There have been a few web pages that describe the two ports on the Octo 4-S Varios Controllers located above the float switch connector as two ethernet connectors (in and out) for a future controller.
Coincidentally, those two connectors are GX12 4pin connectors that are identical to sensor input connectors on the Hydros.
I can tell that all 4 pins on the GX12 connectors of the Varios controllers are connected by using an Ohm meter. So they are indeed the same not different signals (I think).
I'm guessing (hoping) that the connector is actually for an alternative optical level sensor input instead of the float sensor. And that the intent was to provide an optical level sensor input to the pump controller that could also be connected to the hydros via the second connector. (Did that make sense?). That would allow both the pump controller to be shut down and the hydros to be notified that the level sensor closed.
That would be very cool if that were the case.... Does anyone here know anything else about the extra connectors on the pump controller.
I realize that you can use the hydros wave to achieve that -- and you can also achieve that using a sensor input on the hydros to shut down a 0-10V signal going to the varios controller.
Nonetheless, wiring the sensor through the pump controller would provide an additional level of security in shutting things down when a level switch closed. I should probably draw a wiring diagram to better explain that....
