Overview

3 Overview

The VS-21H-IR is a high quality switcher for HDMI signals that accepts two

HDMI inputs—letting you select either HDMI input using a switch located on

the panel—and routes the selected HDMI input signal to the HDMI output. In

particular, the VS-21H-IR:

•Supports up to 2.25Gbps bandwidth per graphic channel1

•Is 12V DC fed

•Can be controlled remotely

3.1 About HDMI

High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital2

In particular, HDMI

audio/video interface, widely supported in the entertainment and home cinema

industry. It delivers the highest high-definition image and sound quality. Note that

Kramer Electronics Limited is an HDMI Adopter and an HDCP Licensee.

•Benefits consumers by providing superior, uncompressed digital video

quality via a single cable7

•Is backward-compatible with DVI (Digital Visual Interface)

currently used in A/V systems is reduced

5 HDMI technology has been designed to use standard copper cable construction at up to 15m

6 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to

support Dolby 5.1 audio and high-resolution audio formats

player) and the digital television, enabling new functionality such as

automatic configuration and one-button play

HDMI has the capacity to support existing high-definition video formats (720p,

1080i, and 1080p/60), standard definition formats such as NTSC or PAL, as well

as 480p and 576p.

3.2 Recommendations for Best Performance

To achieve the best performance:

•Connect only good quality connection cables, thus avoiding 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 and position your

VS-21H-IR away from moisture, excessive sunlight and dust

5 Connecting the VS-21H-IR 2x1 HDMI Switcher

To connect the VS-21H-IR, as the example in Figure 2shows, do the following1

1. Connect up to two HDMI sources to the INPUT connectors, using the

Kramer HDMI cables: INPUT 1 connector to HDMI source 1 (for example,

DVD Player 1) and INPUT 2 connector to HDMI source 2 (for example,

DVD Player 2).

2. Connect the OUTPUT connector to the HDMI acceptor (for example, a

plasma display), using the Kramer HDMI cable.

3. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity.

4. Press the SELECT button2to choose which HDMI input to route to the

output. The SELECT button toggles between INPUT 1 and INPUT 2,

lighting the IN 1 LED when INPUT 1 is selected, or the IN 2 LED when

IN 2 is selected.

Figure 2: Connecting a VS-21H-IR 2x1 HDMI Switcher

to switch INPUT 1 or 2 to the output.

Before doing so, set it to work with the VS-21H-IR by assigning a GROUP

number.

1. Point the remote control transmitter at the remote receiver (item 10 in

Figure 1/ Table 1) and press the GROUP key.

2. Press key 11.

This sets and saves the group number.

To switch INPUT 1 or 2 to the output via the remote control transmitter, press key

1 or 2.

6 Operating the VS-21H-IR 2x1 HDMI Switcher

This section describes how to operate the VS-21H-IR, using the SELECT button.

The VS-21H-IR functions in two modes: the PC mode2(see section 6.1) and the

DVD mode (see section 6.2).

6.1 Working in the PC Mode

This section describes how to acquire / change the EDID (see section 6.1.1) and

how to reset the default EDID (see section 6.1.2) when working in the PC mode.

6.1.1 Acquiring / Changing the EDID

You can work with the default EDID or acquire / change the EDID.

To acquire or change the EDID:

1. Connect the new output display device.

If no output display device is connected to the output, the default EDID

will be stored in the non-volatile memory.

2. Connect the power while keeping the SELECT button pressed until the

LEDs start to blink.

3. To change the EDID and store it in the non-volatile memory of:

INPUT 1, release the SELECT button while the IN 1 LED blinks

INPUT 2, release the SELECT button while the IN 2 LED blinks

1 The setup parameters for the remote control transmitter are as follows: router number = 1 (default); group number = 11,

single digit mode (default), video (default). For further details, see the RC-IR2 user manual

2 The default

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Operating the VS-21H-IR 2x1 HDMI Switcher

Both INPUT 1 and 2, release the SELECT button while both the IN 1

and the IN 2 LEDs light

4. When a certain input—INPUT 1 or INPUT 2—is selected the EDID

information comes directly from the display. When the input is not

selected, the VS-21H-IR uses the virtual EDID stored in the non-volatile

memory.

6.1.2 Resetting the Default EDID

To reset the default EDID, do the following:

1. Disconnect the power.

2. Disconnect the output cable.

3. Connect the power while keeping the SELECT button pressed until the

desired INPUT LED blinks.

6.2 Working in the DVD Mode

In the DVD mode, an unselected input will not receive any EDID data. The

selected input will receive the EDID data from the display device.

6.2.1 Toggling from the DVD mode to the PC mode

To toggle from the DVD mode to the PC mode:

1. Press the SELECT button for a few seconds until both INPUT LEDs blink.

2. Release the SELECT button.

The new EDID data is stored in the non-volatile memory.

If an output display device is connected to the output, the EDID from that

output display device will be stored in the non-volatile memory.

If no output display device is connected to the output, the default EDID

will be stored in the non-volatile memory.

6.2.2 Toggling from the PC mode to the DVD mode

To toggle from the PC mode to the DVD mode:

1. Press and hold the SELECT button until both INPUT LEDs light

continuously without blinking.

2. Release the SELECT button.

The VS-21HDMI-IR switches to DVD mode.
