4.2 Defining the TP-146 UXGA/Audio/Data Line Receiver
The TP-146 is a high-performance receiver that accepts the computer graphics
signal/audio/control data from the Kramer TP-145 via TP cabling at its RJ-45
LINE IN input. The TP-146 outputs a computer graphics signal, an unbalanced
stereo analog audio signal, a converted digital audio (S/PDIF) signal, and bi-
directional RS-232 control commands and data. The RS-232 interface makes it
possible to control virtually any device over a transmission range of up to 200m
