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 www.kramerav.com/downloads/VS-44UHD to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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 neighbouring electrical appliances that may adversely influence
signal quality.
• Position your Kramer VS-44UHD 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.

VS-44UHD – Installing in a Rack
6
Installing in a Rack
This section provides instructions for rack mounting VS-44UHD. Before installing in a rack,
verify that the environment is within the recommended range:
• Operation temperature – 0 to 40C (32 to 104F).
• Storage temperature – -40 to +70C (-40 to +158F).
• Humidity – 10% to 90%, RHL non-condensing.
When installing on a 19" rack, avoid hazards by taking care that:
▪ It is located within recommended environmental conditions. Operating ambient
temperature of a closed or multi-unit rack assembly may exceed ambient room
temperature.
▪ Once rack mounted, there is enough air flowing around VS-44UHD.
▪ VS-44UHD is placed upright in the correct horizontal position.
▪ You do not overload the circuit(s). When connecting VS-44UHD to the supply circuit,
overloading the circuits may 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.
▪ VS-44UHD is earthed (grounded) and connected only to an electricity socket with
grounding. Pay particular attention when electricity is supplied indirectly (for example,
when the power cord is not plugged directly into the wall socket but to an extension cable
or power strip). Use only the supplied power cord.
To rack-mount VS-44UHD:
1. Attach both rack ears to VS-44UHD:
Remove the screws from each side of
VS-44UHD (3 on each side), and replace them
through the rack ears.
2. Place the rack ears of VS-44UHD against the
rack rails and insert the appropriate screws (not
provided) through each of the four holes in the
rack ears.

Connecting the VS-44UHD
Always switch off the power to each device before connecting it to your VS-44UHD. After
connecting your VS-44UHD, connect its power and then switch on the power to each
device.
Although this connecting example shows only several inputs and outputs that are
connected, you can connect all the inputs and outputs simultaneously.
To connect the VS-44UHD as illustrated in the example in Figure 3, do the following:
1. Connect up to four video sources to the HDMI inputs (from INPUT 1 to INPUT 4). For
example, connect:
▪ A laptop to the INPUT 1 and 4 HDMI connectors.
▪ Blu-ray players to the INPUT 2 and 3 HDMI connectors.
2. Connect the four video HDMI outputs (from OUTPUT 1 to OUTPUT 4) to up to four
acceptors. For example, connect the:
▪ OUTPUT 1 HDMI connector to a projector.
▪ OUTPUT 2, OUTPUT 3 and OUTPUT 4 HDMI connectors each to a display.
3. Connect the power cord .
We recommend that you use only the power cord that is supplied with this machine.
4. Connect the:
▪ ETHERNET port to a system controller.
▪ RS-232 3-pin terminal block connector to a system controller.
5. If required, connect the 5V/2A USB port to a device to charge it.
