1.2.8 History Buffer
The D9068 has a history buffer that
retains up to 100 events. Each event is
tagged with the date and time of
occurrence. This buffer can be viewed
when a D7033/FMR-DACT-KEYPAD is
attached to the D9068. When the buffer
is full, old events are discarded to
make room for new events. A watchdog
reset is entered in the buffer and does
not reset the buffer.
The history buffer can clear
when the system loses power
for more than 5 min.
