Review: Connected old machine to Windows 11 - Worked perfectly to connect an old BioTek Synergy HT plate reader to a windows 11 machine (just had to reassign the USB port to be Com1 to work with Gen5 software.) I'm very pleased with this product!
Review: RS232 without headaches or plug in cards! - These are great. I use them to run my ham radio rigs via the PC. They handle the max baud rate of the radio rigs fine, work fine with Windows 11 and have a non-weird chip set - no driver worries! Dead simple to use - true plug and play. The only caveat is that all of my ham radio rigs all have male serial port plugs on them and this adapter has a male plug. This necessitates a straight through gender changer, so I keep some of those on hand, as I've never found these USB to Serial Port adapters with the female plug. Otherwise, these are perfect!!!

### ⭐⭐⭐⭐⭐ IT JUST WORKED !
*by C***J on June 3, 2024*

Keep this short and sweet. My existing USB-A to RS-232 (db9) cable would not work or be recognized under Windows 11. The drivers for the chipsets used in the cable were not updated by the vendor for whatever reason. Maybe to sell new cables, who knows. Time for an upgrade. Purchased this cable and it was plug and play, no problems. I use the cable for programming radio scanners that listen to public safety. This cable was for an older radio that uses a little older programming interface. No problems experienced to date. Have used the cable a couple of times.
