## Questions & Answers

**Q: What is the pin mapping from the rj45 to db9 pins?**
A: I'm sorry but I don't know what the pin mapping is.  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.
