NSimultaneously connecting both pins 1 and 2 to ground (pin 3) turns autoswitching mode on.

Autoswitching —

NAutoswitch mode must be disabled when daisy chaining VSW 2VGA A switchers. If the autoswitch mode is enabled, the switchers cannot be daisy chained.

NRGsB and RsGsBs inputs and outputs occur in manual mode only.

NAutoswitching 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 CONTACT

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.

NWhen 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

NIf 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.

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