Outputs

2Video output 1 — Connect an output monitor or other VGA device to this female 15-pin HD connector.

3Audio output 1 — Connect speakers to this 3.5 mm stereo jack.

4Video output 2 — Connect a projector or other RGBHV video output device to these five BNC connectors.

5Audio output 2 — Connect speakers to this 5-pole 3.5 mm captive screw connector. Wire the captive screw connector for stereo output as shown in figure 2-6. Use the supplied tie-wrap to strap the audio cable to the extended tail of the connector.

CAUTION	Connect the sleeve to ground (Gnd). Connecting
	the sleeve to a negative (-) terminal will damage the
	audio output circuits.

The length of exposed (stripped) copper wires is critical.

The ideal length is 3/16” (5 mm).

•If the stripped section of wire is longer than 3/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 3/16”, wires can be easily pulled out even if tightly fastened by the captive screws.

Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could be pulled out.

Remote control connections

6Remote connector — Connect a computer or RS-232 control module to this female 9-pin D connector to allow remote control using the Extron Simple Instruction Set™ (SIS™) or the Extron Universal Switcher Control Program. Alternatively, connect a contact closure device such as an Extron remote control Architectural Adapter Plate (AAP or MAAP). See chapter 3, “Remote Control”, for more information.

7Tally Power connector — This 2-pole captive screw connector provides power to light the LEDs on Extron MMX 32 AAP (part #70-277-01, -11, or -21) or MMX 32 MAAP (part #70-277-12, or -22) contact closure remote control panels. Connect the 5V and Gnd (-) 2-pole captive screw connector on the AAP or MAAP to this connector. See chapter 3, “Remote Control”, for more information.

Power connection

8Power connector — An external 12V power supply is included with the unit. Plug it into this 2-pole 3.5 mm captive screw connector. Wire the connector as shown in figure 2-7. Use the supplied tie-wrap to strap the power cable to the extended tail of the connector.

The length of exposed (stripped) copper wires is critical.

The ideal length is 5/16" (7 mm).

•If the stripped section of wire is longer than 5/16”, the exposed wires may touch, causing a short circuit between them.

•If the stripped section of wire is shorter than 5/16”, wires can be easily pulled out even if tightly fastened

by the captive screws.
