    想定していた結果を得られなかった
  
  

*by 関***史 on Reviewed in Japan on 21 May 2024*

DSDの別の製品で良かったため、絶縁型を購入してみたのですが、結果は思わしくなかった。受信は上手くいくのですが、送信が上手くいかない。ということで、お蔵入りとなりそうです。

### ⭐⭐⭐⭐⭐ 







  
    Erste Wahl wenn es um einen guten RS422 Konverter braucht.
  
  

*by B***O on Reviewed in Germany on 30 April 2023*

Ich habe viele RS422 Konverter ausprobiert, dieser hier war mit Abstand der beste:- Aktuelle Treiber (2.2023) für den Chip PL2303GC direkt von Prolific auch für Win11 erhältlich- Onbord 120ohm Widerstände im Bedarfsfall- 5V Spannungsversorgung für das Endgerät. Danach habe ich eine gefühlte Ewigkeit gesucht- bis zu 2Mbaut. Für >1Mbaut habe ich die Widerstände benötigt (werden durch Jumper eingebunden - diese liegen nicht bei)- Status LEDs- Support: Ich habe 2 Konverter für die Einbindung von 2 Sensoren (Xsens MTi-G-710) benötigt. Eines der beiliegenden USB Kabel hatte einen Schaden, für das mir nach kurzer Rückfrage Ersatz angeboten wurde. VorbildlichConclusio: Uneingeschränkt empfehlenswert. Mein einziger Wunsch wären zwei beigelegte Jumper, damit man diese im Bedarfsfall gleich griffbereit hat. Dennoch 5 von 5 SternenTipp: Bei Verbindungsproblemen mit dem Endgeräts im Bedarfsfall RX / TX ( + zu +, - zu - ) zu tauschen. Hat bei mir Wunder gewirkt.
