3.1 About the WP-27 / WP-28
The Kramer WP-27 and the WP-28 constitute a twisted pair transmitter and
receiver system for component/composite
1
or Y/C video, as well as stereo
analog / S/PDIF audio signals. Each unit can power or be powered by the other
unit over the same CAT5 cable.
The WP-27 transmitter converts the selected
2
video and audio signals into a
twisted pair signal and the WP-28 receiver decodes that signal back to its initial
stage. The WP-27 accepts either a component video, composite video or s-
Video source. The selected video source, as well as the selected audio source
3
is
transmitted to the WP-28, which outputs that source accordingly
4
.
If CV-Y/C is selected, the WP-27 accepts a CV
5
or Y/C
6
signal
7
and
transmits it over the CAT5 cable to the CV or Y/C output on the WP-28
receiver
If component video is selected
8
, the component video signal
7
is transmitted
over the CAT5 cable to the COMP output on the WP-28 receiver
If the ANALOG stereo audio source is selected via the AUDIO button, the
WP-27 converts it to a digital 48kHz 24 bit signal which is transmitted,
together with the video signal, over the CAT5 cable to the WP-28 receiver
If S/PDIF (digital audio) is selected via the AUDIO button, it is transmitted
together with the video signal over the CAT5 cable to the WP-28 receiver
1 Either s-Video or composite video (both inputs cannot be connected simultaneously)
2 Via two INPUT select buttons letting you choose the video signal input and the audio signal input
3 The audio signal is outputted to both outputs simultaneously
4 The WP-27 and WP-28 do not perform any video signal format conversion. A composite video source would need to be
routed to a composite video output or an s-Video source would need to be routed to an s-Video output. Similarly, a
component video source would need to be routed to a component video output
5 By connecting only a CV input and releasing the Y/C-CV COMP VIDEO INPUT button
6 By connecting only a Y/C input and releasing the Y/C-CV COMP VIDEO INPUT button
7 And audio signal
8 By pressing the Y/C-CV COMP VIDEO INPUT button

3.2 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
2
.
For a CAT5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
1 Also known as Y, B-Y, R-Y or YUV
2 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

3.3 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 non apparent).
For a long range application, 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.
3.4 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 WP-27 and/or
WP-28 in a location free from moisture and away from excessive sunlight
and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

5 Connecting the WP-27 / WP-28
When configuring the WP-27 / WP-28 CAT5 Transmitter and Receiver system,
you can choose to transmit one of the three video signals to the receiver: a
component video signal, or a composite video signal or an
s-Video signal. You can connect either a composite video source or an
s-Video signal, as well as a component video signal and use the video input
selector button to choose the desired signal to transmit to the receiver.
In the example illustrated in Figure 5, the WP-27 / WP-28 CAT5 Transmitter
and Receiver system is set up to transmit a component video signal (for
example, for high quality home cinema).
To connect the Transmitter and Receiver system, as shown in the example
illustrated in Figure 5, do the following
1
:
1. On the WP-27, connect a:
Component video source (for example, a component video player), to
the Y, C B /P B , and C R /P R RCA VIDEO INPUT connectors
A digital audio source
2
(for example, the audio signal of the component
video player), to the S/PDIF AUDIO INPUT RCA connector
2. On the WP-27,press
3
the VIDEO INPUT selector button and release
4
the
AUDIO INPUT selector button.
3. On the WP-28, connect the:
Y, C B /P B , and C R /P R RCA VIDEO INPUT connectors to a component
video aceptor (for example, a plasma display)
S/PDIF AUDIO INPUT RCA connector to a digital audio acceptor (for
example, a receiver and speakers)
4. On the WP-28,press
5
the VIDEO OUTPUT selector button.
5. Connect the CAT5 OUT connector of the WP-27 to the CAT5 IN
connector of the WP-28, via UTP cabling (maximum range of up to 300ft
(100m)).
6. On both
6
the WP-27 and the WP-28, connect the 12V DC power adapter
to the power socket and connect the adapter to the mains electricity (not
shown in Figure 5).
1 You can transmit one of three video signals to the receiver: a component video signal, a composite video signal or an s-
Video signal. The receiver outputs this signal only
2 Alternatively, you can also connect an analog audio signal and select it via the AUDIO INPUT selector button
3 Thus selecting the component video input
4 Thus selecting the digital audio input
5 Thus selecting the component video output
6 If you cannot connect the power to both the WP-27 and WP-28, you can just connect the power to the WP-28
