## Customer Reviews

### ⭐⭐⭐⭐⭐ Great item
*by V***R on November 17, 2024*

Great item, works good but I can't use it because it was made in China and the software is from China.

### ⭐⭐⭐⭐ Review

fácil de configurar, manuales disponibles en Internet

### ⭐ It might work, but the instructions are completely opaque, and ridiculously complex.
*by K***S on December 8, 2024*

I needed a Modbus RTU to Modbus TCP converter to go between a small network of PLCs, power meters, and genset controllers. Never could make sense of the instructions: specifically the application program(s) being in Chinese and the specific example for RTU to TCP just plain old didn't work, even after hours of messing with it. I've used a ton of other Waveshare products without any issues at all, but based on my experience and the experience of another user I know in meat-space, anything Waveshare with "to ethernet" in the product description is too difficult to work with when evaluated in terms of my time. YMMV, but I'll stick with other more expensive but *easily* functional solutions.
