the product works fine. I added my device to the rs485 bus and without installing drivers, was able to read data from /dev/ttyUSB0All is good, but look at the product specs.. it does not follow the RS485 convention of A- and B+The labels are only A and B but in this case + is connected to A.I saw this in another review before I connected this to my 485 bus, but I'm adding this review to make sure it gets seen by others too.

We need these to connect programmers to our Pheonix lighting controllers. They work incredibly well for that purpose.

I've tried several of these. About 50% dead on arrival. More failed after a short time. Look for another option.

Underwhelmed with backwards terminal labels. Convention is that A is (-). Not on this device.Also changing port address seemed to require unplugging/re-plugging in converter. This could be a Windows issue but I'm not convinced. I'm usually a 5-star reviewer. This is functional but "meh".

This adapter actually works. I have a half-duplex RS485 sensor and it works with 5V so the 5V connection on the adapter is really convenient. I've bought a few other half-duplex RS485 USB adapters that didn't work. Simply designed wrong. I mean, how hard can this be? A couple of ICs and a few resistors and caps. So this product may have been designed by someone who is competent.

I got this to add digital control for speed on a HuanYang VFD controller and Mach 3, it was easy peasy! Works well without a hiccup!

I needed to connect my Renogy Rover Elite 20W solar charge controller to my Raspberry Pi 4 to monitor its stats and I needed to communicate via the RS485 port on the controller. Took a bit of research to figure things out but worked in the end!
