Congratulations on purchasing your Kramer PT-571HDCP and PT-572HDCP+

transmitter/receiver pair, which is ideal for the following typical applications:

•Boardrooms, conference rooms and training rooms

•Presentation systems

•Signal distribution and home theater

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

2 DVI IN Connector Connect to the DVI source

3 OUT RJ-45 Connector Connect to the IN RJ-45 connector on the PT-572HDCP+

4 ON LED Lights only when the machine is powered (whether directly

from the power adapter or via the PT-572HDCP+) and an

input is connected

If no input is connected the unit invokes the power save

mode automatically turning off the power

5 Defining the PT-572HDCP+ DVI Line

Receiver

The Kramer Pico TOOLS PT-572HDCP+ DVI Line Receiver receives an encoded

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

PT-572HDCP+ Transmitter Receiver Pair 7

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).
