3 Overview
This section describes:
The TP-305A UXGA - Audio - RS-232 Line Receiver / 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-305A UXGA - Audio - RS-232 Line Receiver / DA
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 3.2).
In particular, the TP-305A:
Has a resolution of up to UXGA
Has a UXGA output on a 15-pin HD computer graphics video connector
Includes a digital audio output (S/PDIF) on an RCA connector and an
analog audio output on a 3.5mm mini jack
Has a transmission range of up to 300ft (up to 100 meters) over STP cabling
Can change the polarity of the encoded H and V Sync for video (UXGA)
Includes EQ. and LEVEL controls for the video (UXGA) output
3.2 About the Power Connect Feature
The Power Connect feature of the TP-305A lets you power the transmitter /
receiver(s) system by connecting just the TP-305A 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
2
.
For a CAT 5 cable exceeding a distance of 50 meters, separate power supplies
should be connected to the transmitter and to the receivers simultaneously.
1 For example, the Kramer TP-121, TP-123 or TP-45
2 CAT5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

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.
In general, it is recommended to use shielded twisted pair (STP) skew-free
Kramer cable BC-SXTP for transmitting VGA signals (for example, for
TP-305A systems), and shielded twisted pair (STP) non-skew-free Kramer
BC-STP cable for digital signals.
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-305A 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
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
