ADC power input connector — Plug the included external 12 VDC power supply into either this 2-pole connector (see Power supply wiring on page 13 to wire the power connector) or the power input connector on the receiver (see the user guide of your respective receiver for more information).

BOver DTP control port — Connect an RS-232 device to this 3-pole, 3.5 mm captive screw connector for pass-through RS-232 control (see RS-232 and IR Connector Wiring on page 14 to properly wire the RS-232 connector).

CRemote (RS-232 and contact closure) control port — Connect an RS-232 device, contact closure device, or both to this 5-pole, 3.5 mm captive screw connector to control switching on the unit (see RS-232 and IR Connector Wiring on page 14 to properly wire the Remote connector).

•RS-232— To control the unit through this port, connect an RS-232 device and configure it as follows: 9600 baud rate, 8 data bits, 1 stop bit, no parity.

•Contact — Momentarily short pins 1 or 2 to ground (G) to select the corresponding input. Connect pins 1 and 2 to ground (G) to set the unit to auto switch mode. The device will select the highest active input.

DDTP Out port — Connect one end of the twisted pair cable to the RJ-45 connector on the transmitter (see TP Cable Termination and Recommendations on page 12 to properly wire the RJ-45 connectors). Connect the opposite end of the cable to the appropriate receiver.

ATTENTION: Do not connect this device to a telecommunications or computer data network.

EReset button — Use an Extron Tweeker or small screwdriver to press and hold the recessed button for 6 seconds while the extender is running to perform a factory reset.
