CHAPTER 3: Key Audio Design Features What's the difference between the four linkable controls in each event? Each toggle and selector event has four possible links. Each command event has three possible links. Here's how they differ: 1. Event Value link - The event value/status is always grayed-out because it is a read-only control. This means that it only shows you if the event is active or inactive. When checked or selected, it means that there is a match between the current clock settings and the settings configured for the event. Therefore, when you link to the Event value, you are providing an indicator or monitor that displays an events status. Since the clock settings and event settings are the only thing that drive the event active checkbox, you can't use this link to allow an end user to activate or inactivate an event; this is what the Active Trigger & Inactive Trigger links provide. 2. Active Trigger link - Since the event value link is solely and always a monitor showing an event's state, to allow both the clock and end users to activate events, link to the Active Trigger link. This is useful when end users need to start events before the configured event time - this provides a "start the meeting now" button to activate the event. 3. Inactive Trigger link (not applicable/available in command events) - To manually end an event that is active, link to the Inactive Trigger link. This allows event deactivation from a button, DR2, DR3, DR6, web control page button or a 3rd-party button. 4. Event Enable link - The Enable link conceptually unplugs the clock from the event. This is useful to skip or ignore a given event because it turns off the clock feed so the event is disabled from knowing the time. You might need this when configuring or testing events - especially when making changes or tweaks to a live HAL system that is in use. 153
