VM-114H4C - 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 Kramer VM-114H4C 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.

before installing

2.3 Recycling Kramer Products

The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC

aims to reduce the amount of WEEE sent for disposal to landfill or incineration by

requiring it to be collected and recycled. To comply with the WEEE Directive,

Kramer Electronics has made arrangements with the European Advanced

Recycling Network (EARN) and will cover any costs of treatment, recycling and

recovery of waste Kramer Electronics branded equipment on arrival at the EARN

facility. For details of Kramer’s recycling arrangements in your particular country

go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

VM-114H4C - Overview

3 Overview

The high quality VM-114H4C is a switcher/distribution amplifier for HDMI and TP

(Twisted Pair) signals. It reclocks and equalizes one of two selectable input signals

and distributes it to four TP outputs.

In particular, the VM-114H4C:

Supports up to 4.95Gbps (1.65Gbps bandwidth per graphic channel)

(DGKat)

Can read and store in non-volatile memory the default EDID or the EDID

block from one or a mix of the output display devices, so it can then provide

the EDID information to the source even if the display device is not

connected

The EDID acquired is a weighted average of all the connected outputs. For example, if

several displays with different resolutions are connected to the outputs, the acquired

EDID supports all the resolutions, as well as other parameters included in the EDID.

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

EDID handling & processing algorithm ensures Plug and Play operation for

HDMI systems

Supports HDMI 3D Pass-through, Deep Color, x.v.Color™ and

uncompressed audio channels (Dolby TrueHD, DTS-HD)

Is HDCP compliant

Features LEDs indicating the selected input and active output

Supports IR remote control and has a remote IR 3.5mm mini jack

Is 12V DC fed and is housed in a Kramer Desktop enclosure

The VM-114H4C supports a range of:

Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on shielded

BC-DGKat524 cable

Up to 90m (295ft) at 1080i, or up to 70m (230ft) at 1080p on shielded

BC-DGKat623 cable

Up to 100m (330ft) at 1080i or up to 90m (295ft) at 1080p on shielded

BC-DGKat7a23 cable

VM-114H4C - Overview

You can daisy-chain up to six devices with the maximum overall distance between

the first and last devices being cumulative and limited by the cable type used.

3.1 Using Twisted Pair Cable

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

digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the

Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23

(CAT 7a 23 AWG cable). These specially built cables significantly outperform

regular CAT 5 / CAT 6 / CAT 7a cables.

3.2 About the Power Connect™ Feature

The Power Connect™ feature here means that only one unit in a system, the

transmitter or receiver, needs to be connected to a power source when the

devices are within 90m (270ft) of each other. The Power Connect™ feature

applies as long as the cable can carry power and the distance does not exceed

90m on standard TP cable. (Heavier gauge cable may be used to extend the

Power Connect™ range).

Warning:

Using a TP cable that is incorrectly wired can cause

permanent damage to the device!
