Do you have or plan to someday use mechanical rotary style joysticks? Want to build a standalone panel with a ton of
controls? Want to make it hot-swappable?
Or maybe you'd like to add another
40 inputs / rotary joystick capabilities to your
KeyWiz™ , GP-Wiz™ or other encoder installation? Want to do it without it costing a fortune?
Introducing the lightning-fast
GP-Wiz40™ USB controls interface with integrated
Roto-X™ Technology! The GP-Wiz40 includes the most advanced rotary joystick implementation
available. Costly specialized interfaces with limited capabilities are
no longer required to use mechanical rotary joysticks, thanks to
GroovyGameGear's
exclusive Roto-X Technology.
Features:
- Super-Fast USB Gamepad functionality. Reports the status of ALL 40
inputs up to 125 times a second!!! Much faster than USB Keyboard technology.
- No limitation on the number of simultaneous button presses and each input has equal priority.
- Plug and Play HID device. Tested with 98SE, Win2K/XP and Linux. Will most
likely work with other systems that comply with the the HID
specification.
- Completely bus powered.
- Common GROUND wiring method. Only one input wire and a shared ground line to each switch.
- Easy to use Screw-terminal input connections.
- Smaller footprint. 1.55" x 4.6" board fits just about anywhere.
- Includes 6' USB A to B cable, and printed instruction sheet.
Roto-X Specific Features
- Dual, Independent Rotary control support. The Roto-X™ compatible inputs operate as standard button / joystick inputs until activated by the user. This allows for toggle switches and other "normally active" controls to be used on any of the Roto-X™ capable inputs without issue.
- User tunable pulse output. Match the Roto-X pulse timings to the application for best performance. This is a purely optional feature, as the default hardware timings have been meticulously tested with the most common applications to insure compatibility "out of the box".
- Unique Dual-mode Selectabiliy.
Standard CW / CCW and exclusive "8-Way" mode. Finally, games with
"Front Line-type" controls can be played with a standard rotary
joystick!
- Compatible with any rotary switch with pin quantities in multiples of 3 + Ground. (3, 6, 9, 12, etc.)
- Fully Buffered. Each rotary has it's own dedicated 20 action circular buffer.
- Easy to use Software. May be used interactively (as shown below) or silently via the command line. (Click Screenshot to Download)

The following command-line parameters can be used as well (useful
for automatic configuration at startup, as well as "on-the-fly" reconfiguration through a front end application.)
/ON xIndicates an ON time of x
/OFF xIndicates an OFF time of x
/R1 xSets
the function style of Rotary 1 where if x=1 then it functions as a
regular rotary, and if x=2 then it functions in the alternate mode for
games like "Front-Line".
/R2 xSets the function
style of Rotary 2 where if x=1 then it functions as a regular rotary,
and if x=2 then it functions in the alternate mode for games like
"Front-Line".
Note: Excellent
free
3rd party software is available to allow this interface to send
keypresses for use with admin and front-end applications when necessary.
