LAWO POWER CORE - GPIO over Audio channels (GT In;Out)

Power Core User ManualVersion: 6.6.0/3342/539
19. GPIO
19.6 GPIO over Audio channels (GT In/Out)
GPIO-over-Audio, also known as GT In/Out, works by exchanging GPIO signals across a Digital Audio link.
The physical audio link must be either MADI or AES3, and must not use sample rate conversion (otherwise the
GPIO data will get scrambled). Inputs and outputs assigned to GT signals must be set to Transparent mode.
Also, due to the processing required, changes of logical states must not be faster than 100ms.
GT In/Out elements can be added to the "GPI/O" branch of the 'Tree Definition'. Each element supports 64 GT
channels, each of which can transmit 8 GPIO-bits.
GT In 1 to 64 Parameters
GT In N
Reference name for the GT input.
Audio
Assigns the audio input to be used to receive GPIO data.
Matrix Enable
This checkbox enables matrix control of the GT input. See Matrix Enable.
