manuals, application programs, and to check if firmware upgrades are
available (where appropriate).
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
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 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
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

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.kramerelectronics.com/support/recycling/.

WP-20 - Overview
For optimum range and performance, use Kramer's BC−HDKat6a and
BC−DGKat7a23 shielded twisted pair (STP) cables. 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.
3 Overview
The 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-588D or the TP-580RXR). The
WP-20 is a PoE (Power over Ethernet) receiver and can be powered by a
compatible PoE provider, (for example, the PSE-1).
The WP-20 supports a range of up to 130m (430ft) at normal mode (2K), up to
100m at normal mode (4K UHD); up to 180m (590ft) ultra mode (1080p @60Hz
@24bpp) when using BC−HDKat6a cables.
In particular the 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
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

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.

WP-20 - Principles of Operation
6 Principles of Operation
The WP-20 selects video and audio inputs based on the rules described below.
6.1 Input Selection
The video mode selection is set by the DIP-switches (see Section 8.1) to either
of the following modes:
Manual
Auto—Last connected or priority mode
In manual mode you select an input using either the remote input selection
switches, the Web-page interface, or P3000 commands, and switching occurs
whether or not there is a live signal present on the input.
In auto mode, the switching selection is performed based on either last
connected or priority input.
In last connected mode the WP-20 selects the input based on which input was
connected last. If the signal on this input is subsequently lost for any reason, the
input with a live signal and which was also the last connected is selected
automatically.
In priority mode, when the input sync signal is lost for any reason, the input with
a live signal and next in priority is selected automatically. This priority is
configurable; the default setting is HDMI > PC.
Note: In both last connected and priority modes, manually selecting an input
using the remote input selection switches overrides the last-connected automatic
selection.

6.2 Signal Loss and Unplugged Cable Timeouts
In both last connected and priority modes, when the input signal sync is lost (but
the cable is not removed) there is a default delay (ten seconds for video, not
applicable to the PC input, and five seconds for analog audio) before another
input is automatically selected. When an input cable is removed, there is a delay
before automatic switching takes place.
Both timeouts are configurable, (see Section 8.1).
Note: Analog audio is not output when there is no display connected. If a display
is connected, analog audio is output even in the absence of a video signal.
6.3 Audio Signal Control
The Option DIP-switches 3 and 4 (see Section 8.1) control the manner in which
audio is handled.
The following table describes which audio signal is embedded in the output.
When there is an audio signal but no video signal, the output is a black video
screen in conjunction with the analog audio signal.
Note: The default timeout for audio switching when the input signal is lost is five
seconds. This can be changed using either P3000 commands or the Web
pages.
14
WP-20 - Principles of Operation
6.4 VGA Phase Shift
To minimize phase on the input VGA signal, the VGA sampling phase can be
shifted using a remote, contact-closure switch connected to pins 1 and G of the
Remote terminal block. Each long press steps the phase shift up one step
starting from 0 and going to 31. When the phase shift is set to 31, another long
press steps the shift to 0.

7 Operating the WP-20
Powering up the WP-20 recalls the last settings from the non-volatile memory,
(that is, the configuration of the device when it was powered down).
7.1 Selecting an Input Manually
Any of the following methods can be used to select an input:
Protocol 3000 command, (see Section 13.2)
Remote contact-closure switch, (see Section 5.1)
Web pages, (see Section 9)
7.2 Locking the EDID
To prevent the stored EDID (either default or read from a device) from being
overwritten, you can lock the current EDID by either sending a Protocol 3000
command or by using the Web pages.
Note: Do not power up the display before locking the EDID.
7.3 Resetting the WP-20
To perform a soft reset of the WP-20:
Briefly press the Reset button.
To reset the WP-20 to factory default parameters:
Press and hold the Reset button for five seconds.
The device resets
The device is reset to factory default parameters

The analog audio output volume can be controlled using remote, contact-closure
switches connected to pins 3 and 4 of the Remote terminal block, (see
Section 5.1). For volume control using the Web pages, see Section 9.1 and for
using P3000 commands to control the volume see Section 13.2.
The up/down volume steps per press are detailed in the table below.
