2 TP-125xl/TP-126xl - 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 TP-125xl and TP-126xl 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 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend the use of Kramer’s BC-SXTP skew-free, shielded Twisted Pair
(STP) cable. If unshielded twisted pair (UTP) cable is preferred, use Kramer’s
BC-UXTP skew-free, UTP cable.
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/.

4 TP-125xl/TP-126xl - Overview
3 Overview
The TP-125xl and TP-126xl are a high-performance, TP (Twisted Pair) transmitter
and receiver pair for transmitting computer graphics video, unbalanced stereo
audio, and bidirectional RS-232 data signals over extended distances using CAT
5/6 cable.
The TP-125xl encodes computer graphics video, unbalanced stereo audio and
RS-232 data into a TP signal. The TP-126xl decodes the TP signal into computer
graphics video, digital unbalanced stereo audio, and RS-232 data signals. The
TP-125xl and TP-126xl together form an extended computer graphics/audio/data
line transmission and reception system.
More specifically, the TP-125xl and TP-126xl support:
•Video resolutions up to UXGA (1920 x 1200)
•EDID (TP-125xl)
•HDTV
•Level (gain) and equalization (peaking) adjustment (TP-126xl)
•Full duplex, bidirectional RS-232 transmission
•Increased level of protection against noise, spikes and interference in
adverse environments
•Transmission range of up to 250m (820ft)

4 Defining the TP-125xl/TP-126xl Line
Transmitter and Receiver
This section defines the:
•TP-125xl UXGA/Audio/Data Line Transmitter (see Section
4.1)
•TP-126xl UXGA/Audio/Data Line Receiver (see Section 4.2)
The TP-125xl has inputs for:
•Computer graphics video
•Unbalanced stereo audio
•RS-232 data
The TP-125xl encodes the video, audio and data signals and transmits them over
STP cable to a TP-126xl receiver. RS-232 data and commands flow
bidirectionally, allowing status requests and control of a destination unit. The
RS-232 interface makes it possible to control almost any device over a
transmission range of up to 250m over STP cabling.
The TP-126xl accepts the encoded signal over STP from the TP-125xl and
outputs computer graphics video, unbalanced stereo audio, digital audio and
RS-232 data.

RS-232 interface) to the RS-232 3-pin terminal block
An unbalanced, stereo audio source, (for example, the audio output
from a laptop) to the Audio In 3.5mm mini jack
2. On the TP-126xl, connect:
The UXGA Out 15-pin HD (F) connector to the video acceptor, (for
example, an AV display system)
The RS-232 3-pin terminal block to the controlled device, (for example,
an AV display system)
The Audio Out Analog 3.5mm mini jack to the unbalanced, stereo
audio acceptor, (for example, an AV display system with speakers)
The Audio Out S/PDIF RCA connector to the digital audio acceptor,
(for example, a DAT recorder)
3. Using STP cabling, connect the TP-125xl Line Out RJ-45 connector to the
TP-126xl Line In RJ-45 connector (see Section 2.3).
4. Connect the power adapters to the power sockets on the TP-125xland
TP-126xl, and connect the adapters to the mains electricity (not shown in
Figure 5).
5. If necessary, adjust the level and equalization for an optimum picture (see
Section 6.2).

6 Operating the TP-125xl and TP-126xl
6.1 Capturing the EDID
The TP-125xl is programmed with a default EDID. To replace the default EDID
you can replace it with the EDID from a display device.
To capture a new EDID:
•With the display device connected to the TP-125xl, press the EDID Capture
button on the front panel of the TP-125xl.
If the EDID is successfully captured the Status LED flashes slowly for a few
seconds and then lights solid. If the EDID is not successfully captured the
Status LED flashes quickly for a few seconds then lights solid when the
default EDID is loaded.
6.2 Adjusting the Level and Equalization on the TP-126xl
You can manually adjust the signal level and equalization using the trimmers on
the front of the TP-126xl to achieve an optimum picture.
To adjust the level and equalization on the TP-126xl:
1. Use a small screwdriver to slowly turn the Level trimmer clockwise to
increase or anticlockwise to reduce the signal level of the TP-126xl.
2. Use a small screwdriver to slowly turn the EQ trimmer clockwise or
anticlockwise until you achieve an optimum picture.
