Review the contents of this user manual
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 neighbouring electrical appliances that may adversely
influence signal quality
Position your VS-211H2 away from moisture, excessive sunlight and dust

VS-211H2 - Connecting the VS-211H2
Always switch off the power to each device before connecting it to
your VS-211H2. After connecting your VS-211H2, connect its power
and then switch on the power to each device.
4 Connecting the VS-211H2
To connect the VS-211H2, as illustrated in the example in Figure 2, do the
following:
1. Connect the INPUT 1 connector to HDMI source 1 (for example, a Blu-ray
player).
2. Connect the INPUT 2 connector to HDMI source 2 (for example, a laptop
computer graphics source 4K@60 UHD).
3. Connect the OUTPUT connector to an HDMI acceptor (for example, a
4K@60 UHD projector).
4. If manual switching is needed, connect contact closure (pushbutton)
switches to the REMOTE terminal block see Section 4.1.

Do not connect both the REMOTE IN1 and the REMOTE IN2
to PIN G simultaneously
4.1 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 momentary contact closure switches
(pushbuttons) (see Figure 3).
To force input source 1: momentarily connect REMOTE IN1 to PIN G
(ground)
To force I input source 2: momentarily connect REMOTE IN2 to PIN G
(ground)
Figure 3: REMOTE Terminal Block Connector
Note: The contact closure setting remains in effect until the selected source device
is disconnected or the VS-211H2 is powered off. All automatic switching is
overridden.
4.2 Setting the VS-211H2 DIP-Switches and Operation
When active input sources are connected to IN 1 and IN 2, the VS-211H2
switches in accordance with the DIP-switch settings on the rear of the unit.

Figure 4: DIP Switches
The settings and switching behavior can be set in any of the following ways:
4.2.1 Priority Setting: DIP 1 is Set to ON (Down)
In this switching mode, if a source is present on the “priority input”, then this
source is switched to the output.
DIP 2 defines the priority input:
When set to OFF (up), INPUT 1 is the priority input
When set to ON (down), INPUT 2 is the priority input.
Note: Reactivating or reconnecting the non-priority input has no effect on
switching.
4.2.2 Last Connected Setting: DIP 1 is Set to OFF (Up)
In this switching mode, whenever a source is connected to an input which, until
then, did not have a valid source connected to it, that input is switched to the
output. (The reactivating or reconnecting of any source makes it the new “Last
Connected” source).
DIP 2 has no effect in this switching mode
4.2.3 Manual Override: Using the REMOTE switches
Controlling via the remote contact closure pushbuttons (see Figure 3) overrides all
DIP-switch settings and automatic switching until the manually selected source
disconnects, becomes inactive or the VS-211H2 is powered off.
