Oh okay. Thank you.
Without the diodes, how would the circuit look like? Would I still need to tie the Tx pin to 5V at the controller side?
Is there a sample program which I can use? I am currently using a program which only accepts serial commands(https://github.com/JetsonHacksNano/UARTDemo)

Hello,
Also is the diodes and resistor setup necessary if I am using RS232 to 3.3V TTL adapter for conversion?

Thank you for the prompt response. I did set it to inverted serial logic and I’m able to measure logic high around 3V at the end of the convertor. What is the best way to check communication from the motor controller with the NVIDIA? Can I request a query like controller voltage so I get a response?

Hello,
I am having trouble establishing serial communication from NVIDIA microcontroller(Jetson nano) and the Roboteq motor controller(FBL2360T)
The idea is to communicate motor commands from the Jetson.
RS232 logic level from motor controller: +/- 10V
Using an RS232 to TTL convertor, I am able to convert it to 3.3V logic level.…[Read more] -
