DTECH 3 Feet USB to Serial Female Adapter Cable DB9 RS232 to USB 2.0 Cord with Prolific PL2303 Chip Windows 11 10 8 7 Mac Linux (9 Pin 2 Row Connector RS232C Protocol)

I purchased these for a project for work. I need them for the connections and found they worked perfectly.

I used it for about 5 minutes.. connected to Chico router.. then I realized ti was not need in my case.. solid product. make sure you need it.

A must have cable for setup on a Cisco router or switch. There are no issues with these cables, connect one to the Cisco equipment and the other into your computer or laptop. You will need the free software "Putty" to use these. You can't go wrong for the money on these as you will need them.

Does what it says on the package: I can communicate between two PCs with this cable and a male DB9 on the other computer. I'm writing a telecommunications program, and I needed to be able to debug the program on my PC and another physical device. I was able to get reliable communication at up to 230Kbps. This is twice as fast as the 115Kbps on PCs with a hardware UART, so I'm satisfied. As others have said, this is wired as a NULL MODEM, or DCE device. For most use cases, this is not the cable you're looking for, and you'd need a DTE connector. This is for connecting two computers together, not connecting a computer and a modem.

Don't know if it is an issue with the cable or the radio. The radio may require the 12volt rs232 signaling and not the 5 volt.

Just what I needed

Did not work with my PoE switch. I got some gender changers and was able to use a different USB-to-serial cable successfully with the same switch. Update: ... but it does work fine with my Davis Vantage Pro 2 weather station. I would guess the peculiarity is because of my Nortel switch's weirdness.

Worked in accordance with how it should work.
