Overview

3 Overview

This section describes:

The TP-205A XGA / Audio / RS-232 Line Transmitter / DA, see section

3.1

The power connect feature, see section 3.2

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

section 3.3

Recommendations for achieving the best performance, see section 3.4

3.1 Your TP-205A

The TP-205A is a high performance transmitter. It accepts a computer

graphics input signal, a selectable unbalanced stereo analog audio signal or a

digital audio (S/PDIF) signal, and unidirectional (TxD) RS-232 control

commands. It transmits to up to five receivers (via CAT5 cables).

In addition, the TP-205A:

Has a resolution of up to UXGA

Can be looped to an additional TP-205A transmitter

Has a transmission range of more than 300 ft. (more than 100 meters)

over UTP cabling.

Can power the receivers over the same CAT5 cable, and is 12VDC fed

3.2 About the Power Connect Feature

The Power Connect feature of the TP-205A lets you power the transmitter /

receiver(s) system by connecting just the TP-205A power adapter. The other

units are fed via the cables connecting between the transmitter/receivers. 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

For a CAT5 cable exceeding a distance of 50 meters, separate power supplies

should be connected to the transmitter and to the receivers simultaneously.

1 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

Overview

3.3 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.

3.4 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 TP-205A 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

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.

Configuring the TP-205A

5 Configuring the TP-205A

This section describes how to:

Connect the TP-205A (see section 5.1)

Connect an additional TP-205A (see section 5.2)

Wire the CAT5 LINE IN / LINE OUT RJ-45 Connectors (see section 5.3)

Control via RS-232 (see section 5.4)

5.1 Connecting the TP-205A

You can connect the TP-205A to up to five transmitters. Use it to transmit the

video, audio and RS-232 control signals via CAT5 UTP cable.

To connect the TP-205 as illustrated in the example in Figure 3, do the following:

1. Connect an XGA source (for example, a laptop’s graphics card) to the XGA IN

HD15F connector and an audio source to the ANALOG AUDIO IN 3.5mm

mini jack

, for example, using a Kramer C-GMA/GMA cable (VGA HD15M

+Audio jack to VGA HD15M +Audio jack)

2. Press the SELECT button to select the ANALOG input

3. Connect an RS-232 cable with a DB9 connector at one end to the laptop, and the

other end to the 2 left-hand pins of the terminal block connector

(GND and IN)

on the TP-205A RS-232 port

4. Connect the LINE OUTPUT CAT5 connectors as follows

The LINE OUT 1 RJ-45 connector on the TP-205A to the LINE IN

RJ-45 connector on the TP-46

via UTP cabling

(with a range of

more than 300ft (>100m))

The LINE OUT 5 RJ-45 connector on the TP-205A to the LINE IN

RJ-45 connector on the TP-122

,via UTP cabling

(with a range of

more than 300ft (>100m))

1 Or alternatively to the digital audio S/PDIF IN RCA connector

2 Not supplied. The full list of Kramer cables is on our Web site at http://www.kramerelectronics.com. Alternatively, you can

connect an XGA source to the XGA IN HD15F connector, and a separate audio source to the AUDIO IN 3.5mm mini jack

3 If the digital audio input is selected, release the SELECT button

4 The two right pins (GND and LOOP) can be connected to the GND and IN connectors on an additional TP-205A unit

5 As defined in Figure 6 and Table 4 (see section 5.4)

6 You do not have to connect all the outputs

7 Refer to the separate user manual, which can be downloaded from the Internet at http://www.kramerelectronics.com

8 For details of how to wire a CAT5 LINE IN / LINE OUT RJ-45 connector, see section 5.3
