Audio Line Level Input Connections
1. Remove the 100 Ohm termination resistor from the C+ to C- terminals.
2. Connect the audio line level source to the Audio_In+ (C+) input terminal.
3. Connect the audio signal ground to the Audio_In- (C-) input terminal.
Audio Line Level Output Connections
1. Connect the audio line level input of the audio output device (for example, an amplified
speaker or a PC line level input) to the Audio_Out+ (RXD) output terminal.
2. Connect the audio line level output signal ground to the Audio_Out- (TXD) output
terminal.
