This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VS-211H is a high-performance automatic standby switcher for HDMI
1.3 video signals. The VS-211H automatically switches to the secondary
input whenever the primary video signal is interrupted. If the primary signal
reappears, the unit automatically switches back to the primary input.
In addition, the VS-211H features:
•A maximum data rate of up to 2.25Gbps
•HDTV compatibility
•HDCP and HDMI compliance
•A DEFAULT INPUT switch for selecting the default HDMI master
source signal
•Contact closure remote control for forced operation
•Active switching
To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VS-211H away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

•Select the default master source signal (see section 5.2)
•Connect the REMOTE connector (see section 5.3)
5.1 Connecting the VS-211H Automatic HDMI Standby Switcher
To connect the VS-211H, as illustrated in the example in Figure 2, do the
following1
1. Connect HDMI input source 1 (for example, DVD player 1) to the IN 1
HDMI connector.
:
2. Connect HDMI input source 2 (for example, DVD player 2) to the IN 2
HDMI connector.
3. Connect HDMI acceptor (for example, an LCD display) to the OUT HDMI
connector.
4. Set the DEFAULT INPUT switch to whichever input is the master input, as
described in section 5.2.
5. If needed, connect the remote switches to the REMOTE IN 1 and IN 2
terminal block connectors, as described in section 5.3.
6. Connect the 5V DC power adapter to the power socket and connect the

5.2 Selecting the Default Master Source Signal
When active input sources are connected to IN 1 and IN 2, the DEFAULT
INPUT switch setting determines the default master input source.
•If the master input signal is not detected, the VS-211H
automatically activates the standby input:
If IN 1 is the default input and it fails, IN 2 activates
If IN 2 is the default input and it fails, IN 1 activates
•If the master input reactivates while the standby input is active,
the unit automatically switches back to the master input:
If IN 2 is active while IN 1 is the default input, when IN 1
reactivates, it is switched to the output
If IN 1 is active while IN 2 is the default input, when IN 2
reactivates, it is switched to the output

5.3 Connecting the REMOTE Terminal Block Connector
Regardless of the default input switch setting, you can force the switching
of the active input by remote control. To do this, connect the appropriate
REMOTE input terminal block connector pins to a contact closure switch1
Figure 3
(see ).
•To force IN 1: connect REMOTE IN1 to PIN G (ground)
•To force IN 2: connect REMOTE IN2 to PIN G (ground)
Do not connect both the REMOTE IN1 and the REMOTE IN2
to PIN G simultaneously
Attach PIN IN1 to
PIN G to activate
INPUT 1
Attach PIN IN2 to
PIN G to activate
INPUT 2
Figure 3: REMOTE Terminal Block Connector
Note: The contact closure setting remains in effect until an event occurs
such as changing the default input switch or connecting or attaching an
HDMI device.
1 Note that the connection should be permanent, since the VS-211H reverts to an automatic switcher when the connection is
removed
