DSD TECH SH-U10 USB to RS485 Converter for Modbus

This works perfectly out of the box, if you are a technical. I had to go to device manager and update the drivers manually from disk. I learned on windows 95, so no problem. After that it has been fully compatible with everything RS485. I use ModBus for just about everything . It hooks up to LG XGb plc with zero issues at 115.2Kbps and other modbus equipment. Just plug and go. The rx/tx lights are nice indicator and helps you diagnose if your not getting a response. Construction is decent for a $10 device, and really not complain about. I don’t suggest an extended industrial deployment with this thing. It is more of a hobbyist , R&D device to have in the lab.

Working well so far! Thank you

A+. Work perfectly. Recommend to use. I use this to communicate with my solar inverter thru RS484.

Excellent product

Works as designed and happy with the price. I used this to talk to two Keller LevelRat pressure sensors and an embedded Linux device on an RS485 network. it was my first time setting up an RS485 network, and this made it easy to troubleshoot using Windows tools for RS485 and modbus.

Had to install the driver manually on W7 but that was easy using the utility included. No problems.

Works great

Bought this item to replace my damaged rs485 to usb adapter. Works perfectly right off the box.

Cheep. Easy to use and set up.

⭐⭐⭐⭐⭐ Brilliant little device that works exactly as described! I bought the DSD TECH SH-U10 USB to RS485 Converter for Modbus to communicate with some solar batteries, and it performed perfectly. The drivers installed easily on my Windows laptop without any issues, and the connection to the batteries was instant. It pulled all the data I needed smoothly and reliably, with no dropouts or connection problems. The build quality feels solid, and the cable is a good length — ideal for working in tight spaces. I was really impressed with how stable the communication was, even during longer sessions. For the price, it’s excellent value and a must-have if you’re working with Modbus systems or solar setups. Simple plug-and-play setup, reliable performance, and accurate data transfer — couldn’t ask for more. Highly recommended!

Working fine, just missed USB extension cable, driver you can download easly

Ho acquistato questa usb per connettere le mie batterie lifepo4 al pc tramite cavo rj45, funziona benissimo

Lo compré porque necesitaba urgentemente comunicar con un dispositivo a través de Modbus RTU. Me llegó al día siguiente y cumplió con lo esperado. Pude comunicarme con el dispositivo y ajustarle la configuración.
