## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect product!
*by R***S on March 1, 2022*

I love this converter! I work in a survey industry running cat 5/6 everywhere to to send DB-9 data to a central hub. These are sturdy and work great. I love that one pack comes with a male and a female DB-9 end. The flexible whip is great for tight spaces with lots of cables. I have now bought multiple packs of these after buying one as they are perfect for my job! I have recommended them to my boss for full company use and would absolutely recommend them to anyone looking for the perfect solution for DB-9 to RJ-45 connectors!

### ⭐⭐⭐⭐⭐ Works as intended with "SEL digital relays"
*by T***M on April 13, 2025*

As a utility relay tester, I often test digital protective relays "Sweitzer's or SELs" in the field, on utility poles out in the middle of nowhere. Using a simple network cable about 10 meters, this adapter set, and the SEL cable, it allows me to stay out of the rain and remote test, interrogate and program from my vehicle if I'm in inclement weather. Not getting my test set and my laptop wet. It's well worth the money. It makes my job easier; I'm less likely to get sick in the weather, damage the test set and/or the laptop. I highly recommend it to any technician or engineer who has to interrogate a digital apparatus with an RS232 9 pin serial com port. I don't see any issue with speed, error check, or performance through the front com port at 9600, 19.2 or even higher. The wiring internally maybe proprietary but I continuity checked it before hooking it into the first comm port and there were no issues, pin for pin straight through and invisible to the apparatus and to the Windows USB port. Works as intended.

### ⭐⭐⭐⭐⭐ Works PERFECTLY as an Ethernet pass-through, 1 Gbps to boot!
*by M***T on May 30, 2019*

I needed a way to pass Ethernet through a DB9 "pass through" on a shielded test enclosure. This works perfectly and maintains the integrity of the shielded test enclosure (the built-in pass through does that of course, but I wanted to confirm that it did work and it does).I also tested the speed of the connection using a laptop running Windows 10 with a gigabit Ethernet interface and while connected using these two dongles it showed up as a 1 Gbps connection, sweet!
