GPI Page
This page sets up frame-wide GPI numbers to trigger dedicated module functions.
If a GPIO system module detects a GPI input, it puts the associated GPI number on the CAN bus. Each frame module watches for
these GPI numbers and performs the pre-programmed action if it reads that number on the CAN bus.
Preset 1–8
A GPI input can be set to recall a preset.
Mute 1–4
A GPI input can be set to mute selected channel.
Phantom 1–4
A GPI input can be set to enable phantom power for selected mic.
Line 1–4
A GPI input can be set to enable a 10-dB input pad for selected channel.
Do not assign the same GPIO numbers to different functions because this incorrectly triggers multiple functions.
