KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

3 Overview

The Kramer

VM-4DH is a high quality 1:4 HDMI DisplayPort Distributor

that accepts an HDMI input, equalizes and reclocks the data,

and distributes the signal to two DisplayPort (DP) outputs and two HDMI outputs.

The

VM-4DH features:

One HDMI input, two HDMI outputs, two DisplayPort outputs, four output status LEDs, an active input status LED, as well as EDID read and select buttons

Up to 2.7Gbps bandwidth per graphic channel

A maximum resolution of 2560x1600 pixels and a total maximum bandwidth of 10.8Gbps over four lanes

Kramer re-Klocking™ and Equalization Technology, which rebuilds the digital signal to travel longer distances

Enhanced EDID (Extended Display Identification Data) - the unit can store and recall an EDID setting in non-volatile memory from either the default EDID or a connected output, allowing convenient and reliable connection to the source

Compliance to HDCP

High-resolution and rich colors and transports audio and multiple video streams

Worldwide Power Supply – 100-240V AC

A standard 19” rack-mount size - 1U. Rack "ears" are included

3.1 About DisplayPort

DisplayPort (DP) is a new digital display interface standard for the PC industry. It delivers the highest resolutions and sound quality.

In addition, DisplayPort:

Provides a simple interface between a PC and a display, projector or TV

Supports 1 to 4 data pairs ("lanes") at a transfer rate of 1.62Gb or 2.7Gb per second

Has a maximum length of 15 meters for video transmission, at a resolution of 1080p/60Hz and 3 meters for full bandwidth transmission

Video specs include a video path that supports 6 to 16 bits per color channel, a maximum resolution of 2560x1600 pixels and a total maximum bandwidth of 10.8Gbps over four lanes

Is backward-compatible with HDMI, DVI (Digital Visual Interface) and

VGA, via an appropriate adapter

Version 1.1 supports HDCP (see section 3.3)

3

Overview

Supports two-way communication over its auxiliary channel between the video source (for example, a PC) and the digital display, enabling new functionality such as automatic configuration and one-button play

Replaces the interface needed between the PC and an external display, as well as the low voltage differential signaling (LVDS) interface in notebook computers, monitors, to connect to LCD panels

3.2 About HDMI

High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital industry. It delivers the highest high-definition image and sound quality.

1 audio/video interface, widely supported in the entertainment and home cinema

In particular, HDMI

2

:

Provides a simple

3

interface 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 lengthy

4

cable

Supports standard, enhanced, high-definition video, and multi-channel digital audio

5

on a single cable

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 cable

6

, and user-friendly connector

Is backward-compatible with DVI (Digital Visual Interface)

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

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

2 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI licensing LLC

3 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

4 HDMI technology has been designed to use standard copper cable construction at up to 15m

5 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

6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner

KRAMER: SIMPLE CREATIVE TECHNOLOGY

3.3 About HDCP

High-Bandwidth Digital Content Protection (HDCP) standard

1

protects digital video and audio signals transmitted over DisplayPort, HDMI or DVI 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, encrypted transmission of digital signals.

3.4 Defining EDID

The Extended Display Identification Data (EDID

2

) 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-4DH 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.

3.5 Recommendations for Best Performance

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-4DH away from moisture, excessive sunlight and dust

Installing the VM-4DH in a Rack

5 Installing the VM-4DH in a Rack

This section describes what to do before installing in a rack and how to rack mount.

Before Installing in a Rack

Before installing in a rack, be sure that the environment is within the recommended range:

Operating temperature range +5º to +45º C (41º to 113º F)

Operating humidity range 10 to 90% RHL, non-condensing

Storage temperature range -20º to +70º C (-4º to 158º F)

Storage humidity range 5 to 95% RHL, non-condensing

How to Rack Mount

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

CAUTION !!

When installing in a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.

2. Once rack mounted, enough air will still flow around the machine.

3. The machine is placed straight in the correct horizontal position.

4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.

5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

8

2. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note that:

In some models, the front panel

may feature built-in rack ears

Detachable rack ears can be removed for desktop use

Always mount the machine in the rack before you attach any cables or connect the machine to the power

If you are using a Kramer rack adapter kit (for a machine that is not

19"), see the Rack Adapters user manual for installation instructions

6.3 Acquiring EDID

The

VM-4DH initially operates with the default EDID. This means that you can

turn ON the power before connecting any of the acceptors or the source.

You can acquire the EDID from:

The default EDID, see section 6.3.1

A connected output, see section 6.3.2

6.3.1 Acquiring the Default EDID

To acquire the default EDID, do the following:

1. Press the SELECT button, as required, to reach a disconnected output.

The selected output LED blinks.
