The speed limit is set by sending a command to the tracker:
setspeedevt XXX;
,where:
XXX – speed limit (for example 050 = 50 km/h).
To disable the movement, you must send the command:
vehiclestop;
To enable the movement, you must send the command:
vehicletart;
Configuring the device for working with a CAN bus
«BI 530С TREK» tracking device has the ability to read data directly
from the CAN bus of the vehicle. When connecting the device to the
vehicle’s CAN bus, it is recommended to use a Bitrek CANReader
contactless reader to prevent violation of the insulating sheath of wires.
The device can be configured to read and transfer to the server up
to 10 variables simultaneously. You can read both short 11-bit identifiers
and long 29-bit ones. At the same time, 4 separate tracker parameters
are used to configure reading of one such variable:
PGN
Start Bit
Length (number of bits)
Data reset timeout
A list of all available parameters for CAN settings is presented in
Please note that for the device to successfully receive data from the
vehicle’s CAN bus, you must set the tracker bus speed that corresponds
to the vehicle’s CAN bus speed. The parameter for setting the speed ID
5038 is turned off by default (equal to zero) and if it is connected to the
vehicle’s CAN bus, its mandatory setting is required. Possible parameter
values are given in
An example of setting the tracker to read fuel consumption data is
given below.
Using the description of the FMS standard, we determined that the
necessary data on fuel consumption are broadcast in the last four bytes
of PGN FEE9 (Fig. 9)
IMPORTANT!
On devices with firmware version 1.4.9 and higher, the speed of
the CAN bus is set in bits (setparam 5038 250000).
On devices with firmware version 1.4.7 and below, the speed of
the CAN bus is set in kilobits (setparam 5038 250).
