What is the RS-485 port for on a Gen 3 Wall Connector?

Just got my Wall Connector installed (finally!). Reading the manual in detail now that I've got it up & running....

I see on p. 10 of the manual that I've got an RS-485 port inside. I gather from reading here that the Gen 2 connectors used it for load sharing? (Which function is allegedly "coming soon" via firmware update on Gen 3?)

Is the port active on the Gen 3? What does it do?

The "load sharing" software for the Gen 3 has not been released yet, so there is no way to know what if anything it will be used for. The Gen 3 load sharing is intended to be via WIFI, however it is plausible that they will allow a wired option as well.

The Gen2 did not. They used a terminal strip for load sharing. Not sure where you saw a 485 port on a Gen2. :D

The port on the Gen3 may be for firmware loading/testing at the factory or some such.

Like I said earlier, the Gen 3 software is a work-in-progress and therefore it is available to the software developers if they want to use it.

They can literally do anything with it or nothing.

That little connector serves NO purpose.
For the moment, the components (U12?) for that RS-485 interface are not populated ...
See this THREAD for more info & photos.
