VS-44HN - 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 VS-44HN 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.

2.2 Safety Instructions

Caution:

There are no operator serviceable parts inside the unit

Warning:

Use only the power cord that is supplied with the unit

Warning:

Do not open the unit. High voltages can cause

electrical shock! Servicing by qualified personnel only

Warning:

Disconnect the power and unplug the unit from the wall

before installing

VS-44HN - Overview

3 Overview

The VS-44HN is a high quality 4x4 matrix switcher for HDMI signals. It reclocks

and equalizes the signals and can route any input to any or all outputs

simultaneously.

In particular, the VS-44HN features:

Up to 6.75Gbps data rate (2.25Gbps per graphics channel)

Suitable for resolutions up to UXGA and 1080p at 60Hz

Support for HDCP (High Definition Digital Content Protection)

HDMI Support –HDMI (3D, Deep Color, x.v.Color™, Lip Sync)

3D pass-through

Support for up to 7.1 multi-channel audio

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

handling & processing algorithm ensures Plug and Play operation for HDMI

systems

Kramer reKlocking™ and 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

Support for Kramer Protocol 2000 and Protocol 3000

You can control the VS-44HN 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

An external remote IR receiver (optional), see Section 3.3

VS-44HN - Overview

3.1 About Fast Switching

Older display devices required a longer time between the loss of one digital signal

and the introduction of another, as well as a physical disconnection of the

interconnecting cable in order to be able to detect and adjust to the new video

attributes and parameters. Normal switching, therefore, introduced a 5V signal

disconnection along with a delay in switching. Many newer display devices,

however, are now capable of “on-the-fly” switching.

Depending on the display device in use, the VS-44HN allows for fast switching

(minor reset and the connection kept alive) and extra fast switching (no reset and

the connection kept alive). Using the fast and extra fast switching modes allows for

fraction-of-a-second switching times when using high performance display devices

or when using a scaler on the video output.
