6-Pack 9Pin RS232 Serial Cable DB9 Male to Male/Female to Female Mini Gender Changer Adapter Coupler Connector

Very well built, and small form factor. Fits nicely into a cable run, or directly attached to a port on a machine. The captive screws hold everything together, and make modifying easy. Good value for the few dollars, for sure. It's a full pass-through, so it has all of the functionality you could ever need, and it's compatible with all ports because of that.

They’re 232’s. They work well and are easy to use.

These did the job I was expected. They seem well made an just plain work

These work fine and matched the description (3 each F-F and M-M). There are nuts on both sides of the F-F connectors, which may prevent insertion into a M connector with female threads, such as a 34401 multimeter. Removing the nuts from the adapter allows it to work with the bolts it comes with, but they hold it together and it's fiddly to re-assemble if it is pulled apart. Having it apart it was clear that all the pins are wired straight through. Removing the nuts will also remove the shield to shield ground connection. A few dabs of epoxy is recommended to hold it together if you need to remove these nuts.

Very good!!

They turn male to female and female to male.

Good to have if you're working with older monitor connections, or want you made a few adjustments with old VGA monitors, etc.
