LOCK
A battery buffered internal real time clock is available for time stamping data, start and stop network
upload and others controls. The battery is a rechargeable “memo
-
buf” cell
- specifically designed for RTC
operations. During regular operation, the battery is recharged over a 48h period. During non-operating
times (= supply power off) , the date and time settings are maintained.
If the Avisaro device is networked, a network time server (SNTP) can be used to set time and date
automatically.
If a Avisaro GPS receiver is connected, the RTC can be set using satelite time.
It is possible to define time zones settings.
