Getting Started

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

5 Using the VS-211HDxl

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.

1 Switch OFF the power on each device before connecting it to your VS-211HDxl. After powering up your VS-211HDxl,

switch on the power on each device

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

Using the VS-211HDxl

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

1 Note that the connection should be permanent, since the VS-211HDxl reverts to an automatic switcher when the connection

is removed
