NOT a crossover cable that reverses TX and RX to connect two computers or two switches.

If you are unsure of the assigned COM port:
1)
Connect the cable to a USB port

Connecting with a long USB extension cable may cause the console functions to operate incorrectly. A
maximum length of 15 feet is recommended.

Older FTDI or Prolific drivers may need to be uninstalled in order to install the latest FTDI drivers.
Uninstall the drivers, plug-in the cable, and reinstall the drivers. Consult the FTDI Driver Installation
