Features:

• Uses Tornado-style Spinner Tops, the best available anywhere.
• Two modes of operation:
• Can be used as a lightweight Super High Resolution Low-Inertia Trackwheel control as used in "Arkanoid"
• Can also be used as a spinner with the addition of one of two sizes of fly-weight to provide inertia giving long spin-times of up to 20 seconds.
• Correctly-designed flywheels with mass concentrated at the larger radius.
• Ultra-high resolution.  Unbeatable 1200 pulses per revolution..
• Super-tough quality. Unit is manufactured by a supplier of encoders for high-speed motor usage and is almost identical to their industrial unit.
• Dual sealed ball-bearing races give the ultimate in smooth control.
• One-Piece bearing housing/body CNC machined from a solid alloy billet
• Available in two versions, for direct connection to USB, or for connection to our Opti-PAC or Mini-PAC interfaces.
• In USB mode, this is the worlds only USB 2.0 spinner.  USB 2.0 enables a 16-bit interface and a faster packet-rate than USB 1.1 Vital to avoid slowdown or backspin.
• Usage not limited to gaming! Also suitable for precision control applications, CNC interfacing and other rotary measurement applications.

Optional 6 inch mini steering wheel (160mm)

USB Version. Has 3 Mouse button connections .

Connection to Mini-PAC
The Mini-PAC wiring harness is supplied with an adaptor header. The connection from the harness to the SpinTrak should look like this:


Connection to Opti-PAC
For Opti-PAC connection, the 4-pin connector fitted to the device must be cut off and the wires stripped back. They are connected as follows:

Brown	+5Volts
Yellow	X1
Green	X2
White	GND

Connecting Mouse Buttons
Mouse buttons are connected to 3  pins on the header as shown in the picture below.
The COM connection of both switches should be connected to COM and the normally-open connection of each switch to the LEFT or RIGHT pin.

Flywheel Removal

Note owing to tight tolerances to avoid runout the flywheel might need to be removed by using the knob to hold the shaft and twist off the flywheel (remove both the screws first!).
