In Serial Cables

Worked without issue on both Windows 10 via Putty and macOS via screen.

Unlike other brands of USB to Serial converters we have used, the Startech model performs without a hitch. Other converters tend to drop communications or hang momentarily when the connected device sends a large streams of data. Not the Startech. It handled everything thrown its way.

Configured my dell switch with no issues.

- works without any setup on linux

This really is a 1 meter long F/F null modem cable; it appears to be well-made. I used a continuity tester on it and found that all nine pins are cross-connected appropriately.

works as expected, no issues

- Open box - Load driver - Plugin and go

I stick data in one end and it comes out looking the same on the other end. These work fine

If you are in the vinyl sign business, or own a vinyl plotter / cutter, and want to cut from your Mac, you have to have this. Not any USB to Serial hub will do. Nearly every plotter software support company will tell you brand specific that it really needs to be the KeySpan adapter. (if you want to cut from Mac) I've used cheaper ones, and they don't always work properly, if at all.

I love it so much!

Brings serial ports on my ASRock X99 WS out to the rear panel, where I have one hooked up to my Cyber Power UPS for monitoring purposes. Ribbon cables are more than long enough for the job and need to be dressed after installation. Price is perfect.
