6.7 Honeywell E-Mon Energy RS-485 Wiring
(continued)
After performing these steps, all of the meters will be connected in a daisy chain
configuration. This network of meters can then be connected to the RS-485
network and communication can be established.
Internal Modem (if ordered as option)
An optional internal modem inside one meter will communicate with the others
via the RS-485 network. Simply connect one of the two telephone jacks on the
modem to the telephone line to complete the installation.
Local Computer
A local computer installed in the building can communicate with the RS-485
network. The computer must be connected to an RS-232 key. The RS-232 key is
then connected to an available RS-485 jack in the meter using an RJ-11 cable.
NOTE:
Don’t confuse the modem’s telephone jacks with the RS-485 jacks!!!
NOTE:
When using one meter with an internal modem, only the telephone line is
connected. RS-485 is not needed.
6.8 RS-232 Communications
6.8.1 Hard wired System using the RS-232
Communication Key
The RS-232 communications key allows you to connect Class 3400 meters to a
personal computer that has the Honeywell E-Mon Energy™ software installed.
The computer communicates with the meters through the RS-232 key.
The RS-232 key must be located within 15 feet of the host computer.
