Parameter name Description Units
serial_number Unique identifier of the tracker
counter Counts the messages sent by the device from 1 to 4294967295. After reaching 4294967295, the counter resets to 1
nickname Name assigned to the device (up to 10 characters)
rssi Received signal strength, ranging from 0 to 31, where 99 indicates no signal.
hdop Quality of horizontal location provided by GNSS, with lower values indicating greater accuracy
ignition Vehicle ignition status, 1 for on and 0 for off.
backup Indicates whether the data was sent successfully (0) or whether it failed and was stored for retransmission (1)
engine_hour The total engine running time in hours.
odometer The total distance traveled by the vehicle in km.
event_id The unique identifier of each event. This code is used to specifically identify the type of event that occurred
event_status Indicates the possible states in which the event can be recorded.
event_name Indicates whether there is any additional information associated with the event. This field is especially useful for events that require additional data, such as driver or passenger identification, which is stored in the 'name' field. It is only sent for certain types of event, as described in Table 4 in the documentation.
vin_voltage Voltages in mV of the tracker power supply
int_pwr Voltages in mV of the internal battery
operator Name of the telephone operator, transmitting only the first four characters to save data
cell_tech Type of the last network technology to which the tracker connected, represented numerically
shipping_tm Date and time of data sending
gnss_fix GNSS connection status, indicating whether the signal is available and its type
io_status Represents the operational status of each Input/Output (I/O) pin on the device. States are coded as '1' for 'on' and '0' for 'off'. This includes pins such as post-switch, power down, input 2 and output 2, allowing detailed monitoring of the relevant hardware activity. See Table 2 in the documentation for more details
can_odometer Measures the total distance traveled by the vehicle, in kilometers km
can_engine_hour Records the total operating time of the vehicle's engine in hours hours
can_speed Measures the vehicle's current speed in km/h km/h
can_rpm MeasuRecords the revolutions per minute of the vehicle's engine
can_on_off The status of a CAN system parameter. Parameters include parking brake, brake, clutch, air conditioning, seat belt and windshield wiper. A bit of '1' means that the parameter is on or activated, while a bit of '0' means that it is off or not used. For more details see Table 6 in the documentation.
can_accel_pedal Indicates the percentage of pressure applied to the accelerator pedal from 0 to 100
can_fuel_level_unit Indicates the unit of measurement for the fuel level (L or %)
can_fuel_level Indicates the current fuel level in the vehicle's tank in % or L
can_range Estimates the distance the vehicle can travel with the remaining fuel, in kilometers km
can_fuel_consumption_unit Indicates the unit of measurement for fuel consumption: L/h (H) or km/L (K)
can_fuel_consumption Measures the vehicle's fuel consumption rate in L/h (H) or km/L (K).
can_fuel_used Quantifies the total fuel used by the vehicle throughout its useful life, in liters L
can_oil_temp Records the engine oil temperature in degrees Celsius degrees Celsius
