Rollover Cable – patch cord

This basically the opposite of a straight through pinout but only one end of the cable is opposite.

A Rollover cable is used to connect between a computer and the "Console" port on a Router to allow programming of the Router. To make a rollover cable you arrange wires as per a standard patch lead of either type "A", or "B" with the jack on one end "rolled over". ie you turn the jack upside down and then insert the wires. (NOTE: you only 'flip' one end, not both!) Commercial rollover cables are usually made from flat cable to avoid confusion. If you cannot find flat cable you should use YELLOW cable when making rollover cables.
