KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

3 Overview

The TP-141 and TP-142 are a high-immunity, extended-range twisted pair
transmitter and receiver for computer graphics video and unbalanced stereo
audio signals.

The TP-141 converts computer graphics video and audio inputs to twisted
pair signals, and the TP-142 converts the twisted pair signals back into
computer graphics video, unbala nced stereo and S/PDIF digital audio
signals. Together the TP-141 and TP-142 form a computer graphics
video/audio line transmitter/receiver system.

More specifically, the products feature:

• Highest immunity from any kind of interference

• Resolution exceeding UXGA

• HDTV compatibility

• Simultaneous unbalanced stereo and S/PDIF (24-bit 48kHz) audio

outputs (TP-142)

• Level (gain) and EQ (peaking) controls (TP-142)

• System range up to 250m (750ft)

• Power Connect™ System - Only one unit in a system, the transmitter or

the receiver, needs to be connected to a power source when the devices
are within 50m (150ft) of each other

Note: The TP-141 and TP-142 are not compatible with existing Kramer TP
units such as the TP-121, TP-122, and so on.

3.1 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 on standard CAT 5 cable. For longer distances, heavy gauge
cable should be used

1

. For units which 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 which 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 CAT 5 cable exceeding a distance of 50m, separate power suppli es
should be connected to the transmitter and to the receiver simultaneously.

1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

3

Overview

3.2 Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)

We recommend that you use Shielded Twisted Pair (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. For
cases where there is skewing, our UTP skew-free cable, Kramer BC-XTP,
may be used. Bear in mind, though, that we advise using STP cables where
possible, since the compliance to electromagnetic interference was tested
using those cables.

Although Unshielded Twisted Pair (UTP) cable might be preferred for long
range applications, the UTP cable should be installed far away from electric
cables, motors and so on, which are prone to cre ate electrical interference.
However, since the use of UTP cable might cause inconform ity to
electromagnetic standards, Kramer does not commit to meeting the standard
with UTP cable.

3.3 Recommendations for Achieving the Best Performance

hieve the best performance:

To ac

• Use only good quality connection cables

1

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 and position your Kramer
TP-141/TP-142 away from moisture, excessive sunlight and dust

5 Connecting the XGA/Audio Line Transmitter/Receiver

You can use the TP-141 and TP-142 to configure an XGA / Audio
Line-to-Twisted Pair Transmitter and Receiver system.

To connect the TP-141 XGA/Audio Line Transmitter with the TP-142
XGA/Audio Line Receiver, as illustrated in Figure 4

, do the following:

1. On the TP-141, connect the XGA source (for example, the graphics card of a

laptop) to the XGA INPUT 15-pin HD (F) connector.

2. Connect an audio sou rce to the AU DIO IN 3.5mm mini jack, for example,
using a Kramer C-GMA/GMA cable (VGA 15-pin HD (M ) +audio jack t o
VGA 15-pin HD (M) +audio jack)

2

.
Alternatively, you can connect an XGA source to the XGA INPUT 15-pin
HD (F) connector, and a separat e audio source to the A UDIO IN 3. 5mm mini
jack.

1 By default, both switches are set to the left (for a negative V SYNC and H SYNC polarity)

3. On the TP-142, connect the XGA OUT 15-pin HD (F) co nnector to the XGA

acceptor (for example, a display).

4. Connect the AUDIO OUT S/PDIF RCA connector to the digital audio
acceptor (for example, an AV receiver).

5. Connect the ANALOG 3.5mm mini jack to the analog audio acceptor (for
example, a stereo audio recorder).

6. Connect the LINE OUTPUT R J-45 connect or on the TP-141 to the LINE IN
RJ-45 connector on the TP-142, via CAT 5 (UT P or STP) cabling, (see
connector pinouts in section 5.1

).

7. Connect the 12V DC power adapter to the power socket of either the TP-141
or the TP-142 and connect the adapter to the mains electricity. The Power
