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  
connected to other equipment that is installed inside a building.

Using the VS-211H  
This section describes how to:

Select the default master source signal (see Section 4.2)  
Connect the REMOTE connector (see Section 4.3)  
4.1

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  
i

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.

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

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
