We have some I/O´s on an RS485 network and would like to get access remotely from cellular and/or PC. I am new to IoT, but out from pamphlets, we got the impression that RMS + TRB255 could do the trick in an easy way, and without any static IP. But once bought, it turned out not to be "plug and play", seems to be far more complicated than we thought.
Is it possible to read and control the I/O s via a mobile cellular connection with RMS + TRB, an if yes, how do I get the things up going and speak with each other?
