Wiring for Modems
External Modems
The type of phone line required for communication via an external modem is contingent upon
the type of modem used and the method of communication desired. Consult the manual that
comes with the modem for specific requirements.
Internal Modems
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. See
“Terminal Block ID” on page 26
for location of jumpers K1 & K2. The phone line for the
internal modem can be installed in the DC conduit. If installing in DC conduit, cable must be
two twisted-pair shielded cable as specified in
“Communication Requirements” on page 21
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.
