Offline configuration –user can select which CAN data can be read from LV-CAN200 need to
be sent to server without connection to adapter. Please note that parameters depend on vehicle
manufacturer and vehicle model. Please for further information check “Light Vehicles Can adapter
supported cars” document.
There are two types of operations with CAN data elements:
Monitoring of CAN bus data
CAN bus data event capturing
Monitoring method is used when user wants to receive CAN data on regular basis, for
example every 20 seconds.
Event functionality is used to store additional AVL packet when state of CAN element is
changing. For example Speed changes, low fuel level, engine temperate, etc.
Send data to server field –allows enabling CAN element so it is added to the AVL data packet
and sent to the server. By default, all CAN elements are disabled and FM1100 records only GPS
data.
It is possible to set CAN message priority: On Low Priority, On High Priority, and On Panic.
Regular packets are sent as Low priority records. When low priority event is triggered, FM1100
makes additional record with indication what was the reason for that was CAN element change.
When High priority is selected, module makes additional record with high priority flag and sends
event packet immediately to the server by GPRS. Panic priority triggers same actions as high
priority, but if GPRS fails, it sends AVL packet to server using SMS mode if SMS is enabled in SMS
settings.
Data Acquisition Type –defines when to generate event –when value enters defined range,
exits it or both, also is possible to select event which you want to generate then you change
values, like crossing both values in high and low levels (Hysteresis).
High and Low levels –defines CAN value range. If CAN value enter or exits this range,
FM1100 generates event by “Data Acquisition Type” settings. Figure 6 show example of FM1100
CAN configuration.
