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.
