Rolled (Roll-Over) Wiring
Rolled (roll-over) patch cords are not used for network connectivity. These patch cords serve a unique purpose,
and are used to connect the serial port or modem on a PC to the console port of a Cisco^ router or switch.
Rollover patch cords are often referred to as Cisco console cables because they facilitate the configuration of a
Cisco network router or switch from a PC. An RJ45 to DB9 or RJ45 to DB-25 adapter will be needed to connect
the cord to the PC serial port or modem.
As shown in the illustration below, a roll-over patch cord completely reverses the pin configurations between the
two modular plugs. Pin 1 on modular plug end 1 connects to pin 8 on modular plug end 2. Pin 2 on modular plug
end 1 connects to pin 7 on modular plug end 2, and so on.
