Help me source this connector, please. Its a 4 terminal removable block on Hayward VSP and Jandy. I have googled high and dry without finding it and am loathe to wire up using maybe crimp connectors with the high voltage around.
Have you tried Hayward? Jandy? FWIW, my Pentair Intelliconnect box uses an RS485 cable to connect the Pentair Intelliflow VSF pump. It only uses the green and yellow wires. I know...not much help. However that does suggest that there may be multiple uses of RS485 serial connections and the equipment manufacturer is the best bet. I've gotten a lot of information from Pentair tech support--and that's especially good, since my pool builder didn't even know the Intelliflow pump could be connected to the Intelliconnect box, even though the RS485 cable was shipped with the pump.
