VM-1H4C –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-1H4C away from moisture, excessive sunlight and

dust

This equipment is to be used only inside a building. It may be

connected only 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 Kramer Electronics input power wall

adapter that is provided with the unit.

Warning:

Disconnect the power and unplug the unit from the wall

before installing

VM-1H4C –Getting Started

2.3 Shielded Twisted Pair

Kramer engineers have developed special shielded 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), and the Kramer

BC-DGKat7a23 (CAT 7a 23 AWG) cables. These specially built cables

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

The VM-1H4C supports a range of up to:

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

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

between the first and last devices being cumulative and limited to 500m.

2.4 About the Power Provision Feature

Only the VM-1H4C needs to be connected to a power source when the devices

are within 90m (270ft) of each other –the VM-1H4C can provide power to the

receiver over the TP cable. This feature applies as long as the cable can carry

power and the distance does not exceed 90m on standard TP cable. For longer

distances, heavier gauge cable should be used (standard TP cable is still suitable

for the video/audio transmission, but not for feeding the power at these distances).

2.5 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-1H4C –Overview

3 Overview

The high quality VM-1H4C is a distribution amplifier for HDMI, IR and bidirectional

RS-232 signals over TP (Twisted Pair) cable. It reclocks and equalizes the input

signal and distributes it to four TP outputs simultaneously.

More specifically, the VM-1H4C:

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

Can read and store the default EDID or the EDID block from one or a mix of

the output display devices in non-volatile memory, so it can then provide the

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

Displays the video output on all of the four outputs at the same time (once

they are ready to display the output) upon power up

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

EDID handling & processing algorithm ensures Plug and Play operation for

HDMI systems

Supports 3D Pass-through, x.v.Color™ and uncompressed audio channels

(Dolby TrueHD, DTS-HD)

Is HDCP compliant

Features LEDs indicating a live input and the active output

Has a remote IR 3.5mm mini jack that supports bidirectional IR signals

Supports bidirectional, RS-232 serial data

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

The VM-1H4C encodes the HDMI, IR and RS-232 signals and transmits them over

TP cable to a compatible receiver (for example, the Kramer TP-574 HDMI/RS-232/

IR Line Receiver).

Warning:

Using a TP cable that is incorrectly wired may cause

permanent damage to the device

To connect the VM-1H4C as illustrated in the example in Figure 2:

1. Connect the HDMI source, (for example, a DVD player) to the Input (HDMI)

connector.

2. Connect the TP RJ-45 outputs to up to four TP acceptors, (for example,

TP-574).
