Getting Started

2.1 Quick Start

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

Overview

3 Overview

The high quality VM-22H is a switcher/distribution amplifier for HDMI

signals. It reclocks and equalizes one of two selectable input signals and

distributes it to two identical outputs. In particular, the VM-22H features:

•Up to 2.25Gbps bandwidth per graphic channel1

•I-EDIDPro™ Kramer Intelligent EDID Processing™, an

intelligent EDID handling and processing algorithm that ensures

Plug and Play operation for HDMI systems

•3D pass-through

•HDMI Support – HDMI (V.1.4 with Deep Color, x.v.Color™, Lip

Sync, CEC)

•HDCP compliance

•Selected input and active output LED indicators

The VM-22H is 5V DC fed and is housed in a DigiTOOLS®enclosure.

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.

•Provides a simple

4interface between any audio/video source, such

as a set-top box, DVD player, or A/V receiver and video monitor,

such as a digital flat LCD/plasma television (DTV), over a single

lengthy5

•Supports standard, enhanced, high-definition video, and multi-

channel digital audio

cable

1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions

on a single cable

2 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-

to-analog conversions

3 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI

licensing LLC

4 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables

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

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

•Transmits all ATSC HDTV standards and supports 8-channel

digital audio, with bandwidth to spare to accommodate future

enhancements and requirements

•Benefits consumers by providing superior, uncompressed digital

video quality via a single cable1

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

, and user-friendly connector

•Supports two-way communication between the video source (such

as a DVD 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), as well as standard definition formats such as

NTSC or PAL.

3.2 Defining EDID

The Extended Display Identification Data (EDID2

3.3 Recommendations for Best Performance

) is a data-structure,

provided by a display, to describe its capabilities to a graphics card (that is

connected to the display’s source). The EDID enables the VM-22H to

“know” what kind of monitor is connected to the output. The EDID

includes the manufacturer’s name, the product type, the timing data

supported by the display, the display size, luminance data and (for digital

displays only) the pixel mapping data.

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 VM-22H away from moisture, excessive sunlight and dust

1 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a

simple, cost-effective manner

2 Defined by a standard published by the Video Electronics Standards Association (VESA)

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Using the VM-22H 2x1:2 HDMI Switcher/DA

5.1 Connecting the VM-22H 2x1:2 HDMI Switcher/DA

To connect the VM-22H, as the example in Figure 2shows, do the

following1

1. Connect the HDMI source (for example, a DVD player) to the HDMI

IN 1 connector.

2. Connect the HDMI source (for example, a DVD player) to the HDMI

IN 2 connector.

3. Connect the HDMI OUT connectors to up to two HDMI acceptors, as

follows:

HDMI OUT 1 connector to an LCD TV

HDMI OUT 2 connector to a plasma display

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

adapter to the mains electricity.

5. Press the EDID SETUP button to acquire or change the EDID information

(see section 5.2).

Figure 2: Connecting a VM-22H 2x1:2 HDMI Switcher/DA

1 Switch OFF the power on each device before connecting it to your VM-22H. After connecting your VM-22H, switch on its

power and then switch on the power on each device

Using the VM-22H 2x1:2 HDMI Switcher/DA

5.2 Acquiring the EDID1

Initially, the VM-22H operates with the factory default EDID

You can acquire the EDID from:

. This lets

you connect the power before connecting one of the acceptors or sources.

•One Output (the relevant output illuminates)

•The Default EDID (both output LEDs blink)

•Two Connected Outputs, the Auto-mix Mode3

When pressing the EDID SETUP button briefly, the OUT LEDs indicate

which type of EDID was last acquired. If the:

(both output LEDs

illuminate)

•OUT 1 LED illuminates, the OUT 1 EDID is stored in the non-

volatile memory

•OUT 2 LED illuminates, the OUT 2 EDID is stored in the non-

volatile memory

•OUT 1 and OUT 2 LEDs blink, the Default EDID is stored in the

non-volatile memory

•OUT 1 and OUT 2 LEDs illuminate, the Auto-Mix3EDID is

stored in the non-volatile memory

To acquire the EDID, do the following:

1. Connect the power.

2. Connect the output or outputs from which you want to acquire the EDID.

3. Press and hold the EDID SETUP button to select the desired EDID.

The OUT LEDs illuminate in the following cycle: OUT 1, OUT 2, both

blink (Default) and both illuminate (Auto-mix3).

4. Release the button when reaching the desired set up4

The EDID is now acquired.

1 This is usually done only once, when the machine is being set up in an installation. Once acquired, the EDID is saved in

non-volatile memory and further acquisition is not necessary

2 The VM-22H reads the EDID, which is stored in the non-volatile memory

3 The EDID acquired is a weighted average of all the connected outputs. For example, if several displays with different

resolutions are connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included

in the EDID

4 If you set the machine to acquire the EDID from an output that is not connected, the Default EDID will be acquired
