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).
