To use Manual CAN commands functionality user should select Manual CAN Commands tab in Configurator. Afterwards, user will be able to configure CAN parameters in Manual CAN commands settings tab.

Manual CAN Commands

The main benefit of using Manual CAN command functionality is that the user is able to send data via CAN BUS without requiring additional CAN protocol development from the device's firmware side if vehicle should take an action with equipment connected via CAN line. To send command via CAN line with this functionality, the user must have:

  • FMC650/FMM650/FMB641 device
03.00.13.Rev.05 or newer firmware (for FMC650/FMM650) 03.01.00.Rev.00 or newer firmware for (FMB641/FMC650/FMM650)
  • Transport or equipment with CAN interface which works via J1939 protocol
  • Transport or equipment CAN communication protocol (with information about frames, parameters, ID‘s, Baudrate)

Manual CAN Command I/O settings

User can configure up to 10 Manual CAN I/O commands by setting CAN Type, Data mask, CAN ID, Request Period, Request Data Length parameters. Each CAN I/O has its own parameters and can be configured independently.

Functionality will work only when Ignition will be ON

Baudrates are configurable in CAN \ Tachograph settings for connected CAN line which could be CAN1 or CAN2

  • Manual CAN Type parameter - defines which CAN ID type will be received and requested (Standard - 11bit, Extended - 29bit).
  • CAN ID/PGN - depends on CAN Type parameter and defines which CAN ID will be received by device
  • Data Mask - defines which data mask will be applied to received CAN data. CAN Data mask parameter is 8byte hex value. Displayed data value will be Received Data Value AND Data Mask. In other words - Data Mask parameter defines which data will be taken from the specific frame.
  • Request data length - defines data length of requested ID.
  • Send type – Could be selected with three different choices:
    • Once – it defines request will be sent once if Run On Startup is enabled
    • Periodic – it defines the request via CAN will be sent by set period in ms, for configured send count.
    • Response – it defines to which MANUAL CAN value will be sent.
  • Run On Startup – Enable/disable defines if on Ignition startup will be needed to send a command.
