power is recycled to the output device or the output

device is replaced.

C Remote and autoswitching connector — This 5-pole,

3.5mm captive screw connector (labeled “Remote/Auto-Sw”) can be used for RS-232 communication with the SW2/SW4 and/or to enable autoswitching.

A	Video input connectors — Connect DVI-D video input devices
	to these female DVI-I connectors. EDID information from the

output display is written to non-volatile memory on each input, allowing the source to perform as if connected to the display, even when it is switched away from it.

NIf power is recycled to the display, or if a new display is connected, the input sources do not read the EDID information until they are rebooted.

By factory default, the EDID stored on all inputs contains information for a resolution of 1024x768 @ 60 Hz.

	• To enable autoswitching, short pins 4 and 5 of this
	connector together. In autoswitch mode, the switcher
	automatically switches to the highest numbered active
	input. (See “Enabling autoswitching,” later in this chapter.)
D	Audio output connector — Connect the audio cable from your
	display device to this 5-pole, 3.5 mm captive screw connector for
	balanced or unbalanced audio. (See "Audio Connectors," later
	in this chapter.)
	N If the output device is wired for unbalanced audio, the
	gain is unity. If the output is wired for balanced audio, a
	+6 dB gain is applied.
E	Audio input connectors — Connect the audio cable(s) from
	your input source(s) to these 3.5 mm TRS mini jacks for
	unbalanced stereo audio.
F	Power connector — Plug the external 12 VDC power supply
	into this 2-pole, 3.5 mm captive screw connector.
