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-88UT 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-88UT away from moisture, excessive sunlight and dust.

VS-88UT - Installing in a Rack
8
Installing in a Rack
This section provides instructions for rack mounting the VS-88UT. Before installing in a rack,
verify that the environment is within the recommended range:
Operation temperature –0to 40C (32 to 104F).
Storage temperature –-40to +70C (-40 to +158F).
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 still flow around the VS-88UT.
The VS-88UT is placed upright in the correct horizontal position.
You do not overload the circuit(s). When connecting the VS-88UT 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.
The VS-88UT 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 the VS-88UT:
1. Attach both rack ears to the VS-88UT:
Remove the screws from each side of the VS-88UT
(5 on each side), and replace them through the rack
ears.
2. Place the rack ears of the VS-88UT against the rack
rails and insert the appropriate screws (not provided)
through each of the four holes in the rack ears.
Some models, may feature built-in rack ears:
Detachable rack ears can be removed for desktop use.
Always mount the VS-88UT in the rack before connecting any cables or 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 available from our Web site
www.kramerav.com/downloads/VS-88UT.

Connecting the VS-88UT
This section describes how to:
Connect the Matrix Ports on page 9.
Connect the Controller Ports on page 11.
Always switch off the power to each device before connecting it to your VS-88UT. After
connecting your VS-88UT, connect its power and then switch on the power to each device.
Note that not all the ports are connected in the following example.
Connect the Matrix Ports
To connect the VS-88UT Matrix as illustrated in the example in Figure 3:
1. Connect the HDMI and HDBT sources:
An HDMI source (for example, a laptop) to the HDMI 1 IN connector .
Alternatively, you can connect the DVI connector on the DVD player to the HDMI
connector on the VS-88UT via a DVI-HDMI adapter.
An HDMI source (for example, a Blu-ray player) to the HDMI 4 IN connector .
An HDMI source (for example, a Blu-ray player) to the HDMI IN 8 HDMI
connector .
A transmitter (for example, the Kramer TP-590Txr) to the HDBT IN (8) RJ-45 port .
You can enable one of each HDMI and HDBT input pair (5, 6, 7 and 8) via the embedded
web pages, see Setting Input HDBT/HDMI Port Parameters on page 33.
2. Connect the audio sources:
An audio source (for example, the laptop audio output signal) to the AUDIO INPUT 1
balanced stereo analog audio 5-pin terminal block connector (1 to 4) .
A microphone to the AUDIO MIC 4 balanced audio 3-pin terminal block connector
(1 to 8) .
You can connect each AUDIO analog input 5-pin terminal block connector to either a
balanced stereo audio analog source or to up to two microphones via the web pages,
Setting Analog Audio Input Port Parameters on page 39.
An audio source (for example, an MP3 player) to the AUDIO INPUT 5 analog audio
3.5mm mini jack connector (5 to 8) .

3. Connect the HDMI and HDBT outputs:
The HDMI OUT 3 HDMI connector (1 to 4, 7 and 8) , to an HDMI acceptor (for
example, a display).
The OUT 6 (HDBT) RJ-45 port (5 to 6) to a receiver (for example, the Kramer
TP-590Rxr).
4. Connect the audio outputs:
The AUDIO LINE OUT (1 to 2) Terminal Block connector to a balanced audio
acceptor (for example, active speakers).
The POWER AMP OUT block connector to a pair of loudspeakers, by connecting
the left loudspeaker to the “L+” and the “L-” terminal block connectors, and the right
loudspeaker to the “R+” and the “R-” terminal block connectors.
Do not ground the loudspeakers.
5. Connect the IR ports:
HDBT IR IN 8 (5 to 8) 3.5mm mini jack to a room controller (for example, the
Kramer RC-74DL) to control a peripheral device, such as Blu-ray player that connects
to the transmitter that is connected to HDBT IN (8).
HDBT IR OUT 6 (5 to 6) 3.5mm mini jack to an IR controlled device (for example,
a Blu-ray player) So that it can be controlled by a controller that is connected to a
receiver that connects to the OUT 6 (HDBT) port.
6. Connect the USB ports:
A keyboard and a mouse to HDBT USB 2 ports .
The USB signal passes via HDBT IN to a transmitter (for example TP-590Txr) where
a laptop can be controlled.
A laptop to USB HOST 1 port .
A receiver (for example TP-590Rxr) connected to HDBT OUT controls this connected
laptop.
7. Connect RS-232 3-pin terminal blocks:
RS-232 HDBT DATA –Connect to a laptop to control peripheral devices that are
connected to transmitters/receivers that connect to the HDBT IN / HDBT OUT ports.
RS-232 CONTROL –Connect to a laptop to control VS-88UT.
8. Connect ETH ports:
CONTROL –Connect to a laptop to control VS-88UT.
DATA 1G –Connect to the Ethernet to pass data via the cloud.

For example, point an IR remote controller to the IR sensor to control a device that is
connected to a controller port.
2. Connect the IR OUT 2-pin terminal block connector (1 to 4) to an IR emitter and
attach the emitter to a controlled device (for example, a display).
3. Connect the GPI/O 2-pin terminal block connector (1 to 4) to an input/output device
(for example, a motion detector).
4. Connect the RELAY 2-pin terminal block connector (1 to 8) to a relay port (for
example, a controlled screen).
5. Connect the RS-232 3-pin terminal block connector (1 to 4) to a serially controlled
device (for example, a projector).
6. Connect the RS-485 3-pin terminal block connector to a controlled system (for
example, a lighting system).
7. Connect the K-NET 4-pin terminal block connector to a room controller (for example,
the Kramer RC-63DLN).
The room controller is powered via the 12V pin.
8. Set the TERM switches:
RS-485 TERM –Slide down for termination.
The first and the last units on the RS-485 line should be terminated (ON). Other units
should not be terminated (OFF).
K-NET TERM –Slide down for K-NET termination.
