Works flawlessly for legacy PLCs and HMIs (FTDI Chipset is the key!)
As an Industrial Automation Engineer, finding a reliable USB-C to serial adapter is a constant battle. A lot of the cheaper cables on the market use inferior chipsets that choke when trying to establish a clean handshake with older industrial hardware. This OIKWAN cable uses the genuine FTDI chipset, which is the absolute gold standard for reliability. I bought this specifically to communicate with some legacy Mitsubishi Electric gear that still requires a solid RS232 connection. It worked flawlessly out of the box for transferring both PLC and HMI programs on: Mitsubishi Electric FX2N PLC Mitsubishi Electric F940GOT HMI While I can’t personally guarantee it will work with every single legacy device ever made, the fact that it handled this specific Mitsubishi hardware without a single dropped packet or communication timeout is a massive win. If you work in industrial automation and your newer programming laptop only has USB-C ports, keeping one of these in your tool bag is a no-brainer. Highly recommended!

Driver needed for Mac
Works perfectly to connect a Lokprogrammer to a PC. Mac will require a driver to be installed, and then it works on Mac as well.

Helped with our Pinewood Derby
Use this to connect a Pinewood Derby timing gate (FastTrack) to a MacBook. Has been working well and provided no issues for me. Length was good, and didn't have any issues with Grand Prix Race Manager software connecting to it. It replaced a series of connectors to convert serial to USB-A.

Cannot connect on MACBook Pro Intel Processor
This RS232 to USB C cable arrived today and does not connect or work with my MACBook Pro running Sonoma. I went to the website and it only includes information for Windows even though it says it will run on a MAC. I have tried looking in the AppStore for drivers and found nothing for FTDI. Their site has drives but there is no mention of anything for a MAC. This is totally not what is advertised and doesn't function as a data cable for my needs of connecting it to an INNOVA ScanTool CanODB2.

Works on Windows 11
Works well, works on Windows 11 which is very important. I used it to run an old score board when the previous adapter I had suddenly stopped working after upgrading the laptop to Windows 11.

Nécessite un pilote et ne fonctionne pas sous Windows 11
La description de ce produit est plutôt mensongère. Présenté comme fonctionnant sans pilote, il faut pourtant en installer un. Sur le site du fabriquant, les pilotes sont anciens et ne fonctionnent pas avec les versions récentes de Windows 11. Ne fonctionne pas non plus avec Windows 10 sous Virtual Box ni Windows 11 sous Parallels Desktop.

Works with Windows 10 Pro
Worked great with an older HP EliteBook 820 running Windows 10 Pro to update an aviation Garmin portable GPS196. Appears to also install ok after connecting to my MacBook with an M1 processor

Works perfectly on a Mac running Windows 11 virtual machine.
Used these on a Mac running a Virtual Windows 11 machine (Arm version). They work perfectly. No need to add extra drivers.
