3 Overview
Overview
The TP-305A UXGA - Audio - RS-232 Line Receiver/DA receives a CAT 5
signal from a transmitter
1
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 graphi cs 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 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 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 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 suppli es
should be connected to the transmitter and to the receiver simultaneously.
3.2 Shielded Twisted Pair (STP)/Unshielded Twisted Pair (UTP)
recommend that you use Shielded Twisted Pair (STP) cable. There are
We
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 cre ate electrical interference.
However, since the use of UTP cable might cause inconform ity 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

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.
