TJA1020T-CM Communication Glitches: What to Check First
T wiringJAT/CM. If it's operating above the recommended temperature range (usually between -40°C to +125°C), ensure proper cooling or ventilation.
If overheating is detected, consider adding heat sinks or improving airflow.Summary of Solutions:
Power Supply: Check for stable voltage and remove fluctuations. Bus Wiring: Ensure secure connections and use twisted pair cables. Termination Resistors : Install two 120-ohm resistors at the bus ends. Baud Rate: Verify that the baud rate is the same across all devices. Bus Load: Monitor and reduce the number of devices if necessary. EMC Protection: Use shielded cables and avoid interference sources. TJA1020T/CM Configuration: Double-check the device’s mode and settings. CAN Controller/Software: Ensure correct software handling of CAN communication. Temperature: Ensure the device is not overheating and has proper cooling.By following these steps, you can efficiently diagnose and solve communication glitches with the TJA1020T/CM. A systematic check of the power, wiring, configuration, and software settings will help ensure smooth and reliable CAN communication.
