Interfacing with serial commons on the Vedirect port of a bluesolar charger 75/10
Would use the - rail on the VE connector, but the device communcating with the Vedirect port is getting its power from the Load output as well.
I assume can't connect the the two - rails to get a common negative rail as you're probably using the negative rails to measure current output.
Hence any issues with using the - rail on the load output and communicating via the TX/RX with TTL signal levels and not using - rail on the VEdirect port?
TIA,
Rob.
