You must use Shielded Twisted Pair (STP) cabling with the
PT-571HDCP and PT-572HDCP+.
Use only a straight pin-to-pin cable with RJ-45 connectors that
meet the EIA /TIA 568B standard. Failure to do so may result in
damage to the device(s).

2 PT-571HDCP/PT-572HDCP+ - 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
•Use Kramer high performance high resolution cables
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer PT-571HDCP and PT-572HDCP+ transmitter/receiver
pair away from moisture, excessive sunlight and dust
Caution: No operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning: Disconnect the power and unplug the unit from the
wall before installing
Go to http://www.kramerelectronics.com to check for up-to-date user
manuals, application programs, and to check if firmware upgrades
are available (where appropriate).

PT-571HDCP/PT-572HDCP+ - Overview 3

3 Overview
The PT-571HDCP is a DGKat™ twisted pair transmitter for DVI signals. The
PT-571HDCP converts a DVI signal to a single twisted pair signal and the
PT-572HDCP+ converts the twisted pair signal back to a DVI signal.
The DVI Line Transmitter/Receiver system features:
•Maximum data rate/bandwidth up to 1.65Gbps, WUXGA, 1920x1080p
•HDTV compatibility and HDCP compliance
•EDID PassThru that passes EDID signals between the source and display
•3D pass-through
•System Range – Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on
shielded BC-DGKat524 cable; 90m (295ft) at 1080i, or up to 70m (230ft) at
1080p on shielded BC-DGKat623 cable; 100m (330ft) at 1080i or up to 90m
(295ft) at 1080p on shielded BC-DGKat7a23 cable
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 7a cables may
not reach these ranges
•DGKat™ Signal Integration – Kramer’s unique technology for converting
TMDS as well as control and communication to signals that run over twisted
pair cables
•Power Connect™ that feeds 12V DC over the CAT 5 cable from transmitter
to receiver (see Section 3.2)
•Ultra-Compact Pico TOOLS™ – 4 units can be rack mounted side −by−side
in a 1U rack space with the optional RK−4PT rack adapter.
Use only shielded cable where both ends of the shield are soldered
to ground to eliminate ESD interface.

4 PT-571HDCP/PT-572HDCP+ - Overview
3.1 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5/CAT 6/CAT 7a cables.
3.2 About the Power Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, needs to be connected to a power source when the
devices are within 90m (270ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
90m on standard CAT 5 cable. For longer distances, heavy gauge cable should be
used (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances).
3.3 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel, protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.

Transmitter
The Kramer Pico TOOLS PT-571HDCP DVI Line Transmitter receives a DVI
signal, encodes it, and transmits it over a CAT 5 cable to the PT-572HDCP+. The
PT-571HDCP has:
•A DVI input connector
•An RJ-45 CAT 5 output connector
•One power status LED

signal over a CAT 5 cable transmitted from the PT-571HDCP, decodes it, and
converts it to a DVI output.
The PT-572HDCP+ has:
•A DVI output connector
•An RJ-45 CAT 5 input connector
•One power status LED

6 Connecting the PT-571HDCP and
PT-572HDCP+ Transmitter Receiver Pair
Always switch off the power to each device before connecting it to your
Transmitter and Receiver pair. After connecting your Transmitter and
Receiver pair, connect the power and then switch on the power to
each device.
You can use the PT-571HDCP DVI Line Transmitter with the PT-572HDCP+ DVI
Line Receiver to configure a DVI transmitter/receiver system.
To connect the PT-571HDCP to the PT-572HDCP+, as illustrated in the example
in Figure 3, do the following:
1. Connect the CAT 5 OUT RJ-45 connector on the PT-571HDCP to the CAT 5
IN RJ-45 connector on the PT-572HDCP+ via a CAT 5 cable (see Section
6.1).
2. On the PT-571HDCP, connect a DVI source (for example, a computer
graphics source) to the DVI IN connector.
3. On the PT-572HDCP+, connect the DVI OUT connector to a DVI acceptor
(for example, a display).
4. Connect the 12V DC power adapter to the power socket on the
PT-571HDCP and/or the PT-572HDCP+ and connect the adapter to the
mains electricity (not shown in Figure 3).
