Dear Support,
I have a verdin development board with imx8mp, now I need to connect an IMU following rs422 protocol and read data via serial port. How do I wire it up, do I need a converter or other tools?
Best regards,
Hkhkl497
RS422 devices are not electrically compatible with RS232 or TTL UART levels. However, a Verdin development board has an RS485 converter on UART1 that is electrically compatible with RS422. It only supports half-duplex mode, so if your IMU supports half duplex mode, you can use the onboard converter. Otherwise, you would need to use an external RS232 to RS422 converter or RS422 to USB converter.
