5 BOLERO-LT APPLICATION INTERFACE
5.1 Power supply
The power supply for the BOLERO-LT terminal has to be a single voltage source
within the range
V
+IN
=+10.8V...+32.0VDC
. It must be able to provide sufficient
current. The operating voltage (V
+IN
and GND) is protected from reverse pole
connection and
against voltage spikes, but not against over voltage.
NOTE: Operating voltage range must never be exceeded; care must be taken in
order to fulfill min/max voltage requirements.
5.1.1 Power supply pins (3 and 4) on the 6-pin connector
The +
IN
pin on the 6-pin connector is dedicated to connect the supply voltage, GND
pin is for grounding. The +IN and GND pins serve for charging the internal battery (if
available) and powering the BOLERO-LT device.
The power supply for the BOLERO-
LT is capable of utilizing current ranging from
V
+IN
=+10.8V...+32.0VDC
designed
for automotive application.

Positive operating voltage.
For security reason, it is recommended to integrate
externally a 2A fuse link between interconnection plug (6-
pin connector) and d.c.-power source (see Fig 19).

5.1.2 Automatic shutdown
Automatic shutdown takes effect if:
•
under voltage is detected when battery level (if available) runs low and no
external power
supply connected.
The automatic shutdown procedure is equivalent to the power-down initiated,
i.e. BOLERO-LT logs off from the network and the software enters a secure state
avoiding loss of data.
