2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VS-211HDxl is a high-performance automatic standby switcher for
SD/HD-SDI and 3G HD-SDI video signals. The VS-211HDxl
automatically switches to the secondary input whenever the primary video
signal is interrupted. If the primary signal reappears, the unit automatically
switches back to the primary input.
In addition, the VS-211HDxl features:
•Maximum data rate of up to 2.97Gbps
•Multi-standard operation – SMPTE 259M, 292M and 424M
compliance and support for data rates of 270Mbps, 1483.5Mbps,
1485Mbps and 2970Mbps
•A DEFAULT INPUT switch for selecting the default SDI master
source signal
•Contact closure remote control for forced operation
•Active switching and has flexible sync detection and
reconstruction circuitry
To achieve the best performance:
•Use only good quality connection cables1to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VS-211HDxl away from moisture, excessive sunlight and dust

This section describes how to:
•Connect the VS-211HDxl (see section 5.1)
•Select the default master source signal (see section 5.2)
•Connect the REMOTE connector (see section 5.3)
5.1 Connecting the VS-211HDxl 3G HD-SDI Automatic Standby
Switcher
To connect the VS-211HDxl, as illustrated in the example in Figure 2, do the
following1:
1. Connect SDI input source 1 (for example, SDI video camera 1) to the IN 1
BNC connector.
2. Connect SDI input source 2 (for example, SDI video camera 2) to the IN 2
BNC connector.
3. Connect SDI acceptor 1 (for example, SDI display 1) to the OUT 1 BNC
connector.
4. Connect SDI acceptor 2 (for example, SDI display 2) to the OUT 2 BNC
connector.
5. Set the DEFAULT INPUT switch to whichever input is the master input, as
described in section 5.2.
6. If needed, connect remote switches to the REMOTE IN 1 and IN 2
terminal block connectors, as described in section 5.3.
7. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity.

5.2 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-211HDxl
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 and IN 1
reactivates, IN 1 reactivates
•If IN 1 is active while IN 2 is the default input and IN 2
reactivates, IN 2 reactivates

5.3 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 switch1
(see Figure 3).
•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
INPUT 1
Attach PIN IN2 to
PIN G to activate
INPUT 2

is removed
