Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
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/WP-20 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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 neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer WP-20 away from moisture, excessive sunlight and dust.

Overview
Congratulations on purchasing your Kramer WP-20 Wall Plate. WP-20 is a high-performance,
4K, multi-format, wall-plate switcher and transmitter over extended-reach HDBaseT. Offering
intelligent Maestro automation, with priority and last-connected switching options, it
automatically switches and operates room according to the selected switching scheme based
on active video signal detection.
All references in this manual to the WP-20 in this manual also apply to the WP-20E European
versions.
The WP-20 features:
•Simple and Powerful Maestro Room Automation –Intuitive user interface enables you to
fully automate your meeting room elements. Configure lights, shades, devices and more
to be activated by an extensive range of triggers, including input/output connectivity,
routing, and button pressing. By minimizing user intervention, Maestro room automation
saves meeting prep time and minimizes human error before presentations.

saves meeting prep time and minimizes human error before presentations.
•High Performance Switcher Transmitter –Professional HDBaseT Switcher transmitter
for providing extended-reach signals over twisted pair copper infrastructures. This
switcher transmitter is a standard transmitter that can be connected to any market-
available HDBaseT-compliant extension product.
•BYOD Plug & Play Auto Switcher –Automatically plays the switched user device source
signal on the connected display according to user-configured preferences, such as
priority or last-connected input. When the user manually switches, by pressing a button,
the auto switching is overridden.
•Simple Switching Operation –Local buttons or remotely connected contact-closure
buttons for flexible user input selection and switching control.
•HDMI™Signal Switching –HDCP compliant, supporting deep color, x.v.Color™, lip
sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS-HD, 2K, 4K, and 3D as
specified in HDMI 2.0.
•I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent EDID handling,
processing, locking and pass-through algorithm ensures plug & play operation for HDMI
source and display systems.
•Multi-channel Audio Switching –Up to 32 channels of digital stereo uncompressed
signals for supporting studio-grade surround sound.
•Audio Embedding –An auto-detected analog stereo audio input, per user selection, is
converted into a digital signal and embedded in the output HDMI signal, replacing the
source HDMI audio input signal. This enables, for example, a presenter to temporarily
override the playing source audio with speech description.
•Audio De-embedding –The digital audio signal passing-through to the output, is de-
embedded, converted to an analog signal and sent to the stereo analog audio output.
This enables playing the audio on locally connected speakers, in parallel to playing it on
the speakers connected to the AV acceptor device (such as TVs with speakers).
•Ethernet Extension –Ethernet interface data flows in both directions, allowing extension
of up to 100Mbps Ethernet connectivity for LAN communication and device control.
•Bidirectional RS-232 Extension –Serial interface data flows in both directions, allowing
data transmission and device control.
•Reliable PoE (Power over Ethernet) Powering –Auto-senses the extension line PoE
status, it accepts power from a remote PoE provider such as a PoE matrix, with optional
mains powering from connected power adapter.
•Cost-effective Maintenance –Status LED indicators for HDMI, VGA and HDBT ports
facilitate easy local maintenance and troubleshooting. Remote IP-driven device
management via built-in web pages and RS-232 connection. Local and remote firmware
upgrade via RS-232 or Ethernet connection tool ensure lasting, field-proven deployment.
•Easy Installation –Compactly fits into standard US, EU and UK 2-gang in-wall box size,
supporting decorative integration with room deployed user interfaces such as electrical
switches. Wall-plate installation is fast and cost-effective via a single twisted pair cable,
providing both video signal and power (PoE) connections.

Connecting WP-20 Wall Plate
Always switch off the power to each device before connecting it to your WP-20. After
connecting your WP-20, connect its power and then switch on the power to each device.
Figure 5: Connecting the WP-20 Wall Plate
When the receiver in use does not support Ethernet, you can replace the left-hand side
faceplate with an optional part that does not have a cutout for the RJ-45 Ethernet connector.
To connect the WP-20, as illustrated in the example in Figure 5:
1. Connect an HDMI source, (for example, a Blu-ray disk player) to the HDMI input.
2. Connect a PC graphics source, (for example, a laptop) to the PC In input.
3. Connect an unbalanced stereo audio source, (for example, the audio output from the
laptop) to the AUDIO IN 3.5mm mini jack.
4. Connect the Ethernet RJ-45 connector on the front panel to the LAN.
5. Connect the HDBT OUT RJ-45 connector on the rear panel of the WP-20 to an HDBT-
compatible receiver (for example, the TP-780Rxr).
6. Connect the AUDIO OUT 3-pin terminal block on the rear panel of the WP-20 to the
unbalanced, stereo audio acceptor, (for example, a power amplifier with speakers).
7. Connect the REMOTE, 5-way terminal block to momentary, contact-closure switches,
8. If the device is not connected to a PoE provider, connect the power adapter to the
WP-20 and to the mains power, (not shown in Figure 5).
