Picture of Simple RJ45  DB9 Cisco console cable

Hello everyone,

I just bought my first cisco router (2610) and, in order to learn about it I decide to start a blog. The idea its to provide a step-by-step from nothing to something that can be useful in a SOHO environment. The blog still in the very early steps, but it will be the experience of my interaction with my cisco router. here the URL: http://cisco4dummies.blogspot.com

I bought my router online (craigslist) and it came without the console cable. Looking around I found many articles talking about build your own cable but none as simple and easy as I wanted to be. Many articles describe adapter, mini cables, etc, and I was just looking for some straight, simple, easy do understand instructions.

This instructable is my attempt to provide the level of information I was looking for myself.

First we start with the parts:
  • Cat5e cable (mine has 6ft.);
  • 1 RJ45 Connector;
  • 1 DB9 Connector;
  • Crimp tool;
  • Soldering Iron.

Personally I've found these


to be easier and simpler. That way if you need a 1m cable or 10m cable you select the appropriate ethernet cable.

Soldered this cable, thanks very much. But the reception from the device is, and not a command from the keyboard is not received.

Hi, thank you for your message. No its not a typo. you have to connect cables blue and blue-white to pin 5. I found this info online, use to build my cable and everything works fine, so i decide to keep the pinage same. thank you again PC
