Application Examples
Audio Conversion
Figure 28 shows a standard installation with HDMI video and an audio input. The
HDMI 201 A D Tx converts the video input into two proprietary TP outputs. The Tx
outputs the audio directly on a captive screw connector.

Typical Installation
Modulated IR Pass Through Application
Figure 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.
