2 TP-122N - 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)

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer TP-122N away from moisture, excessive sunlight and

dust

Caution: 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

TP-122N - Overview 3

3 Overview

The Kramer TP-122N is an XGA/audio line receiver that receives the coded CAT 5

signal transmitted by a TP-121EDID XGA / Audio Line Transmitter, for example,

decodes it and converts it to XGA, stereo analog and S/PDIF digital audio outputs.

The TP-122N, with the TP-121EDID transmitter, allows an operation range of more

than 300ft (more than 100m) over standard CAT 5 cable.

The TP-122N:

•Is HDTV Compatible

•Has a maximum resolution of WUXGA and 1080p

•Includes EQ. and level controls

•Can power or be powered by the transmitter over the same CAT 5 cable

when the devices are within 50m (150ft) of each other

•Is 12V DC fed

The TP-122N is housed in compact TOOLS®enclosure where three units can be

rack mounted side-by-side in a 1U rack space with the optional RK-3T rack

adapter.

3.1 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.

4 TP-122N - Overview

3.2 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

(CAT 5 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 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 supplies should

be connected to the transmitter and to the receiver simultaneously.

4 Connecting the TP-122N XGA/Audio Line

Receiver

You can use the TP-121EDID and TP-122N to configure an XGA/Audio Line-

to-Twisted Pair Transmitter and Receiver system.

To connect the TP-121EDID XGA/Audio Line Transmitter with the TP-122N

XGA/Audio Line Receiver, as the example in Figure 2 illustrates, do the following:

1. On the TP-121EDID, connect the XGA source (for example, a laptop’s

graphics card) to the XGA INPUT 15-pin HD (F) connector and an audio

source to the AUDIO IN 3.5mm mini jack, for example, using a Kramer

C-GMA/GMA cable (VGA 15-pin HD (M) +Audio jack to VGA 15-pin HD (M)

+Audio jack).

2. On the TP-122N, connect the XGA OUT 15-pin HD (F) 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-121EDID to the

LINE IN RJ-45 connector on the TP-122N, via UTP cabling (with a range of

more than 300ft (>100m)), see Section 4.1.

4. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity on both the TP-121EDID and the TP-122N.

The signal from the XGA source is transmitted via CAT 5 cable, decoded

and converted at the XGA OUT 15-pin HD (F) connector to the XGA

acceptor.

If you cannot connect the power to both the TP-121EDID and TP-122N, you can just

connect the power to the TP-122N

5. On the TP-122N adjust the video output signal level and/or cable

compensation equalization level, if required.

Use a screwdriver to carefully rotate the trimmer, adjusting the appropriate level
