Setting The Vsw 2Vga A Jumpers - Extron electronics VSW 2VGA A User Manual

VSW 2VGA A • User Guide (Continued)
Autoswitching —
•
NOTES:
• Autoswitch mode must be disabled when daisy chaining VSW 2VGA A switchers. If the autoswitch mode is
enabled, the switchers cannot be daisy chained.
• RGsB and RsGsBs inputs and outputs occur in manual mode only.
• Autoswitching requires TTL level sync on pin 13 of the 15-pin HD connector.
Pins 1, 2, and Ground when jumpered and 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.
NOTE:
When autoswitch mode is active, both daisy chaining and the front panel 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 LED indicator. Contact closure is also disabled while in
autoswitch mode.
Setting the VSW 2VGA A Jumpers
NOTE:
If you plan to use the VSW I AAP and 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, set or both internal jumpers in the switcher.
If applicable, disconnect all power to the switcher and any attached devices.

Remove the two screws on each side of the switcher (see figure 6). Remove the four connector nuts on the front panel of the

There are five jumpers, numbered JMP1, and JMP3 through JMP6, that control daisy chaining on the VSW 2VGA A switcher (see
figure 7). Both data and power must be daisy chained from one switcher to another.
