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 enclosure.
4. Connect the RS-232 key to the external modem using the supplied 8-con-
ductor 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 on the E-Mon Class 3200 meter is set through
positions 3 and 4 on DIP switch S2 on the meter circuit board. The default is 9600
Baud.
1. Select 9600 when using the E-Mon Class 3200 meter with a modem.
2. The Baud rate on the meter must always match the Baud rate selected in
the Honeywell Energy software; otherwise, communications will not func-
tion.
3. After a Baud change, press the CPU reset button to register the change.
4. All meters in the daisy-chain circuit must be set at the same Baud rate.
