I will be using the RS485 Interface and just want to make sure that I'm on the right track (See Attachment)?
I want to make use of 4 twisted pair cables, 2 for the Serial comms between the stations and 2 for the power (don't know if 12volts is too much?)
The Base station (Top) will continually ask each station it's status. When it receives a reply or reach a timeout it will move on to the next one.
The cable length between the stations will be about 20 meter (65ft) and I rather want a reliable connection than a fast one.
Thank you
