I have an RS485 network: a computer communicates with 16 control boards using a 2-wire rs485 bus. Can I move this to a wireless network with RS485 wireless nodes? What products might there be to help?
@wellems, what range do you need and what world region will this be located?
The short answer is yes; however, really depends on what you are willing to accept and what protocols you wish to use; for example if simply wanting to have a wifi node at each RS-485 board; there is things like Moxa boxes, which have the potential to translate from serial(RS-232/422/485) to …say TCP or UDP, pending if you want message acknowledgments or not.
First things first though, I would check the type of wireless you wish to use … i.e. Bluetooth, 802.11, or what is the distance from each board to the computer? this may help you decide what wireless protocol to review.

It’s actually in a single room in Texas.
@wellems, for a single room in Texas, I was thinking something with more distance between nodes. So how about something simpler…
How many rs-485 connector pairs do you have? For 16 pairs i’m thinking something like:
plus an off the shelf WiFi Router?
Edit: actually copy the part number of the rs-485 variant…
