Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
Getting Started
We recommend that you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.

Acquiring and Setting Current EDID
Press the EDID SETUP button once to display the current EDID source: OUT 1, OUT 2,
OUT 3, OUT 4, or all OUT LEDs flash indicating the VM-400HDCPxl default EDID.
To acquire an EDID:
1. Press the EDID SETUP button .
The current EDID status is displayed.
2. Press the EDID SETUP button (a second time).
The device enters EDID setup mode.
3. Press the EDID SETUP button repeatedly.
The device cycles through the EDID source options and the OUT LEDs light up in
the following order: OUT 1 -> OUT 2 -> OUT 3 -> OUT 4 -> all OUT LEDs flash.
Stop pressing the EDID SETUP button once the required EDID source is reached.
4. Wait a few seconds, until VM-400HDCPxl acquires the EDID.
When complete, all OUT LEDs return to normal operation, displaying the present
output connection status.
If an unconnected output is chosen or the connected EDID cannot be read, VM-400HDCPxl
loads the default EDID.
Acquiring a Custom EDID
You can acquire a custom EDID, using the Kramer EDID designer, via the mini USB port on
the front panel.
To acquire a custom EDID:
1. Download EDID Designer to your PC from our website at Kramer EDID Designer.
2. Connect the device to your PC via the mini USB port.

Forcing RGB Mode
Normally (the default state), when acquiring EDID, the device supports any color space that is
defined in the acquired EDID parameters. In case of a color space problem, using the Force
RGB mode may improve the colors of the image on the display.
To
Do the following:
Force the acquired
EDID to support only
RGB color space:
Press and hold the EDID SETUP button for a few seconds until all the output
LEDs flash together four times.
Continue to acquire the desired EDID.
This acquired EDID is then forced to support the RGB color space only.
Return to the normal
EDID mode:
Press and hold the EDID SETUP button for a few seconds until the output LEDs
flash together once.
Continue to acquire the desired EDID.
View the force RGB
activation status:
Power cycle the unit.
All output LEDs flash together once when in normal EDID mode, and four times
when in Force RGB mode.

•Command parameters –Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).
•Command chain separator character –Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).
•Parameters attributes –Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).
The command framing varies according to how you interface with the VS-88UT. The following
