The AM-4 Digital Audio Machine has a down-to-the-minute scheduler
based upon its internal real time clock. At any time of day and date of
year, the AM-4 Digital Audio Machine can start or stop playback of
any file or play list, or do whatever it is supposed to at 3pm on January
15th 2009, for example. This functionality is built into a feature called
the
Scheduler .
File Format / Tutorial
The Scheduler uses a text file loaded onto the compact flash of the AM-4 Digital
Audio Machine. The text file can be edited in a text editor, like notepad. The
schedule filename is
schedule.scl.
Events
A schedule contains a list of events. Each event consists of a command usually used
to start or stop playback of a particular file or playlist at a particular time. It
essentially executes the same serial commands used for external control of the AM-4,
except that it does so on a scheduled basis. In fact, any serial command listed in the
Advanced Serial Protocol section of this manual may be used as an event in the
Scheduler.
Each command event has a variety of parameters that can be applied to it in order to
customize the AM-4’s behavior. In order to understand how you specify command
events in the AM-4, let’s start with a simple example and build it to a more feature-
rich example.
