The X-Arcade USB cable for the buttons/joys is 5ft long and fairly sensitive, so you may or may not have luck with a standard USB extension cable if its too long (over 6ft) or not of good quality. Instead use an active USB Repeater Extension Cable.
You can also extend the cable when using the PS/2 connection by getting either a longer serial cable, by connecting two of our serial cables together using a DB9F-DB9F Gender Changer, or by using a PS/2 extension cable.
Cables for the Trackball can be extended with a standard USB extension cable.
You can extend the serial cable for use with one of our console X-adapters with either a longer serial cable or by connecting two of our serial cables together using a DB9F-DB9F Gender Changer.
For extending the internal or BYO wires, see 'Extending Wires' on this page: Advanced BYO Kit installation diagram with wiring schematic.
