Power Up Operation
When power is first applied to the AM-4 Digital Audio Machine, it briefly blinks the
Status LED green. It then checks to see if a new firmware file exists, or if a track or
Play List should be played, according to the following priority:
Note: The Fault relay
output will be closed on
power-up indicating
that power was lost. It
will open as soon as a
valid command is
issued.
•
Check the Compact Flash card for a OS.NEW file. If found, the firmware is
updated and the file is renamed to OS.SAV.
•
Process and execute any real-time schedule operations.
•
Play any track or Play List that is hardwired at the Control Connector.
•
Play track or Play List 0 from the media
The first condition detected will be processed. Successive conditions are ignored. If
more than one file has the same number, the first file found will be used.

Compact Flash card, if it is not freshly formatted, before going further.
