Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
Getting Started

application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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-211H2 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.

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.
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 Connecting the REMOTE Terminal Block
Connector on page 6.

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 input source 2: momentarily connect REMOTE IN2 to PIN G (ground).
Do not connect both the REMOTE IN1 and the REMOTE IN2 to PIN G simultaneously.
Figure 3: REMOTE Terminal Block Connector
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.
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:

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.
Reactivating or reconnecting the non-priority input has no effect on switching.
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.
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.
