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 VS-211HA 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.

VS-211HA - Overview
3 Overview
The VS-211HA is a high-performance automatic standby switcher for HDMI video
and unbalanced stereo audio signals. The VS-211HA can be used as a manual
2x1 switcher or as an automatic switcher. The switcher either uses a priority input
or last connected input.
In priority switching, the signal automatically switches to the secondary input if the
primary signal is lost. If the primary signal reappears, the unit automatically
switches back to the primary input.
In last connected switching, the switcher automatically switches to the newly
introduced input.
In addition, the VS-211HA features:
A maximum data rate of up to 6.75Gbps (2.25Gbps per graphic channel)
HDTV compatibility
HDCP and HDMI compliance
3D pass through
EDID PassThru that passes EDID signals from display to source
DIP-switches for setting the switching mode (manual, auto priority, auto last
connected)
Contact closure remote control for manual operation
Signal auto detect
Parallel unbalanced stereo audio switching
Audio Return Channel (ARC)
No signal on both HDMI inputs triggers the output auto off, to allow displays
to enter sleep mode
Compact DigiTOOLS® size, three units can be rack mounted side-by-side in
a 1U rack space with the optional RK-3T rack adapter

4 Connecting the VS-211HA
Always switch off the power to each device before connecting it to your
VS-211HA. After connecting your VS-211HA, connect its power and
then switch on the power to each device.
To connect the VS-211HA, as illustrated in the example in Figure 2, do the
following:
1. Connect the HDMI input source 1 (for example, Blu-ray player 1) to the IN 1
HDMI connector.
2. Connect the HDMI input source 2 (for example, Blu-ray player 2) to the IN 2
HDMI connector.
3. Connect an unbalanced stereo audio source (for example, stereo player 1)
to the 3.5mm mini jack connector AUDIO IN 1.
4. Connect an unbalanced stereo audio source (for example, stereo player 2)
to the 3.5mm mini jack connector AUDIO IN 2.
Note: Audio and video are completely independent circuits that switch as audio-follows-
video (AFV). There is no embedding or de-embedding of HDMI audio.
5. Connect the OUT HDMI connector to an HDMI acceptor (for example, an
LCD display).
6. Connect the AUDIO OUT 3.5mm mini jack connector to a stereo audio
acceptor (for example, a power amplifier).
7. Set the switching mode switches, as described in Section 5.
8. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.
