COM A - B
These bi-directional 6-pin, 6-position RJ11 modular jacks are used to control
additional audio/visual equipment via their RS-232 ports. Refer to the pinout table on
the previous page.
IR OUT A - D
These 3.5mm mini phone jacks are used to control IR devices. Insert the mono mini
plug of the STIRP and place the STIRP shell over the IR sensor window of the A/V
equipment. Also, the Crestron relay controller (SP-RY) or slide controller (SP-SC)
can be connected to these phone jacks.
RF
This 50 ohm BNC connector attaches to the supplied antenna which is used to
receive RF signals from the user interface. In some installations, the RF reception
range can be increased by mounting the antenna away from the equipment with a
BNC male to BNC female 50 ohm cable (not included).
ST-CP Indicators
There are 10 LED indicators located on the front panel of the ST-CP. Refer to
