Review for Pro Grade FTDI USB to RS-232
2015-06-23
Robert B.

I liked this USB to Serial Adapter because it was easy to work with and move out of the way if needed. For its size, it really had almost no weight to it and the physical size was smaller in comparison to a wireless mouse you would use with your computer and obviously thinner. The LED’s were visually bright and noticeable. I would certainly recommend using this adapter particularly when you are using it for a serial application that requires not only RS232 specifications but RS422 or RS485 signals as well.
