Overview  
The TP-305A UXGA - Audio - RS-232 Line Receiver/DA receives a CAT 5  
signal from a transmitter1 and distributes it to up to five other receivers (via  
CAT 5 cables). The TP-305A also decodes the CAT 5 signal and distributes  
it to a UXGA output, an analog audio output, a digital audio output and an  
RS-232 output.  
The TP-305A serves as a power center that can distribute power to both the  
transmitter and the connected receivers (see section 3.1).  
In particular, the TP-305A features:  
Resolution of up to UXGA  
UXGA output on a 15-pin HD computer graphics video connector  
Digital audio output (S/PDIF) on an RCA connector and an analog  
audio output on a 3.5mm mini jack  
A transmission range of up to 300ft (up to 100 meters) over STP  
cabling  
Changeable polarity of the encoded H and V Sync for video (UXGA)  
EQ. and LEVEL controls for the video (UXGA) output  
To achieve the best performance:  
Use only good quality connection cables2 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 TP-305A  
away from moisture, excessive sunlight and dust

Overview  
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 on standard CAT 5 cable. For longer distances, heavy gauge  
cable should be used1. 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.  
3.2 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.  
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

Receiver/DA  
You can use the TP-305A with a UXGA - Audio - RS-232 Line Receiver/DA  
such as the Kramer TP-1232. You can connect a single TP-305A to up to five  
receivers, and up to five TP-305A units can be connected to increase the  
number of outputs to 25.  
5.1 Connecting a Single TP-305A  
To connect a TP-123/TP-305A UXGA – Audio - RS-232/Line  
Receiver/DA system3 as illustrated in the example in Figure 3, do the  
following4:  
1. On the TP-305A, connect the:  
ƒ UXGA OUT 15-pin HD computer graphics video connector to the  
UXGA acceptor (for example, a plasma display), and the AUDIO  
OUT ANALOG 3.5mm mini jack connector to the analog audio  
connector on the acceptor. If required, connect the RS-232 G and  
TX terminal block connector to the RS-232 port on the acceptor  
ƒ LINE OUTPUT RJ-45 connector on the TP-123 to the LINE IN  
1 By default, both switches are set to NORM.  
2 Refer to the separate user manual, which can be downloaded at: http://www.kramerelectronics.com

5.2 Connecting Several TP-305A Units  
You can connect up to five additional TP-305A units via the LINE  
OUTPUT RJ-45 connectors on the first unit. The number of TP-305A units  
that can be connected depends upon the quality of the input signal that you  
require and the distance between the machines.  
In the example illustrated in Figure 4, a TP-305A unit is connected to three  
additional TP-305A units via the LINE OUTPUT RJ-45 connectors. Each  
of the three connected TP-305A units can distribute the signal to five  
receivers. The system, in total, distributes the signal to 17 receivers.  
To connect an expanded UXGA – Audio Line Receiver/DA system, do the  
following:  
1. Connect a transmitter to the LINE IN RJ-45 connector of the first TP-305A.  
2. Connect the LINE OUTPUT 1 RJ-45 connector of the first TP-305A to the  
LINE IN RJ-45 connector of the second TP-305A.

5. Connect the LINE OUTPUT RJ-45 connectors of each TP-305A unit, to  
the LINE IN RJ-45 connectors of the appropriate receivers, as illustrated in  
6. On each TP-305A unit, connect the 12V DC power adapter to the power  
socket and connect the adapter to the mains electricity.
