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
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-2HN away from moisture, excessive sunlight and
dust

VM-2HN - Connecting the VM-2HN
Always switch off the power to each device before connecting it to your
VM-2HN. After connecting your VM-2HN, connect its power and then
switch on the power to each device.
i
4 Connecting the VM-2HN
Connect the VM-2HN as illustrated in the example in Figure 2:
1. Connect an HDMI input source (for example, a Blu-ray player) to the HDMI
IN connector.
2. Connect the two OUTPUT connectors to up to two HDMI acceptors, as
follows:
Not all outputs need to be connected.
HDMI OUT 1 connector to HDMI acceptor 1 (for example, display 1)
HDMI OUT 2 connector to HDMI acceptor 2 (for example, display 2)
3. Connect the 5V DC power adapter to the power socket unit and then
connect the adapter to the mains electricity (not shown in Figure 2).

4.1 Acquiring an EDID
To acquire an EDID, press the EDID SETUP button as follows:
1. The first press of the EDID SETUP button displays the present EDID status
similar to that shown in the next step.
2. The second press of EDID SETUP enters the read mode and each
additional press cycles through the source options:
OUT 1 -> OUT 2 -> all LEDS flash slowly for auto-mix -> all LEDs flash
quickly for a default EDID.
3. When the desired EDID source is reached, release the EDID SETUP button.
The VM-2HN reads the EDID for a few seconds. When finished, all LEDS
return to display the present output connection status.
If an unconnected output is chosen or the EDID cannot be read, the VM-2HN loads the
default EDID.

4.2 Force RGB Mode
The VM-2HN toggles between “Normal” and “Force RGB” modes.
To toggle:
Press the EDID button for three seconds
All input and outputs LEDs flash depending on the selected mode:
In “Normal mode” (not forcing RGB), the LEDs flash once
In “Force RGB mode”, the LEDS flash four times
Note: After setting the Force RGB mode you must re-read the EDID from the
display to update the Force RGB change.
Powering on the device identifies the mode as follows:
In “Normal mode” (not forcing RGB), the LEDs flash once
In “Force RGB mode”, the LEDS flash four times.
The default mode is "Normal".
