The cable that connects the modem to the telephone network must be
disconnected before opening the meter for servicing.
Baud Rates
The internal modem is capable of using all standard modem protocols from
300 bps to 33600 bps. The baud rate used between connected modems is
independent of the baud rate used for communication between the modem
and the 9700 Power Meter.
ModemGate Functionality
The 9700 Power Meter-MDM’s internal modem is multiplexed with the
Comm 1 communications port. This provides a connection between your
meter, your connected RS-485 loop, and your telephone network. This
connection, referred to as ModemGate, transfers all data received by the
internal modem to the RS-485 loop connected to Comm 1.
