• Pin 2 selects Input 2 when momentarily connected to
ground (pin 3).
• Ground connects to the ground wire (equipment
ground).
N Simultaneously connecting both pins 1 and 2 to
ground (pin 3) turns autoswitching mode on.
Autoswitching —
N Autoswitch mode must be disabled when daisy chaining
VSW 2VGA A switchers. If the autoswitch mode is
enabled, the switchers cannot be daisy chained.
N RGsB and RsGsBs inputs and outputs occur in manual
mode only.
N Autoswitching requires TTL level sync on pin 13 of the
15-pin HD connector.
Pins 1, 2, and Ground when jumpered/shorted together (as
shown at right) turn the autoswitching mode on. When
the autoswitching mode is on, the switcher automatically
switches to the input that has an active sync signal.
If both inputs have an active sync signal present, input
2 is selected, and the input 2 LED indicator lights. If no active
sync signal is present, the input 1 LED indicator still lights to
indicate that the unit is still powered on.
N When the autoswitch mode is active, both daisy chaining
and the front panel's input toggle switch are disabled,
and the input cannot be manually switched. Any attempt
to toggle the switch while the switcher is in this mode
results in the flashing of the currently active input's
LED indicator. Contact closure is also disabled while in
autoswitch mode.
Setting the VSW 2VGA A Jumpers
N If you plan to use the VSW I AAP and/or create a daisy
chain configuration, you must configure the switchers
before installing them in a rack or furniture and making
connections.
Daisy chaining VSW 2VGA A switchers requires you to check
and/or set internal jumpers in the switcher.

. If applicable, disconnect all power to the switcher and any
