RS232/485 to a APM2.6


I am new to this and have been searching alot to try find an answer to my question, but have had no luck.
Therefore I am hoping someone here can help or point me in a right dircetion towards my problem.

My problem is :
I have been assinged a project to try modify an sensor solution on a drone using APM 2.6.
The sensor can either send data via RS232 or RS485.
So therefore I wonder if it possible to connect a RS232 or RS485 to the APM 2.6 and send the data throught the telemety link back to the controlstation?

Best Regards
