KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The VS-44HD is a true 4x4 matrix switcher1 for standard definition / high
definition SDI signals that lets you simultaneously route any of the four
inputs to any or all of the four outputs. It can be used as a 4x4 SD/HD-SDI
matrix switcher or as a dual-link 2x2 SD/HD-SDI Matrix switcher. The
VS-44HD features:
Input and output signals on BNC connectors and selector buttons that
automatically light up in different colors—green, when the VS-44HD
detects a ‘standard definition’ signal, or blue, when it detects a ‘high
definition’ signal
Reclocking and equalization on each input
The ability to switch genlocked video signals according to timing of the
GENLOCK reference input. Switching according to the Bi-level or
Tri-level Genlock input according to SMPTE RP-1682
Factory reset that lets you reset the machine to its original default state
The storing and recalling of setups, a Take button for the execution of
multiple switches all at once, and a front panel lock
The VS-44HD is housed in a 19" 1U rack mountable enclosure and is fed
from a 100-240 VAC universal switching power supply. Control is via the
front panel buttons, infrared remote control transmitter, and/or remotely, by
RS 232 or RS 485 serial commands transmitted by a touch screen system, PC,
or other serial controller, as well as ETHERNET or remote contact closure for
forced operation.
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VS-44HD
away from moisture, excessive sunlight and dust

Figure 1, Table 1, and Table 2 define the VS-44HD 4x4 SD/HD-SDI Matrix
Switcher.
1 Switching is implemented during the vertical interval period according to the SMPTE RP-168 standard, when using
synchronized SDI sources
2 The sources must be genlocked to the GENLOCK input in order to switch cleanly

Installing on a Rack
5 Installing on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing in a Rack
Before installing in a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5° to +45° C (41° to 113° F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20° to +70° C (-4° to 158° F)
Storage humidity range 5 to 95% RHL, non-condensing
To rack-mount a machine:
1. Attach both ear brackets to the
How to Rack Mount
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
When installing on a 19" rack, avoid hazards by taking
CAUTION!!
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions

Connecting Your VS-44HD
6 Connecting Your VS-44HD
This section describes how to connect the VS-44HD as a:
4x4 SD/HD SDI Matrix Switcher, see section 6.1
Dual-Link 2x2 SD/HD-SDI Matrix Switcher, see section 6.2
6.1 Connecting Your VS-44HD 4x4 SD/HD-SDI Matrix Switcher
You can use your VS-44HD to switch one of the four standard definition / high
definition SDI inputs to any or all of the four standard definition / high
definition SDI outputs, as the example in Figure 2 shows.
To connect the VS-44HD 4x4 SD/HD-SDI Matrix Switcher, do the following1:
1. Connect up to four SDI sources to the SDI INPUT BNC connectors (for
example, an HD/SD SDI camera to input 1 and an HD video player to input 4).
2. Connect the SDI OUTPUT BNC connectors to up to2 four SDI acceptors
(for example, output 1 to a Preview monitor, and output 4 to an HD SDI
mixer).
3. Set the dipswitches (see section 6.4).
4. As an option3, connect:
A Genlock source to the GENLOCK BNC connector
The LOOP BNC connector to the GENLOCK connector of the next
unit in the line, and release the TERM button for looping4
5. Connect a PC and/or controller (if required), to the:
RS-232 port (see section 6.5), and/or
RS-485 port (see section 6.6), and/or
ETHERNET connector (see section 6.9)
6. As an option3, connect a remote contact closure switch (refer to section 6.10)
7. Connect the power cord5.
1 Switch OFF the power on each device before connecting it to your VS-44HD. After connecting your VS-44HD, switch on
its power and then switch on the power on each device
2 When only one output is required, connect that output, and leave the other outputs unconnected
3 Not illustrated in Figure 2
4 Pushed in terminates the input. Release when the input extends to another unit
5 We recommend that you use only the power cord that is supplied with this machine
