VS-44FO – 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/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 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 VS-44FO 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.
2.2 Safety Instructions
Caution:
There are no operator serviceable parts inside the unit
Warning:
Use only the power cord that is supplied with the unit
Warning:
Do not open the unit. High voltages can cause
electrical shock! Servicing by qualified personnel only
Warning:
Disconnect the power and unplug the unit from the wall
before installing

2.3 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/.

VS-44FO – Overview
3 Overview
The VS-44FO is a high-performance matrix switcher for fiber optic signals. It can
switch any or all inputs to any or all outputs simultaneously.
In particular, the VS-44FO features:
A maximum data rate of up to 3Gbps, enabling it to be used for standard
definition, high-definition and the new 3G high definition serial digital video
signals (3G HD-SDI)
A range of up to 40km (depending on the SFP module used)
HDTV compatibility
A single mode SFP (small form-factor pluggable) SDI fiber optic connector
for the input and the output
A looping analog sync for genlock –bi-level and tri-level sync compatible
Selectable sync signal termination
Automatic reclocking and equalization
Active input reporting where each input LED on the front panel automatically
lights when the unit detects a video signal on that input
Multiple memory locations that store multiple switches as presets (salvos) to
be recalled and executed when needed
A Take button that executes multiple switches all at once
Vertical interval switching that synchronizes either to an external reference
or to the incoming video in compliance with SMPTE RP-168
Flexible control options including front panel, RS-232 (K-router™
Windows®-based software is included), RS-485, Ethernet and IR
Laser Class I acc. 21 CFR 1040 and Class 1 per IEC 60825-1 compliance
The VS-44FO is housed in a 19" 1U rack-mountable enclosure, and is fed from a
100-240V AC universal switching power supply.

The unit can be controlled using the front panel buttons or:
Using an RC-IR3 infrared remote control transmitter (included)
Remotely, by RS-232 or RS-485 serial commands transmitted by a PC,
touch screen system, or other serial controller
Via the Ethernet
By default, the VS-44FO is controlled using the Kramer 3000 protocol (see Section
6.1.9 for details of how to switch to Protocol 2000 and Section 9for the relevant
protocol commands).
3.1 Defining the SFP
An SFP is a small form-factor pluggable transceiver that is a compact, hot-
swappable, input/output transceiver used in data communication and
telecommunications networks. The SFP interfaces between communication
devices like switches, routers and fiber optic cables, and performs conversions
between optical and electrical signals.
The SFP transceiver is specified by the SFP Transceiver Multisource Agreement
(MSA), which was developed and is followed by different transceiver
manufacturers. SFP transceivers have a wide range of detachable interfaces to
multimode/single-mode fiber optics that allows users to select the appropriate
transceiver according to the required optical range for the network. The VS-44FO
supports use of non-MSA (SFP Transceiver Multisource Agreement) video
modules and MSA communication modules.
The optical transceiver modules are engineered for exceptional performance in the
presence of SDI pathological patterns. The transceivers feature best-in-class
optical receiver sensitivity for SMPTE 259M, SMPTE 344M, SMPTE 292M and
SMPTE 424M serial rates, to provide superior optical link budget and robustness.
