2.1 Quick Start

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

Overview

3 Overview

fits into one vertical space of a standard 19” professional rack enclosure.

In particular, the VS-48H features:

•Up to 2.25Gbps bandwidth per graphic channel1

•Support for HDCP (High Definition Digital Content Protection)

•HDMI Support – HDMI (V1.4 with 3D, Deep Color, x.v.Color™,

Lip Sync)

•3D Pass-Through

•I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent

EDID handling & processing algorithm ensures Plug and Play

operation for HDMI systems

•Kramer reKlocking™ & Equalization Technology that rebuilds the

digital signal to travel longer distances

•A LOCK button to prevent unwanted tampering with the buttons on

the front panel

•Preset memory locations for quick access to common configurations

You can control the VS-48H using the front panel buttons, or remotely via:

•RS-232 serial commands transmitted by a PC, touch screen system or

other serial controller

•The Kramer infrared remote control transmitter

•A PC connected to the Ethernet port on the device via a LAN

3.1 Defining the EDID

The Extended Display Identification Data (EDID2

7.2

) is a data-structure

provided by a display to describe its capabilities to an HDMI source. The

EDID enables the VS-48H 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. See Section for

details of how to acquire the EDID.

1 Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions

2 Defined by a standard published by the Video Electronics Standards Association (VESA)

3.2 About HDMI

High-Definition Multimedia Interface (HDMI) is an uncompressed

all-digital1

In particular, HDMI:

audio/video interface, widely supported in the entertainment and

home cinema industry. It delivers the highest high-definition image and

sound quality. Note that Kramer Electronics Limited is an HDMI Adopter

and an HDCP Licensee.

•Provides a simple2interface 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

lengthy3

•Supports standard, enhanced, high-definition video, and multi-

channel digital audio

cable

•Transmits all ATSC HDTV standards and supports 8-channel digital

audio, with bandwidth to spare to accommodate future enhancements

and requirements

on a single cable

•Benefits consumers by providing superior, uncompressed digital

video quality via a single cable5

•Is backward-compatible with DVI (Digital Visual Interface)

, and user-friendly connector

•Supports CEC, 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, 2K and 4K), standard definition formats such as

NTSC or PAL, as well as 480p and 576.

3.3 About HDCP

The High-Bandwidth Digital Content Protection (HDCP) standard6

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

to-analog conversions

protects

digital video and audio signals transmitted over DVI or HDMI connections

between two HDCP-enabled devices to eliminate the reproduction of

2 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

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

4 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

5 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a

simple, cost-effective manner

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.

3.4 Recommendations for Best Performance

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VS-48H

away from moisture, excessive sunlight and dust

to avoid interference,

deterioration in signal quality due to poor matching, and elevated

noise levels (often associated with low quality cables).
