with 4-way to 8-way powered restrictor switching
Motor-driven restrictor plate switches between 4 and 8 way in less than
USB Control board drives two joysticks
Can also be switched in a standalone setup (no PC) using two buttons or
a toggle switch
Multiple control boards can be used on one PC for 4 or more players
Note: Above pictures show 2 x joystick mounting screws which are not
included. We have separate mounting kits available for wood panels.
- At last! Full mechanical 4-8
way restriction with powered switching.
- Separate control board plugs
into a USB port and controls two joysticks.
- Comprehensive software
support including test utility and a special utility which can be
command-line or GUI driven.
- Integrated into the Ultimarc
DLL which provides API calls to perform switching, for front-end
- No separate power required.
Takes power from USB port
- Hardware mode also allows
switching using two buttons or a toggle switch.
The ServoStik consists of three parts:
This is installed in the same way as any standard arcade stick.
Mounting method depends on panel design, material and thickness.
Our blind-hole mounting kits can be used on wood panels of thickness
5/8 in or greater.
The motor baseplate mounts using two of the same mounting screws as the
base joystick. NOTE; The two screws shown in the pictures above, which
secure the motor baseplate to the joystick are NOT INCLUDED as these
are part of the joystick mounting hardware.
The control board can be mounted to the motor baseplate of
one of the
two sticks using supplied mounting hardware. Wires from each motor need
to be connected to the screw terminals.
One control board drives two motors.
A four-player panel will require two control boards.

It simply has two GUI buttons for switching to 4-way or 8-way.
All detected control boards (and therefore pairs of sticks) are

Until front-end developers add native support for the ServoStik, this
is the way to automate switching. The front-end needs to be configured
to run a command line before starting games eg:
before all 8-way games
before all 4-way games
When resident: F4 switches to 4-way and F8 switches to 8-way.
You could assign I-PAC-connected controls to these keycodes.
Maybe use I-PAC shifted codes.
JoyTray GUI Mode:
Launch JoyTray.exe by itself and it will show an icon in the

ServoStik menu items based on whether you have them attached.
There is an option to run the program at startup.
API Support (for programmers)
The Ultimarc PacDrive DLL incorporates support for the Servostik. It
provides two API calls:
The DLL is part of the PacDrive SDK which can be downloaded here
This special mode is used when there is no PC and you need to switch
the stick using a toggle switch or two buttons.
The control board can be placed into hardware mode using the test
application (see above). Note this change is PERMANENT.
Switching between 4 and 8 way is done using either two buttons or a

Alternatively you can use a toggle switch with the center connection to
ground and the end connections to the green and white wires.
