The Tripp Lite P430-006 Cisco Serial Rollover Console Cable enables connection of a PC or laptop to a Cisco device through the console port. This cable is a direct replacement for the cable shipped with Cisco switches, firewalls, routers, and wireless devices. It's ideal for connecting to both new and older Cisco equipment. For newer computers lacking a DB9 serial port, a Tripp Lite USB-to-Serial adapter can be used to bridge the connection.
