VM-4HC - 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-4HC 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-4HC - Overview

3 Overview

The Kramer VM-4HC is a high quality 1:4 HDMI distributor that accepts an HDMI

input and distributes the signal to up to four outputs simultaneously, thus making it

a versatile, reliable component in a video system. The VM-4HC distributes signals

having resolutions up to UXGA, including all HDTV formats.

In particular, the VM-4HC features:

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

HDTV compatibility and HDCP compliance

Simultaneous display of the video output on all of the four outputs (once they

are ready to display the output) upon power up

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

signal to travel longer distances

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

handling & processing algorithm ensures Plug and Play operation for HDMI

systems

EDID acquisition from a single output, all connected outputs (auto-mix) or a

default EDID

HDMI support for Deep Color, x.v.Color™, up to 7.1 Uncompressed Audio

Channels

3D pass thru

Active input & output LED Indictors

Compact size where 2 units can be rack mounted side-by-side in a 1U rack

space with the optional RK-1 adapter and a 5V DC mains power adapter

4 Connecting the VM-4HC

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

VM-4HC. After connecting your VM-4HC, connect its power and then

switch on the power to each device.

To connect the VM-4HC as illustrated in the example in Figure 2:

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

connector.

2. Connect the HDMI OUTPUT connectors to up to 4 HDMI acceptors as

follows:

As required. Up to four outputs can be connected. Not all outputs need to be connected.

OUTPUT 1 to display device 1 (for example, a plasma display)

OUTPUT 2 to display device 2 (for example, a plasma or LCD display)

OUTPUT 3 to display device 3 (for example, an LCD TV)

OUTPUT 4 to display device 4 (for example, a plasma display)

3. Connect the power adapter to the device and to the mains electricity (not

shown in Figure 2).

4. If required, acquire the EDID (see Section 4.1).

4.1 Acquiring the EDID

Initially the VM-4HC operates with the factory default EDID stored in the non-

volatile memory. The source reads the EDID from the device when the device is

plugged in or powered on.

The EDID can be acquired from:

One of the outputs

The default EDID

Up to four connected outputs using the Auto-mix Mode

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

VM-4HC - Connecting the VM-4HC

Repeatedly pressing the EDID SELECT button cycles through the EDID sources in

the following order:

If you attempt to acquire the EDID from an output that is not connected the default EDID is

acquired.

Output 1 (Output 1 LED lights)

Output 2 (Output 2 LED lights)

Output 3 (Output 3 LED lights)

Output 4 (Output 4 LED lights)

Default EDID (all LEDs light)

Auto-Mix EDID (the LEDs flash in a running sequence)

To store the selected EDID, press EDID READ as described in the following

example.

To cancel the EDID modification wait for a few seconds without touching any button.

Select the EDID from Output 3:

1. Press the EDID SELECT button repeatedly until OUTPUT 3 LED lights.

2. Press the EDID READ button.

When the LED stops flashing the EDID from Output 3 is stored at the input.

Pressing the EDID SELECT button briefly once causes the relevant LEDs to

indicate which EDID is stored at the input, as follows:

OUTPUT 1 LED flashes—the EDID from OUTPUT 1 was the last acquired

OUTPUT 2 LED flashes—the EDID from OUTPUT 2 was the last acquired,

and so on

All OUTPUT LEDs flash—the default EDID was the last acquired

All OUTPUT LEDs flash sequentially—the Auto-Mix EDID was the last

acquired

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
