Audio Conversion
Figure 29 shows a standard installation with DVI video and an audio input. The
DVI 201 A D Tx converts the video input into two proprietary TP outputs. The Tx outputs
the audio directly on a captive screw connector.

Figure 29. Typical Installation
Modulated IR Pass Through Application
Figure 30 shows an installation in which the Tx/Rx pair sends a modulated infrared (IR)
signal across the link. On the Tx side, control system is connected to the Tx pin (the
modulated IR signal) and the Gnd (signal ground) on the transmitter. An IR emitter is
connected to the Tx and Gnd receiver output.
