Overview of the SC500 Touch Screen Controller
The SC500 controller is an uncased device using a USB interface.
To integrate and test the SC500 USB controller, you need the following items:
•
A 3M Touch Systems 5-wire resistive touch screen. The touch screens are available in a
variety of sizes.
•
A method of establishing the USB communication between the controller and your
system. The standard 3M Touch Systems USB communications cable (P/N7319420) is
recommended. This cable is PC99 compliant.
•
A touch screen utility or driver with a calibration routine.
Note: You can use MicroTouch™ Software, which includes the touch screen device
driver and utilities software.
The controller measures 1.3 x 2.4 inches, or 1.3 x 2.7 inches total profile over the
connectors. Allow additional clearance for the mating connectors. The total height
profile is 0.40 inches from the thru hole pins on the trace side of the board to the top
of the highest component on the opposite side. The SC500 has a 5-pin touch screen
connector (JP5), and a 5-pin USB cable connector (JP7).
