Hi
I would like to connect an RIO in an outbuilding to my comfort system in the main house. Although I have a multicore cable running between the two buildings (which I could use for the +/- connections) I do not have a CAT5 or other twisted pair connection and it would be very difficult to install one. Can anyone advise me on whether I can install a wireless bridge of some sort to carry RS485 between the two buildings? I am based in the UK.
Thanks
Graham

If the outbuilding is not very far it may be worthwhile to try the RIO through the existing cable even though it is not CAT5. I dont know of any easy RS485 over wireless solutions

Thanks for the suggestion; I can try that. Since my previous post I have realised/remembered that I do have one Cat5 cable running between the house and outbuilding, but it is being used as an ethernet connection. I think therefore it only uses two of the twisted pairs in the cable. Could I use one of the other twisted pairs for the RS485 signal or would it cause a problem running the RS485 signal and ethernet signal through the same cable? Again, many thanks for your help/advice.

You should be able to run the Comfort Bus (4 wires) and the network signals in the same CAT 5 cable provided you make sure that you use the correct wires, and make sure you pair the 12V/COM and KA/KB together

Brilliant!
Thanks for the advice. I will try exactly that.
