Wiring for Modems
External Modems
The type of phone line required for communication via an external modem depends upon the
type of modem used and the method of communication desired. Refer to the manual that is
provided with the modem, for specific requirements.
Internal Modem
When the TopKAT internal modem is installed, Port 3 communication is routed through the
modem in place of being wired at the DC Junction box. Jumper K2 should be removed. Refer
to
on
for location of jumpers K1 and K2. The phone line for the
internal modem can be installed in the DC conduit. If you are installing it in the DC conduit,
the cable must be two twisted-pair shielded cable as specified in
on
and the shield drain wire must be connected to the system AC
ground. Check with your local phone company for proper installation of the phone line.
