3 Overview
The Kramer VP-6A is a high performance distribution amplifier for computer
graphics (UXGA) video and audio signals. The VP-6A accepts:
One computer graphics input: provides correct buffering and isolation,
and distributes the signal to six outputs on 15-pin HD connectors, and one
twisted pair output
A stereo audio input signal: either
1
an unbalanced stereo audio input
signal on a 3.5mm mini jack, or a balanced stereo audio input signal on a
5-pin terminal block connector. The VP-6A outputs 12 stereo audio
signals simultaneously: six unbalanced stereo audio signals on 3.5mm
mini jacks, and six balanced stereo audio signals on 5-pin terminal block
connectors. If the selected audio input is unbalanced, it is converted to
balanced stereo audio; if the selected audio input is balanced, it is
converted to unbalanced stereo audio
The VP-6A can:
Power the receiver over the same CAT5 cable
Be used with the TP-122 XGA / Audio Line Receiver (converting the
CAT5 signal to XGA, stereo analog and S/PDIF digital audio outputs) or
with the TP-120 XGA Line Receiver (converting the CAT5 signal to an
XGA output)
In addition, the VP-6A features:
A video bandwidth of 500MHz that ensures transparent operation at all
graphics resolutions
Switches on the underside for ID Bit control and sync polarity
Front panel controls for UXGA equalization, as well as left and right
audio level controls
A transmission range of more than 300 ft. (more than 100 meters) over
UTP cabling

3.1 About the Power Connect Feature
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter— to either the transmitter or the receiver.
The other unit is fed via the cable connecting between the
transmitter/receiver. The Power Connect feature applies as long as the cable
can carry power. The distance does not exceed 50 meters on standard CAT5
cable, for longer distances, heavy gauge cable should be used
1
.
For a CAT5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded
twisted pair (STP) cable is used. However, the shield itself does create a
capacitance that degrades the frequency response of the machines. For shorter
distances, of 50m or so, shielded twisted pair (STP) cable is preferred because
it provides protection from interference (degradation is not apparent).
For long range applications, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far
away from electric cables, motors and so on, which are prone to create
electrical interference.
3.3 Recommendations for Achieving the Best Performance
Achieving the best performance means:
Connecting 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)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality, and positioning your Kramer VP-6A
away from moisture, excessive sunlight and dust

5 Installing the VP-6A on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
5 to 65% RHL, non-condensing
-20 to +70 Deg. Centigrade
5 to 95% RHL, non-condensing
Operating humidity range
Storage temperature range
Storage humidity range
When installing on a 19" rack, avoid hazards by taking
care that:
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.
Attach both ear brackets to the
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.
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:
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 (you can
download it at:
http://www.kramerelectronics.com)




In some models, the front panel
may feature built-in rack ears
Once rack mounted, enough air will still flow around the
machine.
The machine is placed straight in the correct horizontal
position.
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.
The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention
and that you use only the power cord that is
supplied with the machine.
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,

The example in Figure 3 illustrates how to output a computer graphics signal
(and audio) from a computer to up to six local monitors, as well as how to
transmit it over UTP cabling to a TP-122 XGA / Audio Line Receiver.
To connect the VP-6A and a TP-122, do the following:
1. Connect a computer graphics source (for example, a computer) to the
INPUT HD15F connector and to the UNBAL. AUDIO IN 3.5mm mini
jack, for example, using a Kramer C-GMA/GMA cable
1
. Press the IN
SELECT button
2
.
2. Connect the OUTPUT HD15F connectors to up to
3
six acceptors (for
example, Local Display 1 to Local Display 6).
3. Connect up to
3
12 stereo audio outputs
4
, that is, up to six:
Unbalanced stereo audio OUT 3.5mm mini jacks, and
Balanced
5
stereo audio 5-pin terminal block connectors (see section 6.1)
4. Connect
6
the CAT5 RJ-45 LINE OUT connector
7
to the LINE IN RJ-45
connector on a Kramer CAT5 receiver, such as the TP-122 unit.
5. Connect the power cord
8
to the VP-6A (not illustrated in Figure 3).
6. On the VP-6A:
Adjust
9
the UXGA cable compensation equalization level and/or the
audio level, if required
Set the ID BIT switches 4 and 11 on the underside to ON (by sliding
them to the left). This would enable a notebook or laptop (if connected
instead of a computer) to output an UXGA signal to an external VGA
monitor
If necessary, slide the VS and HS switches to the right to output
1 XGA HD15M +Audio jack to XGA HD15M +Audio jack (not supplied). The complete list of Kramer cables is on our Web
site at http://www.kramerelectronics.com. Alternatively, you can connect an XGA source to the XGA INPUT HD15F
connector, and a separate audio source to the UNBAL. AUDIO IN
2 Alternatively, connect a computer graphics source to the INPUT HD15F connector, and a balanced stereo audio source to the
BAL. AUDIO INPUT 5-pin terminal block connector, and release the IN SELECT button
3 When not all outputs are required, connect only the outputs that are required and leave the other outputs unconnected
4 Note, that if the selected audio input is unbalanced, it is converted to balanced stereo audio; if the selected audio input is
balanced, it is converted to unbalanced stereo audio
5 By wiring the balanced outputs as unbalanced (see Figure 5) you can output 12 unbalanced stereo audio outputs
6 Via UTP cabling, with a range of more than 300ft (>100m): see section 6.1
7 The TP-122 (or TP-120) may be powered via this connector (instead of via the 12VDC external supply)
