Instruction Manual

When “P1” is selected, “VGA Input Port 1” will automatically be active when the device
connected is turned on, and automatically activate “VGA Input Port 2” when the device
is turned off.
When “P2” is selected “VGA Input Port 2” will automatically be active when the device
connected is turned on, and automatically activate “VGA Input Port 1 when the device
is turned off.
If the active VGA source is turned off, disconnected, or otherwise lost, the switch will
automatically select the next available VGA signal as the priority output. As a result it is
a good idea to prioritize the devices connected based on frequency of use. The device
used the most should be connected to the non-prioritized port.
For Example:
If you typically watch TV through your Cable or Satellite set top box, but sometimes
watch movies on your Blu-ray player. You can connect your set top box to “VGA Input
Port2” and select “P1” on the “Manual / Priority Switch”. Then connect your Blu-ray
player to “VGA Input Port 1”. When the Blu-ray player is turned on to watch a movie
the ST122VGA will automatically switch to the Blu-ray player. When the movie is over,
simply turn off your Blu-ray player and the ST122VGA will automatically switch back to
your set top box.
2. Manual Port Selection
By setting the “Manual / Priority Switch” to “Manual”, allowing you to manually switch
between video sources devices by using the “Manual Select Switch”.
a. Press the “Manual Select Switch” Button to switch between VGA input
devices 1 and 2.
b. The P1 & P2 LED Indicators will light as video sources are selected.
3. EDID Copy
EDID allows the video source to output the most ideal signal to the video display. The
“EDID Copy” function on the ST122VGA ensures that EDID is still active through the
switch. This function allows the system choose the best EDID signal from either of the
connected displays.
a. Set the “EDID Rotary Switch” on the side of the unit to 1.
b. Disconnect the monitor that does not have the EDID/DDC signal you desire, leaving
connected the monitor in which you’ve chosen to copy the EDID/DDC signal from.
c. Ensure the Power Adapter is connected to the AC Wall outlet to the Power
Adapter port.
