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.

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

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.
