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.
I've been searching for some time now, but most info I find is in Spanish
Can anyone point me in the correct direction??
Please keep in mind I'm a arduino newbe!
