Review on 🔌 DTECH USB to RS422 RS485 Serial Port Adapter Cable with FTDI Chipset: Effortless Connectivity for Windows 10/8/7/XP Mac (4 Feet) by Matthew Goyette

Not working. I just spent 10 hours trying to find an error reading data from a controller with this device. I resorted to setting up the oscilloscope and directly observed the data coming from the controller. This is fully compliant with RS-485 specifications, but this device does not show "flicker" in the received data. I give him low stars because his support is next to impossible. The manual I found was in a combination of Chinese and English in a barely understandable Word document. I declined and ordered another device from a different manufacturer and this one is going in the bin. I see the reviews are mixed. Either it works for some and for some it doesn't. This suggests that the build quality is abysmal. Anyone attempting to implement RS-485 is most likely a reasonably experienced technician and not a regular home consumer. Such a device should just work.
