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.
N If 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.
N The SW DVI A Series switchers are not compatible with
HDCP signals.

Video output connector — Connect a DVI-D display device to
this female DVI-I connector. Each time a display is powered
on and connected to the switcher's output connector, the EDID
information is read from the connected output device and
written to non-volatile memory on each input.
N The EDID information is also read and stored whenever
power is recycled to the output device or the output
device is replaced.
c
Remote and autoswitching connector — This 5-pole,
3.5 mm captive screw connector (labeled "Remote/Auto-Sw")
can be used for RS-232 communication with the SW2/SW4
and/or to enable autoswitching.
• To enable RS-232 control, connect pins Tx (transmit),
Rx (receive) and _ (ground) to your computer's serial port.
(See "Wiring for RS-232," later in this chapter.)
• 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.
