The Triggers

6.7.2System Inactivity Example

In this example, the Timer trigger is used to perform a sequence of actions if no signals are fed into the AV room system for a predefined time period (for example, 20 minutes, see Figure 74). A switcher (for example – the Kramer VP-411DS) will send out a dedicated serial command once all PC sources are disconnected. We will use this command to trigger a 20 minute timer. Each action list will start with a command to stop this timer. In the System Inactivity timer we will shut down the display device and perform other shut off tasks.

To indicate inactivity, you have to add a “Stop” trigger prior to the sequence of actions and a “Start” trigger upon completion of the actions sequence.

This setup includes two steps:

Step I: Define the Timer Trigger (which will be used for all the triggers)

Step II: Define the Button (and other) triggers
