    Works without driver on OSX Ventura!
    My main reason for purchasing this unt was I wanted a short cable (not 3’) and had to work in the OSX Ventura. My older Keyspan was great, but they are so slow in creating device drivers, they may never have one for a Ventura; now that kext’s are not supported by third parties

    A Bit of Overkill
    I needed a RS232 adapter that mapped a USB port to Com8.This one did.It works.The LEDs are a nice touch – though not terribly useful.If you can see a millisecond flash during communications, then they are just fluff.Should come with a RS232 for Dummies book.Summary:Worked for me.

    Works as intended
    This converter works as one would expect. The onboard LEDs help in determining communication activity and if both directions are operating, given the application at hand.

    Great little USB COM port, FTDI compliant
    Fast shipping and device works in all aspects. One really great feature is the clear case has an LED for each data line (TXD, RXD etc) If you trouble shooting a "system" it gives great visual clue as to whether a given data line is passing bytes as it should…wish I had this years ago would have save me countless hours

    Worked for PlusDeck 2c Windows 10 64 bit
    I installed the Gearmo 16in. USB 2.0 to RS-232 Serial Converter, went to the Gearmo website, attempted to download the drivers, but was told the latest drivers were already installed. Did the same for the CD that came with the converter and got the same message. No surprise. Typically, website drivers are the latest and greatest, so I would start there first as long as you’ve made sure you have the latest Windows updates.For me, the converter took a little time to be detected, but it was and it works great now. Maybe do a restart before you start to think its not working for you. Honestly, I haven’t relied on the indicators since the installation. Maybe you will if you have an issue. I’m just happy it works as I’ve tried other, cheaper ("less sophisticated") converters with no success. Hope this helps someone who still has a Plusdeck 2c like I do.

    USb to serial adapter
    Best one I’ve found, just wish it came with the Windows 10 drivers. Not a big deal, I downloaded them.
