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.

Step 1: Getting Started - Bill of Material


First we start with the parts:
  • Cat5e cable (mine has 6ft.);
  • 1 RJ45 Connector;
  • 1 DB9 Connector;
  • Crimp tool;
  • Soldering Iron.
<p>Hi </p><p>I also have a point of sale workstation that doesnt have serial port for DB9 so that i can connect an Epson printer, how do i convert a normal fly lead such that one end is RJ45 and the other is DB9 male? Please help</p>
<p>If you need to make one of these and only have male DB9 connectors on hand, as opposed to the female shown above, and a null modem cable then you need to use this pin assignment instead:</p><p>CAT5 -&gt; DB9 Pin<br>Green-White -&gt; 7</p><p>Green -&gt; 4</p><p>Orange-White -&gt; 3</p><p>Blue -&gt; 5</p><p>Blue-White -&gt; 5</p><p>Orange -&gt; 2</p><p>Brown-White -&gt; 1</p><p>Brown -&gt; 8</p><p>You would connect this cable to the null model cable and then connect the null model cable to your computer.</p>
<p>Why on Earth would you use a RJ45 as a serial connector, instead of the standard DB9 ? Another Cisco brilliance at its finest ...</p>
<p>So you can patch it into a patch panel and send it away from the rack. Granted, you could do this with 2x DB9/RJ45 cables but this is neater. Lots of other manufacturers use an RJ45 console port, RAD, LOOP, Verilink.etc</p>
<p>We are the factory for FTDI USB TO RJ45 CONSOLE CABLE ,Our website</p><p><a href="http://www.optimalcable.com.cn/" rel="nofollow">http://www.optimalcable.com.cn/</a></p>
<p>Personally I've found these</p><p><a href="http://www.cablemonkey.co.uk/cat5e-accessories/1485-rj45-socket-to-d9-male-modular-d-adapter.html" rel="nofollow">www.cablemonkey.co.uk/cat5e-accessories/1485-rj45-...</a></p><p>to be easier and simpler. That way if you need a 1m cable or 10m cable you select the appropriate ethernet cable.</p>
<p>I just did it and it works perfectly! Thanks for the instructions.</p>
Soldered this cable, thanks very much. But the reception from the device is, and not a command from the keyboard is not received.
hi Mr.pcapelo, very interesting i'ble as i'm doin my CCNA and a friend of mine was askin me to make a console cable for his 2500 router for practicing. Thanks to you now i can clear my doubts. just 1 doubt regarding step 3 of your i'ble, you have mentioned DB9 pin 5 twice, i'm sure there's a typo there. cud you please clear my doubt??? Once again, GR8 i'ble God Bless
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
