Because they come as a matched pair of adaptors it didn't matter to me. I used one at each end of a standard 25 foot Cat5e patch cable to make a long DB9-Male to DB9-Female cable and it has been working with no problems for over 6 months. I have previously used other similar adaptors and as you probably suspect there is no standardization. That is why this matched set was appealing. **Q: Where is this made? Thank you.** A: Made in China **Q: will this cable convert the signal, so that it can be seen on a computer monitor ?** A: The RJ45 to RS232 cable is not for video. A DSub15 is the standard connector for VGA video. RS232 is a serial data standard. **Q: Will this work with any usb-rj45 cable with your adapter? so far i cannot get it to work. my cable usb-rj45 works fine, but this doesn't. any ideas** A: Your question does not make any sense in this context. You say your "cable USB-RJ45 works fine" but you asked this about an RJ45 to RS-232 adaptor. Why would you even expect it to work? RS-232 and USB have nothing in common. ## Customer Reviews ### ⭐ ne fonctionne pas *by A***R on 28 July 2025* dans description, ca dit de lire le pinout mais vous la fournissez pas. ### ⭐⭐⭐⭐⭐ Seriell Adapter *by L***F on 16 April 2025* Funktioniert einwandfrei.
