3 Overview
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 300feet (more than 100 meters)
over UTP cabling
• Can power the receivers over the same CAT 5 cable, and is 12V DC
fed
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 a CAT 5 cable exceeding a distance of 50m, separate power supplies
should be connected to the transmitter and to the receiver simultaneously.
. 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).
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.
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
