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.
2.2 Safety Instructions
Caution:

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.

4.1 Connecting the REMOTE Terminal Block Connector
If DIP 1 is set ON to manual you can switch the active input by using contact
closure switches. To do this, connect the appropriate REMOTE input terminal
block connector pins to a contact closure switch (see Figure 3).
To select IN 1: Momentarily connect REMOTE IN1 to PIN G (ground)
To select IN 2: Momentarily connect REMOTE IN2 to PIN G (ground)
Do not connect both the REMOTE IN1 and the REMOTE IN2
to PIN G simultaneously
Momentarily

VS-211HA - Operating the VS-211HA
5 Operating the VS-211HA
The VS-211HA works in three modes:
Manual mode (see Section 5.1)
Automatic mode (see Section 5.2)
Override mode (see Section 5.3)
5.1 Using the Manual Mode
In manual mode the VS-211HA only switches when the remote contact closure
switches are momentarily pressed. If you switch to an inactive input source, the
output is blank.
Note: A source is considered active only when there is an active clock signal coming from the
source.
To set manual mode:
Slide the AUTO/MANUAL DIP 1 down to MANUAL (see Figure 1)
Select the required port manually by pressing the switches connected to the
terminal block
5.2 Using the Automatic Mode
Automatic mode uses automatic signal detection to determine the device’s
behavior during switching. Automatic mode has two further modes: Priority mode
and Last connected mode.
In Automatic/Priority mode, Input 1 has the higher priority
If two sources are connected and active, Input 1 is sent to the output
If Input 1 becomes inactive, Input 2 is sent to the output
If Input 1 returns to activity, Input 1 is sent to the output
For example, a sports bar has an AV system that displays live sports action on Input 1
while commercials loop on Input 2. If the game is interrupted, commercials automatically
display until the live action returns.

To set Automatic/Priority mode:
Slide AUTO/MANUAL DIP 1 up to AUTO and LAST/PRIORITY DIP 2 down
to PRIORITY
In Automatic/Last mode, the last connected input is sent to the output
If Inputs 1 and 2 are active when the VS-211HA is powered on, Input 1 is
sent to the output (as the priority input)
If Input 2 is disconnected, Input 1 is still sent to the output
If Input 2 is reconnected, Input 2 is sent to the output
For example, a salesman connected to Input 1 displays a presentation on the AV system
of a boardroom. A second salesman arrives, connects to Input 2 and continues with
his/her presentation.
To set Automatic/Last Connected mode:
Slide AUTO/MANUAL DIP 1 up to AUTO and LAST/PRIORITY DIP 2 up to
LAST
5.3 Using the Override Mode
Override mode is used while the VS-211HA is in either Priority or Last connected
automatic mode. Pressing either of the contact closure switches:
Forces the chosen input, if it is active, to be sent to the output
If the forced signal is inactive for 10 seconds, the VS-211HA returns to auto
mode
If the forced signal is lost, the VS-211HA reverts to its selected mode
For example, a sales manager, connected to Input 1, displays a presentation on the AV
system of a boardroom. A salesman arrives and wants to connect to Input 2 without
interrupting the manager. They press the Input 1 contact closure switch to allow Input 2 to
connect without interrupting Input 1.
