Spinner Control - Hagstrom KE-USB108 User Manual

The purpose of the header is to accommodate varying Trackball
hardware configurations. Some Trackballs require the interface
lines to be pulled up to +5V, while others require the interface
lines to be pulled down to logic ground.
Trackball Jumper Settings:
* Pull-Ups - Trackballs that require outputs to be pulled up to +5V
may be accommodated by placing the jumper on to the center pin
and the pin to the right of the header (active low).
* Pull-downs - Trackballs that require outputs to be pulled down to
logic ground may be accommodated by placing the jumper on to
the center pin and the pin to the left of the header (active high).

Spinner Control

The section labeled "Spinner Control"
is used to adjust spinner use and
movement. The spinner can be defined
to function as the mouse wheel or as
either mouse axis. This selection is made
using the option buttons. The spinner axis can also be reversed in
the same manner as the trackball axes.
