Overview of the Daughterboard Controller

The Daughterboard controller is a low power, miniaturized board that

is easily integrated onto a system board. The daughterboard design

eliminates the more complicated layout and design issues of a chip set

and interfaces directly with the touchscreen through CMOS

asynchronous serial communication.

The controller supports CMOS communication rather than RS-232

communication. It is fully compatible with all MicroTouch software

drivers and previous controllers. It has a 14-pin dual row male

connector on the component side of the printed circuit board (PCB).

This connector attaches the Daughterboard controller directly to the

system board.

The following illustration shows a touch system configuration with the

Daughterboard controller mounted to the system board.
