USB to RS-232 Serial Adapter w/ LED Indicators Windows 11 Support

Product Review (submitted on June 13, 2023):
I needed this to help program and diagnose a fire alarm panel. I initially wired my connector incorrectly and could not get any communication. Thanks to the lights on this adapter I was able to quickly diagnose my mistake and get my programming done. I had originally used a more expensive adapter from a local store but couldn't get any communication and thought it was defective (which I later learned was my mistake). If you need a USB to serial, this is the only way to go!
