These are awesome. The screws can be removed without them falling apart so I can plug them directly into my cable and into the device I am connecting to. My only complaint is that they came in a 2-pack with the same genders. I don't need 2 of the same thing. 1 of each type would have been more useful to me. Male to male, female to female and male to female in one kit would have been perfect.

I had a new system that needed a null modem cable. I had a conventional RS232 cable of the proper length with nicely molded connectors. Instead of cutting one off and rewiring a new connector to create a null modem, I purchased this DB9 null modem adapter. Perfect! Arrived next day. Took a minute to install and the system took off, as expected. A well made part.

I have some hardware I will need to interface with. Not sure the gender of the DB-9 connectors or if it's a pass-through or NULL modem. These adapters should allow me to get things up and running regardless of the configuration. Seem to be well-made.

If you need one, you know what it does. It works well, and was priced good

I ended up buying these adapters to correct a driver problem on my laptop, it sounds strange but that's how it happened, I read in a forum that someone had the same problem as me, the PC did not recognize the RS232 cable and the solution was to buy this adapter just so corrected the problem.

Pretty straightforward adapter that works. Just ensure that you confirm whether you need “Straight†or “Dull Modem†which reverses the wiring.

Ordered the wrong adapters, my fault, got caught by terminology. I ordered M/F I needed F/F. Sent in another order. I am happy to add to my toolbox, I do a lot of serial device connectivity. Good solid product, for a simple device.
