Bonjour,
Dans le cadre d’un projet, on utilise le port Ve-direct du mon convertisseur Victron energy 150/60 pour communiquer avec un automate via RS232, pour cela on utilise le câble Interface VE.Direct-à-RS232. Pouvez-vous nous envoyer le schéma de cablage interne de ce adaptateur ?
It's unlikely that there is a circuit diagram for such a thing in the public domain.
I imagine it's pretty basic though. Imagine a MAX232 to do the RS232 - TTL conversion and then a digital isolator for the TTL side (maybe Si8422 or something like that).
Consult the datasheets for those translator and isolator devices and then it will be easy to figure out a functional circuit diagram for your own use.
in this case , we use this cable ( see below ) and we need the internal connection of this interface
