Review: Works just fine - Using it for 422, no problems, only gave it 4 stars since the driver install did not go perfectly the first time. It seems to be a bit over priced for a USB serial converter. Bought another one after 5 years, someone has walked off with the one I had originally. When other RS422 adapters fail to work, this one works. No driver needed on Windows 7.
Review: Received 2 1US & 1 CA - Received 2 1US & 1 CA 1 sets on shelf as backup.

### ⭐ NOT RS485 2 wire compliant
*by T***R on August 1, 2013*

I will keep this for the next time I may need RS422. But it seems all FTDI FT232RL Chipset converters have missed the boat on RS485 2 wire communication. RS485 can be 2 wire or 4 wire (RS422). The ground is optional in both cases. There is no voltage or signal between D- and D+. There is a voltage difference to ground, but that is completely useless with 2 wires.
