hand pin of the communicator PC-LINK header (see Figure 3)).
e. Using light pressure (finger tight only), attach the supplied white quad band whip antenna to
the threaded antenna connection point at top of the panel.
WARNING! - Modules are power limited. Do not route any wiring over the circuit board.
Maintain at least 1in. (25.4mm) separation between circuit board and wiring. A minimum
of ¼ in. (7mm) separation must be maintained at all points between non-power limited
wiring and power limited wiring.
3. To electrically connect the communicator to the panel, perform the following steps (see Figure 3).
a. Disconnect both AC power and battery connections from the panel, and disconnect tele-
phone line.

4. Install the RS-422 connections (R models only). When installing the communicator for use
with 3rd party applications an RS-422 cable must be connected between the 3rd party device
and the communicator module. Maximum cable length for RS-422 cable is 1,000 ft. (305 m).
NOTE: Please refer to the installation manual for the 3rd party device for wiring instructions.
Wire the RS-422 connections as per the table below:
NOTE: The GND connection is optional. DSC recommends connecting GND wire at both ends.

1. Route the CAT 5 Ethernet cable through back of the panel and plug it into the communicator's
RJ45 jack.
2. Perform the following steps for initial power on of the panel with communicator installed:
a. Reconnect the AC power, telephone line, and battery + connector to the panel.
(The communicator and panel will power up together).
