6. FOX3-2G/3G/4G APPLICATION INTERFACE
6.1. Power supply
The power supply for the FOX3-2G/3G/4G devices has to be a single voltage source of V
+IN
= +10.8 V...+32.0 V DC. The
operating voltage (V
+IN
) has to be applied permanently to the FOX3-2G/3G/4G devices and able to provide sufficient
current of up to 1.5 A (pulse).
The operating voltage (V
+IN
and GND) is protected against voltage spikes and reverse polarity, but NOT protected
against continuous overvoltage.
NOTE: Operating voltage range must never be exceeded; care must be taken in order to fulfill min/max
voltage requirements.
6.1.1. Power supply pins (1 and 2) on the 8-pin connector
One +IN pin on the main 8-pin port is dedicated to connect the supply voltage, and the GND pin for grounding.
Both +IN and GND pins serve for charging the connected backup battery (option) and also for powering the FOX3-
2G/3G/4G devices. FOX3-2G/3G/4G have an automatic power ON-function when external power is applied and no
battery connected. The power supply for the FOX3-2G/3G/4G ranges from V
+IN
=+10.8 V... +32.0 VDC allowing direct
connection to vehicle power system.

Positive operating voltage.
For security reason, it is recommended to protect the input voltage
by and external 2A fuse between the device and d.c.-power source
(see Fig 15).

Ground (should be isolated from the vehicle grounds when the
device is going to be installed in a vehicle)
6.1.2. Automatic shutdown
Automatic shutdown takes effect if:
• under voltage is detected (internal battery level runs below the nominal voltage and the external power supply is
disconnected).
6.1.3. Power saving
SLEEP mode reduces the functionality of the modules of the FOX3-2G/3G/4G devices to a minimum and, thus,
minimizes the current consumption to the lowest level. The FOX3-2G/3G/4G can be set into the sleep mode using the
command $PFAL,Sys.Device.Sleep[
ChargeSleep,Doze] with one or more parameters listed in the table below. Following
SLEEP modes are supported by the FOX3-2G/3G/4G devices:
Modes
Description
Example $PFAL,Sys.Device.Sleep=IGN+Ring+Timer=1:20:00
$PFAL,Sys.Device.ChargeSleep=IGN
$PFAL,Sys.Device.Doze=Ign+Wakeup=23:20:00
IGN
Device wakes-up when a rising edge (Low to High signal) on the IGN pin is detected.
Ring
Device wakes up on incoming voice call or SMS.
Wakeup=15:30:00
Device wakes up at the set wake up time.
Timer=1:20:00
Device wakes up when timeout has expired.
Motion=200
Device wakes up when the set motion value is exceeded.
ExtPwrDetect
Device wakes up when external power connection is detected.
ExtPwrDrop
Device wakes up when external power disconnection is detected. For battery powered devices, the device
wakes up when the battery voltage drops below the minimum.
GPS
Sets the GPS receiver into the Hibernate state
CAN*
Device wakes up when activities on the CAN bus interface are detected. This wakeup condition is
