USB to Serial RS-232 Adapter with LED Indicators, FTDI Chipset, Supports Windows 11/10/8.1/8/7, Mac OS X 10.6 and Above

Product Review (submitted on April 20, 2023):

I bought this RS-232 adapter to replace a similar device that was based on the Prolific chip. The Prolific seems to be getting increasingly difficult to get working in Windows 10/11 OS. Not sure what's changed but I grew tired enough of it that I decided to give this FTDI-based unit a try. I'm pleased to say that it works perfectly. I use it for programming a variety PLC devices (ATOS solenoid drivers, etc). Another great feature is the line activity lights that show whether or not signal is present on each individual conductor of the RS-232 connector. This, I have found quite useful in troubleshooting and simpler than software-based solutions.
