IR In connector — Connect the IR sensor cable (provided)
B
to the third, fourth, and fifth pins of this 3.5 mm, 5-pole
captive screw connector (see the illustration at right).
NOTE: The cable length for the IR sensor is 6 feet
(1.8 meters). Do not extend the IR sensor cable
beyond 21 feet (6.4 meters).
Control Out Contact connector (captive screw) —
C
(Optional) Plug a contact closure device into pins 1 through
6 and the first ground (
captive screw connector, and plug the other end of the
cable into the contact closure device.
Control Out RS-232 connector (captive screw) —
D
Plug the RS-232 output cable into the Tx, Rx, and second
_
ground ( ) of this 3.5 mm, 10-pole captive screw connector.
Plug the other end of the cable into the RS-232 control port
of the switcher or the SMD 202. This permits the IR 102 Rx
remote receiver to control the device.
NOTES:
•
The IR 102 Kit can be used with an Extron MPS 112
switcher only when the switcher is in single switch
mode (see the MPS 112 User Guide).
• You are not able to connect a contact closure
device to this port while an RS-232 cable is
connected to it.
RS-232/Contact – Out connector (9-pin D) — Connect
E
an RS-232 or contact closure device output cable between
this 9-pin D connector and the contact closure or RS-232
control port of the switcher or SMD 202. This permits the IR 102 Rx remote receiver
to control the device. The pin assignments are shown in figure 3.

NOTES:
•
Connect an RS-232 cable or a contact closure device to this connector, but
not both. Remove the pins that are not needed.
•
The cable used to connect the RS-232/Contact – Out connector to a
computer, control system, or contact closure device may need to be
modified by removing pins or cutting wires. If unneeded pins are connected,
the system may suspend communication indefinitely.
