It is usually best to simply use the USB connection for laptops. It
is also important to make sure NUMLOCK is ON (otherwise Joy1 will act
as arrow keys instead of NUMPAD numbers). To turn NumLock on with a
laptop, usually you will find a blue colored "Fn" key that must be held while pressing another key labeled "Num Lk". Refer to your laptop's manual for more help with this.
The X-Arcade™ will not work in the PS/2 keyboard port unless a keyboard
is plugged into the back of the X-Arcade™. You need to boot the laptop
up with the X-Arcade™ already plugged in and set to MODE 1 (switch on
back closest to the serial connection), and with a PS/2 keyboard
plugged into the back of the X-Arcade™.
If you have a PS/2 only X-Arcade™ you may simply need our USB X-Adapter™. NOTE: The only USB adapter that will work properly with the X-Arcade™ is the one that was made for it, a standard PS/2-USB will not work
