3 Overview
This user manual describes the following Kramer TOOLS:
- TP-104/TP-104HD XGA Line Transmitter/DA is a line transmitter/1:4 DA that receives an XGA signal and transmits it over four CAT 5 cables to appropriate receivers (see section 4)
- TP-105/TP-105(HD) CAT 5 Line Driver/DA receives a CAT 5 input ^1 and distributes it to two identical outputs (see section 5)
- TP-121 XGA/Audio Line Transmitter and the TP-122 XGA/Audio Line Receiver (see section 6)
- TP-123 XGA/Audio/Data Line Transmitter and the TP-124 XGA/Audio/Data Line Receiver (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 - Recommendations for achieving the best performance, see section 3.3
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. 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 supplies should be connected to the transmitter and to the receiver simultaneously.
3.3 Recommendations for Achieving the Best Performance
To achieve the best performance:
- Use only good quality connection cables ^2 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 product 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 the unit
Warning:
Disconnect power and unplug unit from wall before installing or removing the device or servicing unit

7.2 Your TP-124 XGA/Audio/Data Line Receiver
The TP-124 is a high-performance receiver obtaining the computer graphics signal/audio/control data from the Kramer TP-123 via UTP cabling at its CAT 5 Line input. The TP-124 outputs a computer graphics signal, an unbalanced stereo analog audio signal, a converted digital audio (S/PDIF) signal and RS-232 control commands. The unidirectional (TxD) RS-232 interface makes it possible to control virtually any devices over a transmission range of more than 300ft (more than 100m) over UTP cabling. The TP-124 can power or be powered by the TP-123 transmitter over the same CAT 5 cable.
In addition, the TP-124 features:
• Level and EQ. control for the XGA signals
- The capability to change the polarity of decoding H and V Sync
- 24 bit 48kHz S/PDIF digital audio that supplies the highest quality audio
- Is 12V DC fed

8 Connecting the XGA/Audio Line Transmitter/Receiver
You can use the TP-121 and TP-122 to configure an XGA/Audio Line-to-Twisted Pair Transmitter and Receiver system.
To connect the TP-121 XGA/Audio Line Transmitter with the TP-122 XGA/Audio Line Receiver, as the example in Figure 13 illustrates, do the following:
- On the TP-121, 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)1. 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.
- 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).
- Connect the LINE OUTPUT RJ-45 connector on the TP-121 to the LINE IN RJ-45 connector on the TP-122, via UTP cabling (with a range of more than 300ft (>100m)), see section 8.1.
- Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity on both ^2 the TP-121 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.
- On the TP-122:
- Adjust ^3 the video output signal level and/or cable compensation equalization level, if required
- If necessary, set the H SYNC and V SYNC switches ^4 , on the underside

- OUT 2 to the LINE IN RJ-45 connector on the TP-120 Unit II
-
OUT 3 to the LINE IN RJ-45 connector on the TP-120 Unit III
■ OUT 4 to the LINE IN RJ-45 connector on the TP-120 Unit IV -
On the four TP-120 units, connect the:
-
XGA OUT 15-pin HD (F) connector of Unit I to the XGA acceptor (for example, Display 1)
- XGA OUT 15-pin HD (F) connector of Unit II to the XGA acceptor (for example, Display 2)
■ XGA OUT 15-pin HD (F) connector of Unit III to the XGA acceptor (for example, Display 3) -
XGA OUT 15-pin HD (F) connector of Unit IV to the XGA acceptor (for example, Display 4)
-
On each of the five Kramer TOOLS, connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity.
The signal from the XGA source is transmitted via the four CAT 5 cables, decoded and converted at the each of the XGA OUT 15-pin HD (F) connectors to the XGA acceptors.
- On each of the five Kramer TOOLS:
- Adjust ^3 the video output signal level and/or cable compensation equalization level, if required
