Ducato converters socket D+ and Victron B2B

[yorkiebar]

Has anyone wired up a Victron B2B to use the D+ signal from the converters socket on a Ducato/Boxer ?
If I understand correctly then the D+ signal from the converters socket is actually pulled down to -ve when the alternator is running (open circuit otherwise).
And if so, then wiring this "D+" signal to the "L" remote terminal of the Victron B2B should trigger the B2B when the alternator is active.

Can anyone verify this ?

Many thanks.

Never seen a D+ signal going to ground easy enough to check with a volt meter.

It's in the Fiat converters manual and confirmed elsewhere.

Perhaps a lot ofthe manufacturers convert, I've had 3 Hymers the d+ went positive but they did have relay boxes controlling it, current Carthago has a simulated D+ it's common on vans with CBE distribution systems.

As I said it's easy to check.

I will check but I've no reason to doubt the documentation + other websites which have confirmed it.

Just looking to see if others have used the "L" terminal of the remote block on the Victron B2B with the converters block "D+"
