Real-time Clock
The real-time clock is only used for time of day and
calendar functions. It can be set automatically by PTP to
other drive.web devices, automatically upon discovery in
the
drive.web savvy
software, per preferences, or via
SNTP network time server protocol. See the
savvy
user
manual for details.
The real-time clock will be maintained for approximately
24hrs after supply power loss with no backup battery.
Alternatively the clock can be powered by the USB port.
Lithium button cell battery, CR2032, 3VDC, commonly
found in convenience stores, is not provided from the
factory due to shipping restrictions.
