2 VM-2HDxl - 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

•Use Kramer high-performance, high-resolution cables

Go to http://www.kramerelectronics.com 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 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−2HDxl away from moisture, excessive sunlight

and dust

Caution: 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-2HDxl - Overview 3

3 Overview

The VM−2HDxl is a high−performance distribution amplifier for 3G HD−SDI

signals. The unit takes one input, provides reclocking and equalization and

distributes the signal to two identical outputs.

In particular, the VM-2HDxl features:

•Cable equalization up to 300m

300m for SD signals; 200m for 1.5GHz HD signals; 100m for 3GHz HD signals

(measured with Kramer BC-1X 1 Coax RG-6 Super High-Resolution Cable).

•One input and two identical outputs on BNC connectors

•A data rate of up to 3Gbps, that enables it to be used for standard definition, high

definition and the 3G high definition serial digital video signals (SDI, HD-SDI and

3G HD-SDI)

•HDTV compatibility

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

on) during the blanking period

•SMPTE 292M, 259M, 344M and 424M compliant with data rates of

270Mbps, 540Mbps, 1483.5Mbps, 1485Mbps and 2970Mbps

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

runs of 75Ωco-axial cable up to 300m

•LEDs indicating the SDI resolution (SD or HD)

4 Connecting the VM-2HDxl

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

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

then switch on the power to each device.

To connect the VM-2HDxl, as the example in Figure 2 illustrates, do the following:

1. Connect an HD-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

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).
