicating properly. Beside the RJ-11 (or captured
wire) connector marked MODEM, are two LEDs marked TXD and CD.
