VM-22H - Getting Started
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 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.

VM-22H - Connecting the VM-22H
4 Connecting the VM-22H
Always switch off the power to each device before connecting it to your
VM-22H. After connecting your VM-22H, connect its power and then
switch on the power to each device.
To connect the VM-22H as illustrated in the example in Figure 2:
1. Connect the HDMI source (for example, a DVD player) to the HDMI
IN 1 connector.
2. Connect the HDMI source (for example, a DVD player) to the HDMI
IN 2 connector.
3. Connect the HDMI OUT connectors to up to two HDMI acceptors, as follows:
HDMI OUT 1 connector to an LCD TV
HDMI OUT 2 connector to a plasma display
4. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.
5. Press the EDID SETUP button to acquire or change the EDID information
(see Section 5).

VM-22H - Acquiring the EDID
7
5 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.

VM-22H - Acquiring 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.
