StarTechcom 6ft (1.8m) 1-Port FTDI USB to Serial RS232 Adapter Cable with COM Retention, USB to RS232 Adapter - TAA

I am using it to connect my serial port weather station to a Mac Mini. It works natively on my Mac, no drivers to download or install because it uses the FTDI chipset that is supported on Mac OS Sonoma. Hoping it continues to work on Mac OS Sequoia when it is released, but haven't been able to test that yet.

I've been buying products from StarTech for a very long time. Their products are are always high quality and their technical support is excellent, with current manuals and drivers always available online. The USB to Serial Adapter uses industry standard FTDI chipsets and remembers the last serial port number assigned to the device which eliminates searching device manager for determining the port number or resetting the port number.

Initially purchased the Gearhead USB to serial converter from a local computer store, to use with my new Dell Inspiron 3000 PC running Windows 8.1. Big mistake! Should have checked reviews in Amazon first. The Gearhead unit came with a driver disk, and on the box it said it was Windows 8 compatible. Wrong. Driver loaded with a Windows alarm in Device Manager, about insufficient virtual memory. Anyway, could not make it work. Returned to store. Ordered the StarTech adaptor from Amazon, recommended by Amazon users, and known to work with Windows 8. Sure enough, when it arrived, plugged the USB end into my Dell and Windows discovered the driver automatically via Windows Update. Did not even need to load the driver from disk.. Worked perfectly, with my Dylos Laser Particle Counter, which only has a serial port. Now plotting particle counts on PC. Six foot cable with Startech adaptor is 6 feet long; important when monitoring counts in real time from the fairly large particle counter, and must set the laptop down somewhere nearby.

This works great used it in tandem with the SF Cable, DB9 Female to 3.5mm Serial Cable, to connect to my Smart TV in order to do video calibrations. Does what it should buy with confidence.

With the MacOS update to Big Sur, my go-to USB-to-Serial adapter, Keyspan by TripLite, stopped working. Big Sur requires signed drivers and there isn’t one for the Prolific UART chip in the Keyspan. The StarTech uses the FTDI chip and it just worked right out of the box.No need to install a driver, just add a USB to USB-C adapter to plug it in and things just work.

We had an older serial to USB cable that my wife used to connect her court reporting machine to her laptop. When we upgraded to Windows 10, It stopped working consistently. After a great deal of research, we discovered that the chipset in the original cable was no longer supported. This new cable was easy to set up and appears to be working flawlessly.

My newer computer does not have a serial port which is needed for my older weather station. The StarTech USB to serial adapter was easy to setup. Let windows 10 find the driver. It works better than when it was connected to the serial port on my old computer. I tried another brand adapter that didn't work well with my weather station. It would show up then disappear. StarTech works.

The unit works ok but did not have attachment screws to hold it on the jack. Have to use a rubber band to keep it on!
