I am trying to devise a solution for a home with an existing RadioRA 2 system and a driveway gate. The driveway gate suffered a lightning surge which fried the existing z-wave controller that controlled the landscape lights around the gate and allowed operation of the gate from a mobile app.
I would like to tie the gate lighting and mobile gate control into the existing RadioRA 2 system by installing an auxiliary repeater and visor controller at the gate...the main obstacle is distance.
I need a way to connect the RS485 link to the new aux. repeater. There is existing multimode fiber going to the gate control box, and I am aware of the serial to fiber modem solution that Lutron recommends, however there is only one fiber pair and I cannot repurpose it solely for RS485 since it is also used for IP communication to a camera and the access control box.
Does anyone have experience tunneling RS485 serial connections over IP? I've been experimenting with a pair of serial ethernet modems (specifically these https://gridconnect.com/usb-to-seria...net-cable.html) but have had no luck so far getting the RS485 signal to successfully cross the network.
Below is an illustration of what I am trying to do...the existing infrastructure is orange, and the proposed new solution is blue.
Any advice on this is greatly appreciated!
