Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM-22H away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

Acquiring the EDID
This is usually done only once, when the machine is being set up in an installation.
Once acquired, the EDID is saved in non-volatile memory and further acquisition is
not necessary.
Initially, the VM-22H operates with the factory default EDID. This lets you connect
the power before connecting one of the acceptors or sources.
You can acquire the EDID from:
One output (the relevant output illuminates)
The default EDID (both output LEDs blink)
Two connected outputs, the auto-mix mode (both output LEDs illuminate)
The EDID acquired is a weighted average of all the connected outputs. For example, if
several displays with different resolutions are connected to the outputs, the acquired
EDID supports all the resolutions, as well as other parameters included in the EDID.
When pressing the EDID SETUP button briefly, the OUT LEDs indicate which type
of EDID was last acquired. If the:
OUT 1 LED illuminates, the OUT 1 EDID is stored in the non-volatile
memory
OUT 2 LED illuminates, the OUT 2 EDID is stored in the non-volatile
memory
OUT 1 and OUT 2 LEDs blink, the Default EDID is stored in the non-volatile
memory
OUT 1 and OUT 2 LEDs illuminate, the Auto-Mix EDID is stored in the non-
volatile memory
To acquire the EDID, do the following:
1. Connect the power.
2. Connect the output or outputs from which you want to acquire the EDID.

3. Press and hold the EDID SETUP button to select the desired EDID.
The OUT LEDs illuminate in the following cycle: OUT 1, OUT 2, both flash
(default) and both illuminate (auto-mix).
4. Release the button when reaching the desired set up.
The EDID is now acquired.
If you set the machine to acquire the EDID from an output that is not connected, the
default EDID is acquired.
