CLASS 3400 METER
62-0391-01 24
6.9.2 External Modem
1. All meters should be connected to the RS-232 key as described in 6.8.2.
2. DISCONNECT POWER TO THE RS-232 KEY. Remove the cover by removing
the 2 screws from the bottom of the enclosure.
3. On the circuit board, locate the blue jumpers J7 (MODEM) and J8 (ex-MODEM).
If these jumpers are set in the DIRECT position, you must move the jumpers so
they are set in the MODEM position. Replace the cover and secure the enclo-
sure.
4. Connect the RS-232 key to the external modem using the supplied 8-conductor
flat modular cable.
5. Connect the 9VDC adapter to the power input on the back of the RS-232 key
and plug it into a 120VAC outlet.
IMPORTANT:
The modem should use a phone line that is dedicated exclusively to the AMR
system. Do not use a phone line that is shared by another modem or fax
machine.
6.9.3 Baud Rate Selection
The communication baud rate is selected by means of DIP switch S2 positions 3 and 4
on the circuit board. There are four (4) selections: 9600 (factory default), 19200,
38400, and 76800.
1. Select 9600 when using the Class 3400 meter with a modem.
2. The baud rate on the meter must always match the baud rate selected in the E-
Mon Energy software; otherwise, communications will not work.
3. After a baud rate change, press CPU Reset to register the change.
4. All meters in the daisy-chain circuit must be set at the same baud rate.
5. The DIP switch is located above the RS-485 terminals.
NOTE: USE ONLY POSITIONS 3 AND 4 - DO NOT CHANGE ANY OTHER
POINTS.
