VS-211HA - Getting Started

2 Getting Started

We recommend that you:

Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

Review the contents of this user manual

Go to http://www.kramerelectronics.com/support/product_downloads.asp

to check for up-to-date user manuals, application programs, and to check if

firmware upgrades are available (where appropriate).

2.1 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-211HA 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.

VS-211HA - Overview

3 Overview

The VS-211HA is a high-performance automatic standby switcher for HDMI video

and unbalanced stereo audio signals. The VS-211HA can be used as a manual

2x1 switcher or as an automatic switcher. The switcher either uses a priority input

or last connected input.

In priority switching, the signal automatically switches to the secondary input if the

primary signal is lost. If the primary signal reappears, the unit automatically

switches back to the primary input.

In last connected switching, the switcher automatically switches to the newly

introduced input.

In addition, the VS-211HA 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 display to source

DIP-switches for setting the switching mode (manual, auto priority, auto last

connected)

Contact closure remote control for manual operation

Signal auto detect

Parallel unbalanced stereo audio switching

Audio Return Channel (ARC)

No signal on both HDMI inputs triggers the output auto off, to allow displays

to enter sleep mode

Compact DigiTOOLS® size, three units can be rack mounted side-by-side in

a 1U rack space with the optional RK-3T rack adapter

4 Connecting the VS-211HA

Always switch off the power to each device before connecting it to your

VS-211HA. After connecting your VS-211HA, connect its power and

then switch on the power to each device.

To connect the VS-211HA, as illustrated in the example in Figure 2, do the

following:

1. Connect the HDMI input source 1 (for example, Blu-ray player 1) to the IN 1

HDMI connector.

2. Connect the HDMI input source 2 (for example, Blu-ray player 2) to the IN 2

HDMI connector.

3. Connect an unbalanced stereo audio source (for example, stereo player 1)

to the 3.5mm mini jack connector AUDIO IN 1.

4. Connect an unbalanced stereo audio source (for example, stereo player 2)

to the 3.5mm mini jack connector AUDIO IN 2.

Note: Audio and video are completely independent circuits that switch as audio-follows-

video (AFV). There is no embedding or de-embedding of HDMI audio.

5. Connect the OUT HDMI connector to an HDMI acceptor (for example, an

LCD display).

6. Connect the AUDIO OUT 3.5mm mini jack connector to a stereo audio

acceptor (for example, a power amplifier).

7. Set the switching mode switches, as described in Section 5.

8. Connect the 5V DC power adapter to the power socket and connect the

adapter to the mains electricity.
