The TP-46Component/XGA – Audio Receiver features:

•YUV5 output on 3 RCA connectors and a computer graphics output on a 15-pin HD (F) connector

•Digital audio output (S/PDIF) on an RCA connector and a stereo analog output on a 3.5mm mini jack

•The Power Connect feature where one unit can power the other over the same twisted pair cable (see section 3.1)

•H and V Sync polarity switches for computer graphics

•EQ. and LEVEL controls

•A twisted pair output for transmitting the signal to an additional receiver

•12V DC power

3.1About 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 twisted pair cable. For longer distances, heavy gauge cable should be used1. 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 twisted pair cable exceeding a distance of 50m, separate power supplies should be connected to the transmitter and to the receiver simultaneously.

1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
