Overview

3 Overview

This user manual describes the following:

•TP-121EDID XGA / Audio Line Transmitter (see section 4)

•TP-123EDID XGA / Audio / Data Line Transmitter (see section 5)

•TP-125EDID XGA / Audio / Data Line Transmitter (see section 6)

•PT-110EDID XGA Line Transmitter (see section 7)

This section describes:

•Using shielded twisted pair (STP) / unshielded twisted pair (UTP), see

section 3.1

•The power connect feature, see section 3.2

•Defining EDID, see section 3.3

•Recommendations for achieving the best performance, see section 3.4

3.1 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 create electrical interference.

However, since the use of UTP cable might cause inconformity to electromagnetic

standards, Kramer does not commit to meeting the standard with UTP cable.

3.2 About the Power Connect Feature

The Power Connect feature applies as long as the cable can carry power. The

distance does not exceed 50m on standard CAT 5 cable, for longer distances,

heavy gauge cable should be used1

For a CAT 5 cable exceeding a distance of 50m, separate power supplies

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

3.3 Defining EDID

The TP-121EDID,TP-123EDID,TP-125EDID, and PT-110EDID include:

•EDID Capture - Copies and stores the EDID from a display device

The Extended Display Identification Data (EDID

) is a data-structure,

provided by a display, to describe its capabilities to a graphics card (that is

connected to the display’s source). The EDID enables the graphic source to

“know” what kind of monitor is connected to the output. The EDID includes

the manufacturer’s name, the product type, the timing data supported by the

display, the display size, luminance data and (for digital displays only) the

pixel mapping data.

3.4 Recommendations for 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 and position your Kramer transmitters

away from moisture, excessive sunlight and dust

4 Your TP-121EDID XGA / Audio Line Transmitter

The TP-121EDID is an XGA / audio stereo line transmitter. It receives an

XGA signal and an unbalanced stereo analog audio signal and transmits them

over CAT 5 cable to a receiver

, converting the unbalanced stereo analog

audio signal to digital audio (S/PDIF) stream before transmitting, thus

preserving the quality of the audio signal.

When the TP-121EDID is connected to a display device and the EDID

CAPTURE button is pressed, the TP-121EDID reads and stores the EDID

(Extended Display Identification Data) from the display device. The display can

be disconnected and later reconnected without rebooting the operating system.

3 For example, the Kramer TP-122 XGA / Audio Line Receiver

Your TP-121EDID XGA / Audio Line Transmitter

In particular, the TP-121EDID:

•Has a transmission range of more than 300ft (more than 100m), and a

20kHz audio bandwidth with an S/N ratio that exceeds 80dB on the same

transmission range

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

•Is 12V DC fed

4.1 Connecting the TP-121EDID XGA / Audio Line Transmitter

You can use the TP-121EDID together with the TP-122 XGA / Audio Line

Receiver1

Before connecting the transmitter and receiver system you can acquire the

EDID from the display or set the system to the default EDID, see section

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-122

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

2. On the TP-122, 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).

. Alternatively, you can connect an XGA source to the

XGA INPUT 15-pin HD (F) connector, and a separate audio source to the

AUDIO IN 3.5mm mini jack.

3. Connect the LINE OUTPUT RJ-45 connector on the TP-121EDIDto the

LINE IN RJ-45 connector on the TP-122, via CAT 5 cabling (with a range

of more than 300ft (>100m)), see section 8.

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

adapter to the mains electricity on both3

5. On the TP-122:

the TP-121EDID and the TP-122.

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 necessary, set the H SYNC and V SYNC switches

the video output signal level and/or cable compensation

equalization level, if required 5

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

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

5 By default, both switches are set down (for negative V SYNC and H SYNC polarity)
