above this speed even if the vibration sensor is below
Level for Sleep.
Wake up sensitivity level (0-255)
- indicates the vibration sensor level below which the vehicle is
considered stationary.
Sensor filter settings
- This feature is designed to stop GPS drifting when the vehicle is parked
for several hours. Keep a note of the original settings before modifying these values.
Thresholds and Threshold times
- see below
Period [seconds]
- do not record position after the vehicle has been stationary for more that this
amount of time.
Activity level
- indicates the vibration sensor level below which the vehicle is considered
stationary.
Sleep – sensor was quiet and positions was not stored
L1 (Treshold1)
- level from motion sensor which will activate the VTU
- level of actual sensor signal must be higher than L1
T1 (TrTime1)
- ignore time ( positions are not stored )
L2 (Treshold2) / T2 (TrTime2)
- The sensor level must increase to L2 in time T2 to re-
activate position recording, else the VTU goes back to Sleep.
L0 (Activity level) / T0 (Period) - After an increase to the L2 threshold starts time T0. In this
period the level of signal from the sensor must be higher than L0 for VTU to store positions. If it's
not reactivated in time T0 VTU goes to Sleep state.
Units:
All thresholds are in range ( 0- 255 )
All times are in seconds ( s )
Data calls settings
- if this is enabled the unit will not answer calls from any other numbers than
the three listed here. This security feature is useful if you want to make sure that nobody can dial
into your unit from another location. But be careful to set the right numbers otherwise you will not
be able to dial in yourself.
Answer all calls (data and voice)
- this turns the number filtering off completely. It is only
necessary if you want to dial the VTU from a line that has the "number withheld" service enabled.
In most other cases it is best not to enable this setting as it also disables the local geofence
function.
Modem answer timeout
- modifying this value can sometimes increase reliability with certain
network operators. Only change with caution. In most cases it should be left as set by the
manufacturer.
