GNX SEM (Side Extension Module)

A USB connection is not included by default because GNX modules are specifically designed to be connected to Gladiator NXT/EVO joysticks, allowing them to function together as a single integrated device through their internal BUS interface.

If you want to use a GNX module on its own, directly connected to your PC, you'll need to separately purchase and install a GNX USB Controller (HID-Main) to replace the module's default GNX BUS Interface.
