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 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.

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/.

TP-141, TP-142 - 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, unbalanced 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 up to 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

(164ft) on standard CAT 5 cable. For longer distances, heavier gauge cable

should be used (TP cable is still suitable for the video/audio transmission, but not

for feeding the power at these distances). For units which are connected via RJ-45

TP-141, TP-142 - Overview

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 TP cable exceeding a distance of 50m, separate power supplies should be

connected to the transmitter and to the receiver simultaneously.

3.2 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.

3.3 Defining the TP-141 XGA/Audio Line Transmitter

The TP-141 is an XGA/stereo audio line transmitter that receives an XGA signal

and an unbalanced stereo analog audio signal, codes them, and transmits them

over CAT 5 cable to a TP-142 receiver. Figure 1 defines the TP-141.

3.4 Defining the TP-142 XGA/Audio Line Receiver

The TP-142 is an XGA/audio line receiver that receives the coded CAT 5 signal

transmitted by a TP-141, decodes it and converts it to XGA, stereo analog and

S/PDIF digital audio outputs. Figure 2 defines the TP-141.
