VM-4HDT - 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.kramerav.com/downloads/VM-4HDT 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 neighbouring electrical appliances that may adversely

influence signal quality

Position your Kramer VM-4HDT 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-4HDT - Overview

3 Overview

The Kramer MegaTOOLS®VM-4HDT is a high-quality 1:4 HDMI to HDBT DA that

takes one HDMI input, equalizes and reclocks the signal and distributes it to four

identical HDBT outputs. The VM-4HDT distributes signals having resolutions up to

4Kx2K and including WUXGA and 1080p.

In particular, the VM-4HDT features:

A maximum data rate of 10.2Gbps (3.4Gbps per graphic channel)

HDMI support for 3D, Deep Color, x.v.Color™, Lip Sync, HDMI

Uncompressed Audio Channels, Dolby TrueHD, DTS-HD, CEC (only for OUT

HDCP compliance (note that sources that support HDCP will output HDCP

protected content)

Kramer Equalization & re-Klocking™ Technology that rebuilds the digital

signal integrity to travel longer distances

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

handling and processing algorithm that ensures Plug and Play operation for

HDMI systems

A default EDID for fast and efficient connection of the unit

The default EDID feature lets you connect the VM-4HDT without having to connect a

display to the output

Support for EDID Designer via the USB port

3D pass-through

A 5V DC power source

A MegaTOOLS®sized enclosure. two devices can be mounted in a 1U rack

space using the optional RK-T2B adapter

The VM-4HDT supports a range of up to 70m (230ft) at 2K resolutions and 40m

(130ft) at 4K resolutions (on shielded BC-HDKat6a cable).

3.1 About HDBaseT™ Technology

HDBaseT™ is an advanced all-in-one connectivity technology (supported by the

HDBaseT Alliance). It is particularly suitable in the ProAV –and also the home –

environment as a digital networking alternative, where it enables you to replace

numerous cables and connectors by a single LAN cable used to transmit, for

example, uncompressed full high-definition video, audio, IR, as well as various

control signals.

The products described in this user manual are HDBaseT certified.

3.2 Using Twisted Pair Cable for HDBT

Kramer engineers have developed special twisted pair cables to best match our

digital twisted pair products; BC−HDKat6a (CAT 6 23 AWG cable) significantly

outperforms regular CAT 5 / CAT 6 cables.

We strongly recommend that you use shielded twisted pair cable.
