2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer highperformance, 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

In addition, the VS-211H 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 source to display
A DEFAULT INPUT switch for selecting the default HDMI master source signal
Contact closure remote control for forced operation

Connect the VS-211H (see Section 4.1
Select the default master source signal (see Section
Connect the REMOTE connector (see Section 4.3
4.1 Connecting the VS-211H
i
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
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) i
Do not connect both the REMOTE IN1 and the REMOTE IN2 to PIN G simultaneously
