VM-22H - 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 VM-22H 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.

VM-22H - Overview

3 Overview

The VM−22H is a distribution amplifier for HDMI signals. The unit reclocks and

equalizes one of two selectable input signals and distributes it to two identical

outputs.

In particular, the VM-22H features:

A maximum data rate of 6.75Gbps (2.25Gbps bandwidth per graphic

channel

I-EDIDPro™ Kramer Intelligent EDID Processing™, an intelligent EDID

handling and processing algorithm that ensures Plug and Play operation for

HDMI systems

Kramer Equalization & re-Klocking™ Technology that rebuilds the digital

signal integrity to travel longer distances

3D pass-through

HDMI support for 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.

VM-22H - Connecting the VM-22H

4 Connecting the VM-22H

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

VM-22H. After connecting your VM-22H, connect its power and then

switch on the power to each device.

To connect the VM-22H as illustrated in the example in Figure 2:

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).

VM-22H - Acquiring the EDID

5 Acquiring the EDID

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.

Initially, the VM-22H operates with the factory default EDID. This lets you connect

the power before connecting one of the acceptors or sources.

You can acquire the EDID from:

One output (the relevant output illuminates)

The default EDID (both output LEDs blink)

Two connected outputs, the auto-mix mode (both output LEDs illuminate)

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.

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

of EDID was last acquired. If the:

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-Mix EDID 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.
