First of all, I hope I placed this question in the correct sub forum...

I'm looking for a way to connect my arduino to a RS485 device (it this case a airconditioner) and read and write information (settings) to the device.

Please keep in mind I'm a arduino newbe! smiley

! Thanks in advance ! ! Thanks in advance ! ! Thanks in advance !

Hi,

Connecting via RS485 is one thing, being able to communicate is quite another. Do you have the software specifications re: the communications bus? They may or may not be easy to discover. If not, I'd stay away from this project as a beginner.
