2.2 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
•Position your VS-21H-IR 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.

5 Connecting the VS-21H-IR 2x1 HDMI Switcher
To connect the VS-21H-IR, as the example in Figure 2 shows, do the
following1
1. Connect up to two HDMI sources to the INPUT connectors, using the
Kramer HDMI cables: INPUT 1 connector to HDMI source 1 (for
example, DVD Player 1) and INPUT 2 connector to HDMI source 2
(for example, DVD Player 2).
:
2. Connect the OUTPUT connector to the HDMI acceptor (for example,
a plasma display), using the Kramer HDMI cable.
3. Connect the 12V DC power adapter to the power socket and connect
the adapter to the mains electricity.
4. Press the SELECT button2
to choose which HDMI input to route to
the output. The SELECT button toggles between INPUT 1 and INPUT
2, lighting the IN 1 LED when INPUT 1 is selected, or the IN 2 LED
when IN 2 is selected.

to switch INPUT 1 or 2 to the
output. Before doing so, set it to work with the VS-21H-IR by assigning a
GROUP number.
1. Point the remote control transmitter at the remote receiver (item 10 in
Figure 1 / Table 1) and press the GROUP key.
2. Press key 11.
This sets and saves the group number.
To switch INPUT 1 or 2 to the output via the remote control transmitter,
press key 1 or 2.
6 Operating the VS-21H-IR 2x1 HDMI Switcher
This section describes how to operate the VS-21H-IR, using the SELECT
button. The VS-21H-IR functions in two modes: the PC mode2(see Section
6.1) and the DVD mode (see Section 6.2
6.1 Working in the PC Mode
).
This section describes how to acquire / change the EDID (see Section 6.1.1)
and how to reset the default EDID (see 6.1.2Section
Note that if a PC is connected to the input, and the EDID is acquired while
running video on-screen, the video will stop running and then will either restart
automatically or will need to be restarted via the graphics card display
definitions, depending on the type of graphics card installed in the PC.
) when working in the
PC mode.
6.1.1 Acquiring / Changing the EDID
You can work with the default EDID or acquire / change the EDID.
To acquire or change the EDID:
1. Connect the new output display device.
If no output display device is connected to the output, the default
EDID is stored in the non-volatile memory.
1 The setup parameters for the remote control transmitter are as follows: router number = 1 (default); group number = 11,
single digit mode (default), video (default). For further details, see the RC-IR2 user manual
2 The default

2. Connect the power while keeping the SELECT button pressed until
the LEDs start to flash.
3. Release the SELECT button while the IN 1, IN 2 and OUT LEDs
flash.
The EDID of both INPUT 1 and 2 is altered and stored in the
non-volatile memory.
When a certain input—INPUT 1 or INPUT 2—is selected, the EDID
information comes directly from the display. When the input is not selected,
the VS-21H-IR uses the virtual EDID stored in the non-volatile memory.
6.1.2 Resetting to the Default EDID
To reset the default EDID, do the following:
1. Disconnect the power.
2. Disconnect the output cable.
3. Connect the power while keeping the SELECT button pressed until
the IN 1, IN 2 and OUT LEDs flash.
6.2 Working in the DVD Mode
In the DVD mode, an unselected input will not receive any EDID data. The
selected input will receive the EDID data directly from the display device.
6.2.1 Toggling from the DVD mode to the PC mode
To toggle from the DVD mode to the PC mode:
1. Press and hold the SELECT button for a few seconds until both
INPUT LEDs flash, while the device is powered on.
2. Release the SELECT button.
The VS-21H-IR switches to the PC mode.
6.2.2 Toggling from the PC mode to the DVD mode
To toggle from the PC mode to the DVD mode:
1. Press and hold the SELECT button until both INPUT LEDs light
continuously without flashing, while the device is powered on.
2. Release the SELECT button.
The VS-21HDMI-IR switches to DVD mode.
