Getting Started

2.1 Quick Start

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

Overview

3 Overview

The Kramer VM-2HDCP 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-2HDCP uses a uniquely designed PCB which includes

all buffering, conditioning and amplifying circuitry to provide two high-level

output signals.

In particular, the VM-2HDCP:

Distributes signals having resolutions up to UXGA, including all HDTV

formats

Has a bandwidth of 1.65GHz

Supports the DDWG DVI 1.0 standard

Consists of a built-in re-clocking block that re-generates the DVI signal,

so that several units may be cascaded

Can read and store, in non-volatile memory, 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

Stores a default EDID for fast and efficient connection of the unit

Has three DVI-I connectors, which are compatible with all types of DVI

cables

Is a cost-effective solution for distributing the TMDS signals used for

DVI, and uses state-of-the-art line drivers on both outputs

3.1 About HDCP

The High-Bandwidth Digital Content Protection (HDCP) standard

, protects

digital video and audio signals transmitted over DVI or HDMI connections

between two HDCP-enabled devices to eliminate the reproduction of

copyrighted material. To protect copyright holders (such as movie studios)

from having their programs copied and shared, the HDCP standard provides

for the secure and encrypted transmission of digital signals.

1 Note that Kramer Electronics Limited is an HDCP Licensee, see http://www.digital-cp.com/list/

2 EDID is Extended Display Identification Data

3 The default EDID feature lets you connect the VM-2HDCP without having to connect a display to the output

4 Developed by Intel

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

3.2 Defining EDID

The Extended Display Identification Data (EDID

) is a data-structure,

provided by a display, to describe its capabilities to the source. The EDID

enables the VM-2HDCP 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.

3.3 Recommendations for Best Performance

Achieving the best performance means:

Connecting 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)

Avoiding interference from neighboring electrical appliances and

positioning your VM-2HDCP away from moisture, excessive sunlight

and dust

Caution – No operator-serviceable parts inside unit.

Warning – Use only the Kramer Electronics input power

wall adapter that is provided with this unit

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.

# Feature Function

1 12V DC +12V DC connector for powering the unit

2 OUTPUT1 DVI Connector Connect to the DVI acceptor 1

3 OUTPUT2 DVI Connector Connect to the DVI acceptor 2

4 INPUT DVI Connector Connects to the DVI source

5 INPUT LED Lights when the input is active; blinks when the input is not valid

6 OUT 1 LED LED lights when OUTPUT 1 is connected and active; LED blinks

when selecting the EDID (see section 5.1)

7 OUT 2 LED LED lights when OUTPUT 2 is connected and active; LED blinks

when selecting the EDID (see section 5.1)

8 ON LED Lights when the unit is powered

9 EDID Button Press to read the EDID of the selected display (see section 5.1)

5 Connecting a VM-2HDCP 1:2 DVI Distributor

To connect the VM-2HDCP as illustrated in the example in Figure 4, do the

following:

1. Connect a DVI source (for example, a host computer) to the INPUT

connector.

2. Connect the OUTPUT connectors

to one or both DVI acceptors, as

follows:

OUTPUT 1 connector to DVI acceptor 1 (for example, a projector)

OUTPUT 2 connector to DVI acceptor 2 (for example, a display)

3. Connect the 12V DC power adapter (wall transformer) to the 12V DC

socket and connect the transformer to the mains electricity.

4. Acquire the EDID (see section 5.1).

1 Both outputs do not need to be connected

5.1 Acquiring the EDID

Initially, the VM-2HDCP operates with the factory default EDID

. This lets

you connect the power before connecting either of the acceptors or the source.

You can acquire:

The Default EDID (both output LEDs blink)

The EDID from One Output (the relevant output illuminates)

You can also acquire the Clone EDID which copies the EDID data from the

acceptor bit-by-bit.

5.1.1 Acquiring / Changing the EDID

You can work with the default EDID or acquire or change an EDID via one

of the connected outputs. Use the EDID Setup button to acquire the output

EDID information.

To acquire or change the EDID of a new output display:

1. Connect the power supply.

The ON LED lights.

2. Connect the new output display device.

3. Press and hold the EDID button for more than three seconds and release.

The INPUT LED blinks and the OUT 1 LED and OUT 2 LED blink

alternately.

4. Press the EDID button again when the appropriate OUT LED lights, that

is, to copy the EDID from the display connected to the DVI:

OUT 1 connector, press the EDID button when the OUT1 LED is on

OUT 2 connector, press the EDID button when the OUT2 LED is on

In either case, the VM-2HDCP copies the EDID from the display. If no

display is connected to the selected DVI output, the default EDID will

be chosen.

Note that during the EDID setup, the respective OUT LED blinks. When that

output is connected, that OUT LED illuminates

1 The VM-2HDCP reads the EDID, which is stored in the non-volatile memory
