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
