Audio conversion

Figure 2-28 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.

Modulated IR pass through

Figure 2-29 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.
