Congratulations on purchasing your Kramer WP-20 Wall Plate. This product, which
incorporates HDMI™ technology, is ideal for:
•Display systems requiring simple, automatic input selection
•Multimedia and presentation source selection
•Video distribution in hotel rooms and schools
Note: All references in this manual to the WP-20 in this manual also apply to the
WP-20E European versions.

2 WP-20 - Getting Started
2 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).
2.1 Achieving the Best Performance
To achieve the 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 neighbouring electrical appliances that may adversely
influence signal quality
•Position your WP-20 away from moisture, excessive sunlight and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
2.2 Safety Instructions DC
Caution:
There are no operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics power supply that is
provided with the unit
Warning: Disconnect the power and unplug the unit from the wall
before installing

2.3 Shielded Twisted Pair/Unshielded Twisted Pair
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-HDKat6a (CAT 6 23 AWG) HDBaseT
certified, and the Kramer BC-DGKat7a23 (CAT 7a 23 AWG) cables. These
specially built cables significantly outperform regular CAT 6 and CAT 7a cables.
2.4 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims
to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country go
to our recycling pages at http://www.kramerav.com/support/recycling/.

4 WP-20 - Overview
3 Overview
WP−20 is a 4K UHD, HDBaseT active wall plate auto switcher for HDMI, VGA and
analog audio signals that supports resolutions up to 4K@60Hz (4:2:0) UHD. The
device has EDID management, various control options and audio embedding. The
unit is a fully−featured auto−switcher with the installation convenience and
operational simplicity of a wall plate. WP−20 is easy to configure, can be powered
remotely over Ethernet (PoE) and is designed for any size room.
WP-20 accepts an HDMI and PC graphics video input, an Ethernet signal, serial
data, and an unbalanced stereo audio input (which is embedded into the output
signal), and transmits the signal via HDBaseT (Twisted Pair) cable to a compatible
receiver (for example, the TP-780Rxr). WP-20 is a PoE (Power over Ethernet)
receiver and can be powered by a compatible PoE provider, (for example, PSE-1).
WP-20 supports a range of up to 130m (430ft) at normal mode (2K), up to 100m
(330ft) at normal mode (4K @60Hz (4:2:0)); up to 180m (590ft) extended mode
(1080p @60Hz @24bpp) when using BC-UNIKAT cables.
For optimum range and performance, use the recommended Kramer
cables available at www.kramerav.com/product/WP-20. Note that the
transmission range depends on the signal resolution, graphics card and
display used. The distance using non-Kramer CAT 5, CAT 6, and CAT 7
cables may not reach these ranges.
In particular WP-20 features:
•Support for 4K UHD, (data rate of up to 10.2Gbps)
•Automatic input selection based on priority selection or last connected input
•Manual input selection
•Automatic live input detection based on video clock presence
•Automatic analog audio detection and embedding

WP-20 – Overview 5
•Power over Ethernet (PoE) which passes electrical power along with data over
Ethernet cabling. This allows a single cable to provide both data connection
and electrical power to compatible devices
•Control via Kramer Protocol 3000 and embedded Web pages over a LAN
•HDTV support
•HDMI with Deep Color, x.v.Color™ and 3D
•HDCP compliancy—works with sources that support HDCP repeater mode
•I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent EDID handling
& processing algorithm ensures Plug and Play operation for HDMI systems
•A lockable EDID
•Remote control via contact-closure switches
•Equalization and re-clocking of the data
•Support for digital audio formats
•Availability in US and European versions
3.1 About HDBaseT™ Technology
HDBaseT™ is an advanced, all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV – and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed, full high-definition video, audio, IR, as well as various
control signals.
The products described in this user manual are HDBaseT certified.

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 6: Connecting the WP-20 Wall Plate
Note: When the receiver in use does not support Ethernet, you can replace the left
hand side faceplate with an optional part (WP-20-BLNK(W) P/N 68-80305099 or
WP-20-BLNK(B) P/N 68-80305199) that does not have a cutout for the RJ-45
Ethernet connector.
To connect the WP-20, as illustrated in the example in Figure 6:
