Impera controllers react to state changes made to system components, except for those changes initially triggered by the controller itself.
If the controller sends a command to an HDMI switch, setting it to select INPUT 3, the controller will not react to or register the response feedback from the switch. In this example, when the switch responds to the GET commands by signaling that INPUT 3 is now selected. However, the controller will react when the switch is subsequently changed to INPUT 1 by an outside command source. The controller will then execute the functions or sequences specified in the Action pane of the feedback section in your Biamp Project Designer configuration.
For functions or sequences that must be continually available for triggering, the best approach is to map these functions directly to the buttons you have configured to trigger the input change. Using the previous example, an input change from an outside source (not the controller). The device feedback can then be used to trigger a "Press Button" on these buttons. This ensures the interface will always be in sync, providing an effective way of configuring your system.
Manually making a selection will not trigger these functions due to the way the control system manages feedback.
