Dip Switch Settings
The Model VS-2X2 provides a convenient dip switch for setting the desired mode of operation. It is
recommended to set the jumper prior to applying power to the unit, however the device does monitor the dip
switch settings when on and changes mode of operation as needed.
Normal:
This is the default mode setting for the switch. In this mode the unit is controlled from the push-button
switch cord. The switch at the end of the cable is momentary and it has a built-in LED. The LED is used to
indicate which input is selected. Solid on means Input 1, blinking means Input 2 (when blanking mode is
enabled, LED off means blanked output). Every time you press the button the output switches from the
current input to the other input. When blank mode is on, double clicking the button will blank the output
screen.
Auto:
If selected, causes the switch to select the input with active video automatically. The presence of video is
determined by examining the V.Sync signal of the input connectors.
In Auto mode you don’t need to have the pushbutton cord plugged in. However, if a push button cord is
plugged-in, the button itself cannot be used for switching, but the LED either stays on or blinks to indicate
which input is selected. Additionally, it is possible to blank the output in auto mode using the push-button
switch (see Blank dip switch function below)
