TP-121xl/TP-122xl - 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
Go to http://www.kramerelectronics.com/support/product_downloads.asp
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 (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 neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer TP-121xl and TP-122xl 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 power cord that is supplied with the unit
Warning:
Do not open the unit. High voltages can cause
electrical shock! Servicing by qualified personnel only
Warning:
Disconnect the power and unplug the unit from the wall
before installing

2.3 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 60m (197ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
60m on standard TP cable. (Heavier gauge cable may be used to extend the
Power Connect™range.)
2.4 Shielded Twisted Pair/Unshielded Twisted Pair
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.
2.5 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/.

TP-121xl/TP-122xl - Overview
3 Overview
The TP-121xl and TP-122xl is a high-performance, TP (Twisted Pair) transmitter
and receiver pair for transmitting computer graphics video and unbalanced stereo
audio signals over extended distances using CAT 5/6 cable.
The TP-121xl and TP-122xl together form an extended computer graphics/audio
line transmission and reception system.
The TP-121xl encodes computer graphics video and unbalanced stereo audio into
a TP signal. The TP-122xl decodes the TP signal into computer graphics video
and digital unbalanced stereo audio signals.
More specifically, the TP-121xl and TP-122xl support:
Video resolutions up to UXGA (1920 x 1200)
EDID (TP-121xl)
HDTV
Level (gain) and equalization (peaking) adjustment (TP-122xl)
Increased level of protection against noise, spikes and interference in
adverse environments
Transmission range of up to 250m (820ft)
Power Connect™ (see Section 2.3)

TP-122xl Receiver
This section defines the:
TP-121xl (see Section 4.1)
TP-122xl (see Section 4.2)
The TP-121xl has inputs for:
Computer graphics video
Unbalanced stereo audio
The TP-121xl encodes the video and audio signals and transmits them over STP
cable to a TP-122xl receiver.
The TP-122xl accepts the encoded signal over STP from the TP-121xl and
outputs computer graphics video, unbalanced stereo audio and digital audio.

Switch off the power to all devices before connecting them to your
TP-121xl/TP-122xl. After connecting your TP-121xl/TP-122xl, connect
the power to the transmitter and receiver and then switch on the power
to the other devices.
Figure 5: Connecting the TP-121xl Transmitter and TP-122xl Receiver
To connect the TP-121xl and the TP-122xl as illustrated in Figure 5:
1. On the TP-121xl, connect:
The computer graphics video source, (for example, the graphics output
from a laptop) to the UXGA In 15-pin HD connector (F)

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-122xl, connect:
The UXGA Out 15-pin HD (F) connector to the video acceptor, (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-121xl Line Out RJ-45 connector to the
TP-122xl Line In RJ-45 connector (see Section 2.2).
4. Because the devices support Power Connect, if they are within 60m of one
another, connect one of the power adapters to the power socket on either
the TP-121xl or the TP-122xl. If the devices are more than 60m apart
connect both power adapters to the devices and to the mains electricity (see
Section 2.2).
5. If necessary, adjust the level and equalization for an optimum picture (see
Section 6.2).

6 Operating the TP-121xl and TP-122xl
6.1 Capturing the EDID
The TP-121xl is programmed with a default EDID. The default EDID can be
replaced with the EDID from a display device.
To capture a new EDID:
With the display device connected to the TP-121xl, press the EDID Capture
button on the front panel.
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-122xl
To achieve optimum picture quality, you can manually adjust the signal level and
equalization using the trimmers on the front of the TP-122xl.
To adjust the level and equalization on the TP-122xl:
1. Use a small screwdriver to slowly turn the Level trimmer clockwise to
increase or anticlockwise to reduce the signal level of the TP-122xl.
2. Use a small screwdriver to slowly turn the EQ trimmer clockwise or
anticlockwise until you achieve an optimum picture.
