IR pin out will be
determined by the IR cable
and will connect as

(signal)
Connecting
The captive screw connectors have
a contact bar that is adjusted to
compress the wire against the top
contact plate. Use the screws at the
top of the connector to compress
the wire against the contact plate.
When connecting the cables to the female captive screw connector it is important that the wires be
terminated correctly. The female captive screw connector has a contact plate at the top and must
have the wires touching it for signal to pass. When wired correctly
(see picture A)
the signal will pass,
incorrectly
(see picture B)
no signal will pass.

Captive Screw
The captive screw connectors allow you to cut cables to a suitable length, reducing cable clutter
while providing a more reliable connection.
RS-232 captive screw connector is included. RS-232 pin out will be determined by the RS-232 cable
and will connect as Rx
(receiver)
,
Tx
(transmitter)
,
and
(ground)
.
(See picture 1)

IR
One side of the optional IR cable is marked
to differenciate pin outs.
There are two wires on the optional IR captive screw ready cable
(AT-LC-CS-IR-2M sold separately)
: signal
and ground. The signal wire is red and ground wire is black. The IR cable will plug into the IR IN
ports and connect to third party control systems.
