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. ## Frequently Bought Together - DSD TECH SH-U11H Isolated USB to RS485 RS422 Adapter for Industry - Industrial USB to RS485 Converter Adapter with Original CH343G and SP485EEN, Built-in Lightningproof Tube, Resettable Fuse, ESD and TVS Protection Circuits, up to 1.2km RS485 Transmission Distance - Hailege RS485 SHT20 Temperature Humidity Sensor Module High Precision Temperature Humidity Monitor Transmitter Sensor Probe Compatible to Modbus with 1M Lead --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/488487603-dsd-tech-sh-u11h-isolated-usb-to-rs485-rs422-adapter](https://www.desertcart.it/products/488487603-dsd-tech-sh-u11h-isolated-usb-to-rs485-rs422-adapter) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
