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-211H away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be

VS-211H - Using the VS-211H
4 Using the VS-211H
This section describes how to:
Connect the VS-211H (see Section 4.1)
Select the default master source signal (see Section 4.2)
Connect the REMOTE connector (see Section 4.3)
4.1 Connecting the VS-211H
Always switch off the power to each device before connecting it to your
VS-211H. After connecting your VS-211H, connect its power and then
switch on the power to each device.
To connect the VS-211H, as illustrated in the example in Figure 2, do the following:
1. Connect the IN 1 HDMI connector to the HDMI input source 1 (for example,
DVD player 1).
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 4.2.
5. If needed, connect the remote switches to the REMOTE IN 1 and IN 2
terminal block connectors, as described in Section 4.3.
6. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.

4.2 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

4.3 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 switch (see Figure 3).
Note that the connection should be permanent, since the VS-211H reverts to an automatic
switcher when the connection is removed.
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

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.
