Installation and Wiring

Wiring

The TV sensor, IR emitter, AXlink, and 12 VDC power supply connectors are located on the rear panel of the television controller as shown in FIG. 1 on page 1.

Do not connect power directly to the television controller. If you are using power from AXlink, disconnect the wiring from the Central Controller before connecting the wiring to the television controller. If you are using an optional 12 VDC power supply, apply power to the television controller only when installation is complete.

Wiring guidelines

The television controller requires 12 VDC power to operate properly. The power can be supplied via AXlink cable, or with an optional 12 VDC power supply. The maximum wiring distance between the Central Controller and television controller is determined by power consumption, supplied voltage, and the wire gauge used for the cable.

The following table lists wire sizes and the maximum lengths allowable between the television controller and Central Controller. The maximum wiring lengths are based on a minimum of

13.5volts available at the Central Controller's power supply. If a television controller is installed farther away from the Central Controller than recommended in the table, connect a 12 VDC power supply to the 2-pin 12 VDC PWR connector on the rear panel.

Preparing/connecting captive wires

1.Strip 0.25 inch of wire insulation off all wires.

2.Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section.

Do not tighten the screws excessively; doing so may strip the threads and damage the connector.

TV Sensor connections

Connect the CC-IR to the TV Sensor connector, on the rear panel of the television controller, as shown in FIG. 2 to detect horizontal scan frequencies up to 65 kHz.
