5.6 Setting the fixation (freezing) of coordinates during the parking
The margin of error might cause a slight coordinates dispersion during a long-term parking of
the vehicle. To prevent this effect the coordinates freezing function can be used in the beginning of
the parking. This mode is activated automatically when the discrete level is changed at the analog
input, or at a speed below the set level. Simultaneous use of both ways of coordinates fixation is
impossible. The tracker records the coordinates in the mode that was last configured.
5.6.1 Coordinates fixation by the ignition
To activate the function of fixing the coordinates with the vehicle ignition off, it is necessary
to connect to the analog input a circuit being under voltage when the ignition is on. Activate a discrete
mode for this analogue input and set the values range of voltage level for the logical one as
"INTRUE
" and for the logical zero
as
"INFALSE"
.
Afterwards select coordinates fixation mode “by
the ignition”. Thus, when the ignition is off, coordinates fixation will be initiated by an event formed
at the input.
•
Examples of using
INSTATIC
command:
Coordinates fixation at 0 in the input AIN0
INSTATIC 0,0
The function is disabled by the command «
INSTATIC 255».
5.6.2 Coordinates fixation by speed
In such a mode the coordinates fixation is done automatically if the tracker registers the speed
beyond the set threshold. The precision of this function depends on the precision of the coordinates
determination. Thus, in case of bad signal receipt from GLONASS/GPS satellites, the coordinates
fixation by the speed might be not stable.
The function of fixing coordinates by speed is activated by the command «
SPEEDSTATIC
X»
, X is the speed (km / h), below which the coordinates are fixed. The function is disabled by the
«
SP
EEDSTATIC 255»
command
.
SPEEDSTATIC 3
is set by default.
Selecting rather high-speed threshold may result in improvement of function performance
during parking, but may cause data loss when driving at the beginning or when driving at a low
speed.
5.7 Operation mode
The tracker has got
two modes of routes record: «Tracker» and «Beacon». The working mode is
set by
BMODE
command. Mode “Tracker” is set by default.
