Do a search on cisco and "console cable" to get the right pinouts.

I did a quick search using the terms [ "serial port" RJ45 "pin out" ] on
Google. Try this for a description:
    http://www.arcelect.com/rs232.htm

Drawback is that it may not be a standard. I went back to search a bit
more using ["serial port" RJ45 "pin out" cisco] and found this

http://www.cisco.com/en/US/products/hw/video/ps1870/products_administration_
guide_chapter09186a008007d503.html
and

http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=pincabser_cisco_9

These show different pinouts than the previous link. I would keep
searching til you have a better feeling of the results. Final task would
probably be pick one pinout and test until you find a match. You can
also watch pins from the RJ45 unit and watch for data being transmitted
using an AC volt meter. Be sure to identify the ground pin before
starting. This could give you a starting point.
