RS485 does not specify the protocol used. Connecting an RS-485 buffer
such as a MAX485 or similar is not a problem. (Keeping things such as
stubb lengths etc. in mind). If the protocol used is asynchronous
serial, then adding an RS-232 buffer such as a MAX232, and then
connecting this to a standard PC serial port is all that is needed.
Plus software of course.
