VM-2HDCPxl - 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 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-2HDCPxl 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-2HDCPxl - Overview

3 Overview

The Kramer VM-2HDCPxl is an HDCP (High-Bandwidth Digital Content

Protection) compatible 1:2 distribution amplifier for DVI-D (Digital) signals. Since

high-resolution DVI signals are very sensitive to cable quality and to PCB layout,

the VM-2HDCPxl uses a uniquely designed PCB which includes all buffering,

conditioning and amplifying circuitry to provide two high-level output signals.

In particular, the VM-2HDCPxl features:

Distribution of signals having resolutions up to WUXGA, including all HDTV

formats

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

Support for the DDWG DVI 1.0 standard

A built-in re-clocking block that re-generates the DVI signal, so that several

units may be cascaded

Reading and storage, in non-volatile memory, of the EDID block from one of

the outputs, so it can then provide the EDID information to the DVI source

even if the display device is not connected

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

handling and processing algorithm that ensures Plug and Play operation for

HDMI systems

Three DVI-I connectors, which are compatible with all types of DVI cables

A cost-effective solution for distributing the TMDS signals used for DVI, and

uses state-of-the-art line drivers on both outputs

4 Connecting the VM-2HDCPxl

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

VM-2HDCPxl. After connecting your VM-2HDCPxl, connect its power

and then switch on the power to each device.

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

1. Connect a computer graphics source to the INPUT connector.

2. Connect the OUTPUT connectors to one or both DVI acceptors, as follows:

You do not have to connect both outputs.

OUTPUT 1 connector to DVI acceptor 1 (for example, a display)

OUTPUT 2 connector to DVI acceptor 2 (for example, a projector)

3. Connect the 5V DC power adapter (wall transformer) to the 5V DC socket

and connect the transformer to the mains electricity.

4. Acquire the EDID (see section 4.1).

4.1 Acquiring the EDID

Initially, the VM-2HDCPxl operates with the factory default EDID. This lets you

connect the power before connecting one of the acceptors or the source.

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

You can acquire the EDID from:

One output (the relevant output illuminates)

The default EDID (both output LEDs flash)

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.
