To enable the freezing coordinates function when the vehicle ignition is switched off, it is
necessary to connect to the analogue input a circuit being under voltage when the ignition is on.
This mode activation and input selection are performed by the «
INSTATIC
» command. For the
analogue input used it is necessary to set values of the logical one «
INTRUE
» and the logical zero
«
INFALSE
». In this way, when the ignition is off, an event will be formed in the input and the
coordinates freezing will be initiated.
Switching coordinates freezing on and off during short-term stops is performed by the
«
PSTATIC
» command. This method does not require extra signal connection to the tracker but
does not exclude a slight coordinates dispersion in adverse conditions for receiving signals from
satellites.
6.5 Using the microSD memory card as a “black box”
The tracker allows using the microSD memory card as a “black box” for saving data
transmitted to the telematic server. For this, it is necessary to put the memory card in the holder
and send the «
SDLOG
» command. After this, the terminal will be rebooted. It is possible to save 8
million events per each 1 GB of the card. Therefore, it allows saving almost an unlimited route.
The procedure of data extraction to the server is feasible depending on time and relevance. The
procedure is set by the «
SERIAL»
command.
7 Extra equipment connection
7.1 Analogue inputs
Analogue inputs might be used for analogue sensors connection and voltage level measuring.
Each analogue input might be interpreted as a discrete one.
IN0 input features:
Voltage measurement range: 0-6,6V.
Discreteness (sensitivity): 6mV
The minimum input resistance: 110kOhm
IN1 input features:
Voltage measurement range: 0-13,3V.
Discreteness (sensitivity): 13mV.
The minimum input resistance: 110kOhm.
IN2-IN5 inputs features:
Voltage measurement range: 0-36,6V.
Discreteness (sensitivity): 36mV.
