2 TP-121/3/5EDID, PT-110EDID - 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
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).
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)
•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 products 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
Caution: There are 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
2.3 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/.

4 TP-121/3/5EDID, PT-110EDID - Overview
3 Overview
This user manual describes the following devices:
•TP-121EDID XGA/Audio Line Transmitter (see Section 4)
•TP-123EDID XGA/Audio/Data Line Transmitter (see Section 5)
•TP-125EDID XGA/Audio/Data Line Transmitter (see Section 6)
•PT-110EDID XGA Line Transmitter (see Section 7)
This section also describes:
•Using shielded twisted pair (STP)/unshielded twisted pair (UTP), see
Section 3.1
•The power connect feature, see Section 3.2
3.1 About Shielded Twisted Pair (STP)/Unshielded Twisted
Pair (UTP)
We recommend that you use Shielded Twisted Pair (STP) cable, and stress that
the compliance to electromagnetic interference was tested using STP cable. There
are different levels of STP cable available, and we advise you to use the best
quality STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP
is intended for analog signals where skewing is not an issue.
In cases where there is skewing, our Unshielded Twisted Pair (UTP) skew-free
cable, Kramer BC-XTP, may be advantageous, and UTP cable might also be
preferable for long-range applications. In any event when using UTP cable, it is
advisable to ensure that the cable is installed far away from electric cables, motors
and so on, which are prone to create electrical interference.

3.2 About the Power Connect™ Feature
The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m
(164ft) on standard CAT 5 cable. For longer distances, heavy-gauge cable should
be used (TP cable is still suitable for the video/audio transmission, but not for
feeding power at these distances). For units that are connected via RJ-45
connectors, make sure that the shield of the STP cable is connected to the metal
casing of the connectors on both ends of the cable. For units that are connected
via terminal block connectors, the shield of the STP cable must be connected to a
ground terminal on the units at both ends. (Use the ground terminal of the power
supply connection if necessary.) For a TP cable exceeding a distance of 50m,
separate power supplies should be connected to the transmitter and to the
receiver simultaneously.

This section describes the TP-121EDID XGA/Audio Line Receiver.
4.1 Overview
The TP-121EDID is a high-performance XGA/stereo audio line transmitter. It
inputs an XGA signal (up to WUXGA, 1080p) and an unbalanced stereo audio
signal and transmits them over CAT 5 cable to a receiver (for example, the Kramer
TP-122N). It converts the unbalanced stereo audio signal to a digital audio
(S/PDIF) stream before transmitting, to preserve the quality of the audio signal.
When the TP-121EDID is connected to a display device and the EDID CAPTURE
button is pressed, the TP-121EDID reads and stores the EDID (Extended Display
Identification Data) from the display device. The display can be disconnected and
later reconnected without rebooting the operating system.
The TP-121EDID features:
•A maximum resolution of WUXGA and 1080p
•A transmission range of more than 300ft (100m), and a 20kHz audio
bandwidth with an S/N ratio that exceeds 80dB on the same
transmission range
•EDID Capture that copies and stores the EDID from a display device
•The Power Connect Feature that transmits power to the receiving
device, or receives power from it, over twisted pair cable
•12V DC power

4.2 Connecting the TP-121EDID XGA/Audio Line
Transmitter
You can use the TP-121EDID together with the TP-122N to configure a twisted
pair transmitter and receiver system, to transmit the video and audio signals via
CAT 5 cable.
Before connecting the transmitter and receiver system you can
acquire the EDID from the display or set the system to the default
EDID, see Section 9.
