GPIO Overview
The GPIO interface allows external controllers to trigger pre setup activities or functions such as Scenes or Message Playbacks. There are six standard
and one High-Priority input contact closure or voltage triggers. The High Priority input has additional settings specifically for Public Alert Messaging
or where emergency systems need to be coordinated with the audio system. There are two GPO – voltage trigger outputs that internal faults can be
selected to trigger. Or, they can be configured in Scenes to start a power sequencer, projector and screen, or start/stop a third-party voltage activated
system/device.
