### ⭐⭐⭐⭐⭐ Connected old machine to Windows 11
*by D***E on June 11, 2025*

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!

### ⭐⭐⭐⭐⭐ Serial cable USB
*by T***J on April 3, 2025*

Provides for serial console connection 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.
