4Contact closure control connector — Connect an optional contact closure device to this female 5-pole captive screw connector. Making contact closure between pins A and B transmits a channel signal through the RS-232 port. Extron’s RGB 580xi I AAP and RGB 580xi SI/CCSI AAP (see “AAP Device Features” and “Cable Cubby AAP Device Features” in this chapter) provide a one-button contact closure operation. Wire the male connector as shown below on the left. Extron’s VGA and control cable assembly (see chapter A, “Cables”, for part numbers) comes with the male control connector prewired as shown below on the right.

1Power/signal LED — This LED lights amber to indicate that the RGB 580xi interface is receiving power, and lights green to indicate it is receiving both power and an input signal.

2Audio input connector — Plug a 3.5 mm stereo plug into this jack for unbalanced audio input. Wire the male plug as shown below.

5Video output: level control — This control adjusts picture brightness by compensating for signal amplitude loss caused by cable resistance. See Front Panel Adjustments in this chapter.

6Video output: peaking control — This control adjusts picture sharpness by compensating for cable capacitance caused by long cable runs. See Front Panel Adjustments in this chapter.

7DIP switches — This bank of DIP switches, as illustrated below, controls DDSP (Digital Display Sync Processing), serration pulse output, SOG (sync on green) output, vertical sync width, sync polarity, and composite sync output. Moving a switch up sets it to On and moving it down sets it to Off.
