Tool/software:
I need implement a RS232/422/485 compatible design on one DB9 connector.
The pinout is EIA standard.
I found THVD4431 is perfect for RS232 protocol but totally different pinout for RS422/RS485 protocol.
If TI can provide a solution for this kind of requirement?
Hi Wei,
Thanks for posting this question.
The main solution might be to use a mux to switch the signals that output to the DB9 connector. This E2E thread describes it here:
This would allow you to still comply with each EIA pinout standards.
Best,
Ethan
