Overview

3.1 About the WP-230
The Kramer WP-230 XGA/Video/Audio Line Driver wall plate includes:
A computer graphics XGA INPUT on a standard HD-15 connector
An amplified and equalized RGBHV output on 5 BNC connectors
A composite video input on an RCA connector with a corresponding
composite video output on a 2-pole terminal block
An s-Video input on a 4p connector with a corresponding s-Video output
on a 4-pole terminal block
An unbalanced stereo PC AUDIO INPUT on a 3.5mm mini jack with a
corresponding balanced stereo PC AUDIO OUT on a 5-pole terminal block
An unbalanced stereo LINE AUDIO INPUT on two RCA connectors with
a corresponding balanced stereo LINE AUDIO OUT on a 5-pole terminal block
In particular, the WP-230 has:
Trimmer controls for XGA EQ.1, and CV Level / EQ.1
Separate trimmer controls for right and left line audio level, and C and Y
levels
Resolution exceeding UXGA, that ensures transparent operation
A standard 12 Volt DC feed
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 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.
Some Kramer twisted pair products include the Power Connect feature2. The
WP-230 does not have this feature.
1 Cable equalization
2 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 over the same cable. The Power Connect feature applies as long as the cable
is heavy gauge cable (that is, it can carry power). The distance does not exceed 50 meters on standard CAT5 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 cable

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
Positioning your WP-230 away from moisture, excessive sunlight and dust

5.1 Installing the WP-230
To install your WP-230:
1. Connect the 5 RGBHV BNC output connectors1 to the pre-installed
wiring in the wall box opening that connects to the XGA acceptor (for
example, a projector), as Figure 5 defines.
Figure 5: WP-230 RGBHV Outputs
2. Connect the LINE AUDIO OUT and / or the PC AUDIO OUT terminal
blocks, as one of the following:
Figure 6: Connecting the LINE AUDIO OUT / PC AUDIO OUT
3. Connect the wires of the coax cable to the CV OUT pins2, taking care that
polarity is correct.
4. Connect the wires of the coax cable to the Y/C OUT pins3, taking care
that polarity is correct.
5. Connect your 12V DC power supply to the POWER pins4, taking care that
polarity is correct.
6. Insert the WP-230 directly into the wall box opening, and then mount the
front panel securely using the screws.
1 The WP-230 could be used for component HDTV by connecting YPbPr in place of GBR, and not connecting H and V
2 Connect the composite video wire to the CV OUT pin and the Ground wire to the GND pin (see Figure 8)
3 Connect the luminance signal “Y” wire to the Y pin and the Ground wire to its corresponding GND pin, and connect the
chrominance signal “C” wire to the C pin and the Ground wire to its corresponding GND pin (see Figure 8)
4 Connect the wire labeled “+” to the +12V pin, and the wire labeled “–” to the GND pin

5.3 Operating the WP-230
To operate your WP-230:
1. Connect your computer graphic’s source (for example, a laptop’s digital
graphics card) to the XGA INPUT HD15F connector and to the PC
AUDIO INPUT 3.5mm mini jack, for example, using a Kramer
C-GMA/GMA cable (VGA HD15M +Audio jack to VGA HD15M
+Audio jack)1.
(Alternatively, you can connect separate audio source to the PC AUDIO
INPUT.)
2. Connect the composite video source (for example, a composite video
player) to the CV IN RCA connector and to the LEFT and RIGHT LINE
AUDIO INPUT RCA connectors.
3. Connect the s-Video source (for example, an s-Video player) to the
s-Video IN 4p connector. Instead of connecting the audio from the
composite video player, you can as an alternative connect the audio from
the s-Video player to the LEFT and RIGHT LINE AUDIO INPUT RCA
connectors.
4. Connect2 the CAT5 RJ-45 connector (see section 5.2).
5. If required, adjust3 the left and/or right LINE AUDIO levels, and/or the Y
and/or C levels, and/or the XGA EQ.4 level, and/or the CV level / EQ.
