VM-114H - 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-114H 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-114H - Overview

3 Overview

The high-quality VM-114H 2x Input 1:4 HDMI DA 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 identical HDMI outputs.

In particular, the VM-114H features:

A maximum data rate of 6.75 Gbps (2.25Gbps per graphic channel) (HDMI),

4.95Gbps (1.65Gbps per graphic channel) (DGKat)

Reading and storing, 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

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

handling & processing algorithm ensures Plug and Play operation for HDMI

systems

3D Pass-through, Deep Color (on the HDMI input), x.v.Color™ and

uncompressed audio channels (Dolby TrueHD, DTS-HD)

HDCP compliance

LEDs indicating the selected input and active output

IR remote control

12V DC supply and is housed in a Kramer desktop enclosure

The VM-114H supports ranges 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-114H - 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 60m (197ft) of each other. The Power Connect™ feature

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

60m on standard TP cable. (Heavier gauge cable may be used to extend the

Power Connect™ range).

Warning: Using an incorrectly wired TP cable will cause permanent

damage to the device!
