Troubleshooting CANbus SAE J1939 connection when no data is showing up.
Don’t forget your terminating resistors! Both ends of the CAN bus should be terminated with 120O resistors. Forgetting the resistors can result in signal reflection which will corrupt the data packet and ultimately result in no data. IMPORTANT NOTE: HMI5070P has built-in termination resistor, so a termination resistor is only required for the opposite end… Read More Troubleshooting CANbus SAE J1939 connection when no data is showing up.
