VM-2HD - 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-2HD 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-2HD - Overview

3 Overview

The VM−2HD is a high−performance distribution amplifier for HD−SDI signals. It

takes one input, provides reclocking and equalization and distributes the signal to

two identical outputs.

In particular, the VM-2HD features:

A range of up to 200m

Video bandwidthof 1.485Gbps that enables it to be used forstandarddefinition

and high definitionserial digital video signals (SD/HD-SDI)

Passing of digital information (embedded audio, Teletext, time code and so

on) during the vertical interval period

SMPTE 292M, 259M and 344M compliance and support for data rates of

143, 177, 270, 360, 540, 1483.5, 1485Mbps

Automatic, multi-rate, equalization and reclocking for losses typical with long

runs of 75co-axial cable up to 200m

LEDs indicating the SDI resolution

4 Connecting the VM-2HD

Always switch off the power to each device before connecting it to your

VM-2HD. After connecting your VM-2HD, connect its power and then

switch on the power to each device.

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

1. Connect an HD-SDI/SD-SDI video source (for example, a camera) to the

INPUT BNC connector.

2. Connect up to two video OUT BNC connectors to the appropriate

HD-SDI/SD-SDI video acceptors (for example, displays).

You do not have to connect both outputs.

3. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity (not shown in Figure 2).
