Troubleshooting¶
This chapter helps you quickly identify and resolve common issues with the CANlink® mobile 3600.
For detailed information, see Troubleshooting.
Device is offline¶
Symptoms: Device does not appear in DataPortal; LTE LED off.
Possible causes:
- Power supply not connected or faulty
- SIM card not inserted or inactive
- LTE signal too weak
- Device not provisioned in DataPortal
Solutions:
- Check that the power supply is connected and the device LED is on.
- Verify the SIM card is correctly inserted and active.
- Move the device to an area with better LTE coverage or check antenna connection.
- Confirm the device is provisioned in DataPortal.
No CAN data transmitted¶
Symptoms: CAN messages not visible in monitoring software or DataPortal.
Possible causes:
- CAN bus wiring incorrect
- Termination resistors missing or wrong value
- Baud rate mismatch
- Configuration missing or incorrect
Solutions:
- Verify CAN wiring matches the device documentation.
- Ensure 120Ω termination resistors are installed at both ends of the bus.
- Confirm the CAN baud rate in Proemion Configurator matches the bus.
- Reload or create the correct configuration using the Proemion Configurator.
Incorrect or unexpected signal values¶
Symptoms: Signal values appear wrong in DataPortal or monitoring tool.
Possible causes:
- Wrong PGN/SPN mapping
- Incorrect scaling or offset
- Byte order mismatch
- PDC mapping incorrect
Solutions:
- Verify PGN/SPN assignment in Proemion Configurator matches your CAN system.
- Check scaling factors and offsets for each signal.
- Confirm byte order (endianness) is correct.
- Reassign signals in the PDC file if necessary and re-provision the device.
Firmware or software issues¶
Symptoms: Device not responding; configuration cannot be written; unexpected behavior.
Possible causes:
- Outdated firmware
- Outdated Proemion Configurator software
- Compatibility mismatch between device and configuration
Solutions:
- Update device firmware to the latest version.
- Install the latest version of Proemion Configurator.
- Ensure configuration file matches device model and firmware version.
