I initially tried making my own cable, but it wouldn’t work, so I decided to buy this one—and I’m glad I did! It worked immediately to reset the password on my PDU with no issues at all. The cable length is excellent, giving me plenty of room to work. Being FTDI-based, the drivers installed and worked flawlessly without any hassle. This is a reliable and well-made adapter that saved me a ton of time and frustration. Highly recommend it for anyone needing a dependable APC USB to RJ11/12 solution!

This serial cable worked perfectly for my APC AP8941 PDU. It was plug and play. No drivers, just open putty, select serial and enter the COM port and I was in. Too easy and highly recommended!

I remember back in the day, if you needed a specialized cable to help interface with a networking device that you had to build one from scratch and it was using a RS232 pinout to connect you cable and use that interface. Now, you have the interface end and USB. All you have to do is plug it in, install the driver, and go. No more having to make cables. This cable came in clutch when needing to configure a certain electronic device to be able to configure it. So if you are looking for this type of cable don't worry it will work... just install the drivers and go.
