— Use this five-pole connector for an
RS-232 connection to a PC for entering SIS commands and using
the Windows-based control software, and/or for connecting the
wired IR Link. See “Wiring and Connecting the RS-232 Cable,”
on the next page, for information on connecting to this port.

Wiring and Connecting the RS-232 Cable
To connect your computer or control system to the RS-232
connector, use a male 9-pin, D-to-bare-wire RS-232 cable or a
universal control cable (UC 50', UC 100', or UC 200'). One end
of the UC cable is terminated with a female 9-pin, D connector,
and the other end is unterminated. Wire the unterminated end
to the provided five-pin captive screw plug.
The following diagram shows the UC cable’s pin assignments.

Wire the RS-232 cable to the five-pole captive screw
connector, provided with the AVT 100, as described below
(see the illustration on page 2-7). Connect only the red,
orange, and green wires in the cable; and use only the first
three pins on the connector, starting at the left.

Wiring the AVT 100 to a PC or control station
through the RS-232/IR port
Connecting the AVT 100 to the IR Link
The optional IR Link Infrared Signal Repeater can be connected
directly to an AVT 100. To wire the IR Link for use with your
AVT 100,
1
.
Prepare the site and install a wall box, following the
directions in the
IR Link User’s Manual
, provided with your
IR Link equipment.
2
.
Cut a length of 150' (45 m) or less of Extron Comm-Link
(CTL or CTLP) cable to go between the AVT 100 and the IR
Link.
3
.
Attach a 3.5 mm, 5-pole captive screw connector to each
end of the cable. Only three wires (between pins A, B, and
D on the IR Link end, and pins Ground, IR, and +12 V on
the AVT 100 end) are required. Wire the cable as shown in
the illustration on the next page. Connectors are included
with the IR Link, but the cable must be purchased
separately.
4
.
Plug the 5-pole connector into one of the IR Link’s
communications connectors.
