6.9.1 Modem (RS-232 KEY RM)
The RS-232 key with modem connects the entire RS-485 network of E-Mon Class
3200 meters to a telephone line.
** Refer to Section 6.7 for RS-485 network connections.
On the back panel of the RS-232 key/modem, the left jack (RS232) is not used in
most cases since there is no local host computer.
The two jacks at the top center of the rear panel on the RS-232 key/modem are
for connecting the phone line. Connect either one of these two jacks to the
telephone line.
IMPORTANT:
The telephone line should be dedicated exclusively to the automatic meter
reading system. Never connect to a telephone line used by other modems
or fax machines. If there are telephones connected to this phone line, the
proprietor must be aware that all phones must be on "hook" in order for
the modem to work. A dedicated phone line is suggested for system reli-
ability.
