connecting your VM-2D, connect its power and then switch on the power to each device.
To connect VM-2D as illustrated in the example in Figure 2:
1. Connect a DVI source (for example, a PC) to the INPUT connector .
2. Connect the output connectors to one or both DVI acceptors, as follows:
▪OUT 1 connector to DVI acceptor 1 (for example, a projector).
▪OUT 2 connector to DVI acceptor 2 (for example, a display).
3. Connect the 5V DC power adapter (wall transformer) to the 5V DC socket and
connect the transformer to the mains electricity.
4. Acquire the EDID (see Acquiring EDID on page 6).
Figure 2: Connecting VM-2D
Acquiring EDID

Acquiring EDID via front panel
Press EDID once to display the current EDID source which is indicated by the flashing of
OUT 1, OUT 2, or both (if the default EDID is currently used).
To acquire an EDID:
1. Press EDID .
The current EDID source is displayed.
2. Press EDID (a second time) to enter EDID select mode.
VM-2D enters EDID select mode.
3. Press EDID repeatedly to cycle through the EDID source selection options.
The OUT LEDs flash in the following order:
OUT 1 -> OUT 2 -> all output LEDs flash (default EDID).
4. Stop pressing EDID once the required EDID source is reached.
After a few seconds VM-2D acquires the EDID.
When complete, all output LEDS return to normal operation, displaying the present
output connection status.
If an unconnected output is selected or the connected EDID cannot be read, VM-2D acquires
the default EDID.
Forcing RGB Mode
Normally (the default state), when acquiring the 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 EDID for 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 EDID for 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.
Upon power on, the output LEDs flash according to their EDID mode: four times for RGB
mode and once for normal mode.
