Tripp Lite P403-006 Cisco Serial Rollover Console Cable will allow you to connect your PC or Laptop to a Cisco device through the console port. This cable is identical to the one that ships with Cisco switches, firewalls, routers, wireless devices including the Aironet 1200. It works with Cisco gear both new and old. If you have a newer PC or laptop, it may not have the 9-pin serial port, in which case you would purchase Tripp Lites USB -Serial adapter, which will connect the two DB9 ends together.
