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 (that can be embedded when the S/PDIF ANALOG Selector
Button is set to the analog state). It transmits to up to five receivers (via CAT
5 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 300ft. (more than 100 meters) over
UTP cabling.
Can power the receivers over the same CAT 5 cable, and is 12V DC 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 CAT 5 cable, for longer
distances, heavy gauge cable should be used
1
.
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 CAT 5 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)
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 UTP skew-free cable, Kramer
BC-XTP, is intended for transmitting VGA signals and recommended for this
pair of machines. (Our non-skew-free cable, Kramer BC-STP, is intended for
digital signals.)
The compliance to electromagnetic interference was tested using STP cables,
therefore we recommend 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.
3.4 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
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

This section describes how to:
Connect the TP-205A (see section 5.1)
Connect an additional TP-205A (see section 5.2)
Wire the CAT 5 LINE IN / LINE OUT RJ-45 Connectors (see section 5.3)
