Adaptateur USB série de très bonne qualité on peut facilement brancher les fils et avoir une connexion USB sur PC qui est immédiatement reconnu sur Windows et Linux je l'utilise dans le travail pour des projets informatiques et ça évite d'avoir trois adaptateurs différents pour chacun des protocoles série il suffit de refaire le branchement en utilisant simplement un tournevis et le tour est joué pour pouvoir envoyer les commandes par l'interface USB Je recommende
