Introduction
1 Introduction
Welcome to Kramer Electronics (since 1981): a world of unique, creative and
affordable solutions to the infinite range of problems that confront the video,
audio and presentation professional on a daily basis. In recent years, we have
redesigned and upgraded most of our line, making the best even better! Our
350-plus different models now appear in 8 Groups1, which are clearly defined
by function.
Congratulations on purchasing your Kramer WP-211DS wall plate2, which is
ideal for any system requiring automatic computer and presentation routing
for computer graphics signals (up to UXGA and higher). The package
includes the WP-211DS wall plate and this user manual3.

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.

Overview
The other unit is fed over the same CAT5 cable. The Power Connect feature
applies as long as the CAT5 cable is heavy gauge cable (that is, it can carry
power). The distance does not exceed 50 meters on standard cable.
For a distance of 100 meters, separate power supplies must be connected to
the transmitter and to the receiver simultaneously, unless using heavy gauge
CAT5 cable.
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 will give better results. 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 etc., which are prone to create electrical
interference.
3.3 About the WP-211DS
Your Kramer WP-211DS Wall Plate—available in 4 versions: one for
Belgium, one for Germany, one for England (and the rest of Europe), and one
for the USA— is a high performance 2x1 automatic switcher for computer
graphics and stereo audio signals. The WP-211DS detects the presence of the
active XGA-type input signal from either IN 1 (the default) or IN 2, and
automatically routes it to the acceptor connected to the rear panel XGA OUT
and the AUDIO OUT connectors. In addition, the WP-211DS:
ñ
With its video bandwidth exceeding 260MHz, ensures transparent
operation at the highest resolutions
Automatically switches the stereo audio signal with the video signal
(audio-follow-video) when switching the active input to the output
Includes a DEFAULT SELECT switch for selecting the computer
graphics master (default) source signal

3.4 Recommendations for Achieving the Best Performance
Achieving the best performance means:
ñ
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)
ñ
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality, and positioning your WP-211DS away
from moisture, excessive sunlight and dust

5.3 Connecting the WP-211DS
To connect your WP-211DS, do the following:
1. Connect a computer graphics (master) source to the XGA INPUT 1 HD15F
connector and to the AUDIO IN 1 3.5mm mini jack, for example, using a
Kramer C-GMA/GMA cable1.
2. Set the DEFAULT SELECT switch to IN 1 (the factory preset default) or
IN 2, as section 5.4 describes.
3. Connect a second computer graphics source to the XGA INPUT 2 HD15F
connector and to the AUDIO IN 2 3.5mm mini jack, for example, using a
Kramer C-GMA/GMA cable1.
4. Connect an additional display to the LOOP HD15F connector (optional).

5.4 Operating using the Default Master Source Signal Selection
The DEFAULT SELECT switch is factory preset to IN 1 and the WP-211DS
will detect the presence of the master source signal at the XGA INPUT 1
connector. If you connect active sources to both the XGA INPUT 1 and the
XGA INPUT 2 connectors, the source at the XGA INPUT 1 connector takes
priority over the source at the XGA INPUT 2 connector and it is routed to the
XGA OUT and the AUDIO OUT connectors (audio follows the video).
You can change the default so that the WP-211DS automatically detects an
active source signal from XGA INPUT 2, by setting the DEFAULT SELECT
switch to IN 2. When active, the source at the XGA IN 2 connector takes
priority over the source at the XGA INPUT 1 connector and it is routed to the
XGA OUT and the AUDIO OUT connectors (audio follows the video).
If the WP-211DS detects:
ñ
No signal1 at the XGA INPUT 1 input (when INPUT 1 is selected as the
default), the WP-211DS routes the signal from the source at XGA INPUT 2
and AUDIO IN 2 to the XGA OUT and the AUDIO OUT connectors.
Similarly, if the WP-211DS detects no signal at the XGA INPUT 2 input
(when IN 2 is selected as the default), the WP-211DS routes the signal from
the source at XGA INPUT 1 and AUDIO IN 1 to the XGA OUT and the
AUDIO OUT connectors
ñ
A signal from the XGA source at XGA INPUT 1 input (when IN 1 is
selected as the default), while routing the signal from the XGA source at XGA
INPUT 2, the WP-211DS will reroute the signal from the XGA source at
XGA INPUT 1 and AUDIO IN 1 to the XGA OUT and the AUDIO OUT
connectors. Similarly, if the WP-211DS detects a signal from the XGA source
at XGA INPUT 2 input (when IN 2 is selected as the default), while routing
the signal from the XGA source at XGA INPUT 1, the WP-211DS will
reroute the signal from the XGA source at XGA INPUT 2 and AUDIO IN 2 to
the XGA OUT and the AUDIO OUT connectors
ñ
No signal at all (that is, when there is no active input from a source at
XGA INPUT 1 or at XGA INPUT 2), the WP-211DS will still route XGA
INPUT 2 and AUDIO IN 2 to the XGA OUT and AUDIO OUT connectors,
and continue to examine XGA INPUT 1 input (when IN 1 is selected as the
default), switching back to it when it detects a valid signal. Similarly, if the
WP-211DS detects no signal at all (when IN 2 is selected as the default), it
will still route XGA INPUT 1 and AUDIO IN 1 to the XGA OUT and AUDIO
OUT connectors, and continue to examine XGA INPUT 2 input, switching
back to it when it detects a valid signal
1 Perhaps no source is connected, or that source is connected but its power is OFF

5.5 Connecting the REMOTE Connector
You can force the routing of one of the 2 inputs to the XGA output by remote
control. To do so, connect the appropriate REMOTE input terminal block
connector pins to a dry contact switch1. For example, as Figure 6 illustrates, to
route REMOTE IN 1 to the XGA output, connect PIN 1 to the Ground. To route
REMOTE IN 2 to the XGA output, connect PIN 2 to the Ground pin. Do not
connect both the REMOTE IN 1 and the REMOTE IN 2 to the Ground pin
simultaneously.
Route input 1 to the output, by
attaching PIN 1 to the Ground:
Route input 2 to the output, by
attaching PIN 2 to the Ground:
Figure 6: Remote Terminal Block Connector
When both XGA INPUT 1 and XGA INPUT 2 are connected, the signal from
XGA INPUT 1 routes to the output (factory default). However, you can force
the routing of XGA INPUT 2 to the output by attaching PIN 2 to the Ground.
Even if no input is present on XGA INPUT 1, you can force the routing of the
output from XGA INPUT 1 (displaying a blank screen) by attaching PIN 2 to
the Ground.
1 Note that the connection should be permanent, since the WP-211DS will revert to an automatic switcher when the
connection is removed
