Review: Does operate as advertised, but setting it up is unnecessarily complex - To set it up to do Modbus to MQTT you need to run software (downloadable easily) and upload settings to the device. The whole process could be made much easier with a better UI (any UI?) on the device itself. More of a problem is that the user guide and the user interface are written in a perplexing approximation of English. Bottom line: it does work, but you will suffer trying to get it set up.
Review: Great item, works good but I can't use it because it was made in China and the software is from China.

### ⭐⭐⭐⭐⭐ Review
*by C***U on 7 March 2023*

Ich benötige den Konverter, um eine Maschine zu überwachen, die entfernt in der Firma steht. Zum Firmennetzwerk besteht eine VPN-Verbindung. Die Software für Einrichtung und den Virtual-Com-Port konnte ich auf der Herstellerseite herunterladen. Die Einrichtung als TCP-Server mit fester IP dauerte 5 Minuten. Auf dem heimischen PC den Virtual-Com-Port-Treiber (VirCom) installiert, in der Maschinensoftware den COM-Port entsprechemd der Einstellung von VirCom geändert und die Verbindung steht. Ich hatte erst Bedenken, da die Maschinensoftware während der Übertragung zwischen verschiedenen Baudraten umschaltet. Aber auch das meistert der Konverter problemlos. Von mir eine klare Kaufempfehlung! Entsprechende technische Kenntnisse sollten jedoch vorhanden sein.
