Integrators are encouraged to optimize the speed range of DuraPoint to meet
their system's requirements.
The cursor speed of DuraPoint can also be changed in the Windows Mouse
Control Panel.
To change the cursor speed of DuraPoint on the board, first, carefully remove
the solder bridge that connects JP5. Then, solder wires to connect the jumpers
associated with the cursor speed you desire. If a different usage response
range is needed, please contact Interlink Electronics Product Support. Interlink
Electronics can design an optimal speed range for any application.
