Going wireless with rs-485

Hello peoples
Wanted to ask someone in the know, is it possible to take any (my air conditioning controller for example) rs-485 signal, cut the wires, install some sort of transmitter/reciever and transfer across a computer network? Or maybe go wireless? Like to know if anyone has had experience.


Thanks.

    Bob,

    ·· What's on either side of the RS-485 signals?· If it's just serial data you have plenty of RF solutions available.· You can find many on our website.·

    You can do it.

    You need two RS-485 to Wireless transcievers [noparse][[/noparse]Rx and Tx].

    You can either figure out how to build them yourself or go to someone like B&B electronics to buy them.

    The wires that you cut are still RS-485 transmit and receive - so they have to interface with a RS-485 device to properly terminate and then convert the information to RF digital.
