SABRENT USB 2.0 to Serial (9 Pin) DB 9 RS 232 Converter Cable, Prolific Chipset, HEXNUTS, [Windows 11/10/8.1/8/7/VISTA/XP, Mac OS X 10.6 and Above] 2.5 Feet (CB-DB9P)

It worked fine, but "it" selected the virtual COMM PORT. It wouldn't allow me to choose what port I wanted it to be.

Exactly what I expected.

Works every time properly. Smooth connections to the computers

It is easy to get your DB9 pins wrong like I did when at first I thought the Sabrent USB to Serial Model: CB-DB9P did not work. However, it works as advertised. Secondly, check the Windows "Device Manager" under "Ports" to be sure the device driver is present. The Sabrent is NOT plug-n-play. You must download and install the driver which will show up as as a "COM" number in the Windows "Device Manager" under "Ports" which you must correctly select and use with your Terminal Emulator such as PuTTY. Only 4 Stars because plug-n-play would be better.

I bought one of these 3.5 years ago to work with PLCs, that one that I purchased still works. I bought one more recently and it wouldn't work. I bought another one 2 weeks ago and it also would not work. Both I tried with the same computer and compared it to the still working cable, but neither of the new cables would work.Update: The cables are working fine but the software I was working with was a bit troublesome. I overcame the issue and both cables seem to be working well now.

Item as described. Fast shipping

I plugged this device into my MacBook Pro expecting to see devices appear under /dev/cu* and /dev/tty* but nothing appeared. It *does* appear in System Information under the USB subsection, but no devices appear under /dev. Fine, I'll download and install a driver, because this is the year 2025 and apparently drivers are still required for goofy devices like this one. There is no download matching the device I have, so I take a guess at which driver to download. There are three versions of the driver packed inside the .zip so I try the newest one, from 2021. I get a message that the kernel extension needs to be updated and could not be installed. Why in the heck is a usb to serial adapter so difficult in 2025? I would recommend against purchasing anything from Sabrent for a Mac. They clearly don't care about Macs.

The screws around the port are NOT removable. You can't just screw them out. This is important when you are plugging up to a device which also had the same protruding screws and the two butt up against one another preventing the connector from actually working. I'm having to deal with his right now.Not a plug and play solution in every case and short of cutting those mounts off you're going to have to adapt your other parts to work with this.
