Mode A Configuration
When in Mode A, each press of the rotary wheel will switch between the different physical ports
available on the unit (VGA and audio). When selected to a video output, rotating the wheel will
toggle the output ON or OFF. When selected to an audio output, rotating the wheel will increase
or decrease the volume output accordingly. The LED strength will reflect the volume level (i.e.
brighter indicates higher volume).
Mode B Configuration
When in Mode B, each press of the rotary wheel switches between the different signal calibration
modes: equalization, gain, red skew, green skew and blue skew. Rotating the wheel in any of
these calibration modes will adjust the output signal accordingly.
NOTE:
Before selecting Mode B, first enter Mode A and select a video output connector. Then
when entering Mode B, the video calibration will affect that output only. If using both outputs
on the Remote unit, this process will need to be done to both separately.
EDID Copy
In some cases display problems may arise due to incorrect EDID communication between the
display device and the computer graphics card or insufficient EDID data programmed into the
display device. The Local Unit provides an “EDID Copy” feature that allows the Local Unit to read
the necessary EDID information from the locally attached display device and then provide it, at
all times, to the attached video source. If no new EDID information is available from a display
device, a default profile built into the Local Unit is automatically provided.
Load Default EDID
When using a non-EDID compliant display device, the ST122UTPAL can automatically select
viable EDID data from the Unit’s default EDID profile to set the EDID information up. Users can
enable this default EDID profile by following the instructions below:
1. Press and Hold the button “EDID Copy” on the side panel of the Local Unit.
2. Plug in the provided power adapter to the Local Unit, while still holding the button.
3. Release the “EDID Copy” button immediately after one confirmation beep. The power LED
light will be steady green, indicating that the EDID copy (communication) is completed and
the default profile loaded.
