3 Overview
This user manual describes the following Kramer TOOLS:
TP-104/TP-104(HD) XGA Line Transmitter / DA, which is a line
transmitter / 1:4 DA that receives an XGA signal and transmits it over 4
CAT5 cables to appropriate receivers, see section 4
TP-105/TP-105(HD) CAT5 Line Driver / DA, which receives a CAT5
input

, and distributes it to 2 identical outputs, see section 5
TP-121 XGA / Audio Line Transmitter and the TP-122 XGA / Audio Line
Receiver, see section 6
TP-123 XGA / Audio / Data Line Transmitter and the TP-124 XGA /
Audio / Data Line Receiver, see section 7
This section describes:
The power connect feature, see section 3.1
Using shielded twisted pair (STP) / unshielded twisted pair (UTP), see
section 3.2
Recommendations for achieving the best performance, see section 3.3
3.1 About the Power Connect Feature
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter— to either the transmitter or the receiver.
The other unit is fed via the cable connecting between the transmitter/receiver.
The Power Connect feature applies as long as the cable can carry power. The
distance does not exceed 50 meters on standard CAT5 cable, for longer
distances, heavy gauge cable should be used
2
.
For a CAT5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
1 Video only
2 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

Overview
5
3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded twisted
pair (STP) cable is used. However, the shield itself does create a capacitance
that degrades the frequency response of the machines. For shorter distances, of
50m or so, shielded twisted pair (STP) cable is preferred because it provides
protection from interference (degradation is not apparent).
For long range applications, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away from
electric cables, motors and so on, which are prone to create electrical interference.
3.3 Recommendations for Achieving the Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
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 and position your
Kramer TOOLS away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

7.1 Your TP-123 XGA / Audio / Data Line Transmitter
The TP-123 is a high performance transmitter that accepts a computer
graphics input signal, an unbalanced stereo analog audio signal, unidirectional
(RxD) RS-232 control commands and 12V DC power, over CAT5 cable, and
transmits to a TP-124 receiver. The stereo analog audio signal is converted to
the digital audio (S/PDIF) stream before transmitting, thus preserving the
quality of the audio source signals.
The TP-123 / TP-124 pair has a transmission range of more than 300 ft.
(more than 100 meters) over UTP cabling. In addition, the TP-123:

7.2 Your TP-124 XGA / Audio / Data Line Receiver
The TP-124 is a high performance receiver obtaining the computer graphics
signal/audio/control data from the Kramer TP-123 via UTP cabling at its CAT5
Line input. The TP-124 outputs a computer graphics signal, an unbalanced
stereo analog audio signal, a converted digital audio (S/PDIF) signal and
RS-232 control commands. The unidirectional (TxD) RS-232 interface makes it
possible to control virtually any devices over a transmission range of more than
300 ft. (more than 100 meters) over UTP cabling. The TP-124 can power or be
powered by the TP-123 transmitter over the same CAT5 cable.
In addition, the TP-124 features:
Level and EQ. control for the XGA signals
The capability to change the polarity of decoding H and V Sync
24 bit 48kHz S/PDIF digital audio that supplies the highest quality audio

8 Connecting the XGA / Audio Line Transmitter / Receiver
You can use the TP-121 and TP-122 to configure an XGA/Audio Line-to-Twisted
Pair Transmitter and Receiver system.
To connect the TP-121 XGA / Audio Line Transmitter with the TP-122 XGA /
Audio Line Receiver, as the example in Figure 12 illustrates, do the following:
1. On the TP-121, connect the XGA source (for example, a laptop’s graphics
card) to the XGA INPUT HD15F connector and an audio source to the
AUDIO IN 3.5mm mini jack, for example, using a Kramer C-GMA/GMA
cable (VGA HD15M +Audio jack to VGA HD15M +Audio jack)

.
Alternatively, you can connect an XGA source to the XGA INPUT HD15F
connector, and a separate audio source to the AUDIO IN 3.5mm mini jack.
2. On the TP-122, connect the XGA OUT HD15F connector to the XGA
acceptor (for example, a display), and connect the AUDIO OUT S/PDIF RCA
connector to the digital audio acceptor (for example, an AV Receiver), and the
ANALOG 3.5mm mini jack to the analog audio acceptor (for example, a
stereo audio recorder).
3. Connect the LINE OUTPUT RJ-45 connector on the TP-121 to the LINE IN
RJ-45 connector on the TP-122, via UTP cabling (with a range of more than
300ft (>100m)), see section 8.1.
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity on both
2
the TP-121 and the TP-122.
The signal from the XGA source is transmitted via CAT5 cable, decoded and
converted at the XGA OUT HD15F connector to the XGA acceptor.
5. On the TP-122:
