Track Ball Products > DTXX Button Configuration

On the bottom of the unit, there is a 2-position slide switch used to configure the order and function of the trackball buttons, and an 8-position slide switch used to configure the operation and computer interface of the trackball.

The buttons on the DTXX(A) are related to the buttons on a typical mouse as shown in the following figure. In order to facilitate 'right' or 'left' handed operation (or user preference) the order and function of the switches can be changed by setting the 2-position slide switch on the bottom of the trackball as shown above:

Note that the DTXX(A) has a fourth button labeled 'D', which refers to the 'DRAG' button. When this button is pressed simultaneously with any of the other three function buttons (L,M,R), it will lock that function button 'down', until the function button is pressed again, releasing it. This feature is useful when capturing an object on the screen and 'Dragging' it to a new location, since holding a button down while rotating the ball is somewhat difficult.
