CHAPTER 2
Integrating the 3M™ Multi-Touch Controller
PX5nnn
The 3M PX5nnn controllers provide a functional equivalent touch controller with wide
dynamic range, increased noise immunity, wide operating temperature stability,
reprogrammability using software utilities and improved capability in ungrounded
environments.
The firmware for the 3M PX5nnn controller is optimized for projected capacitive sensors
integrated in the latest flat panel displays. The performance is controlled by firmware and
can be customized for user applications.
This chapter covers the following 3M PX5nnn controller specifications:
•
Cable connections
•
Mounting requirements
•
Power requirements and options
Overview of the 3M PX5nnn Controllers
The 3M PX5nnn controller has a built-in Universal Serial Bus (USB) full speed interface.
A full speed USB interface has a data rate of 12 Mb/s.
To integrate and test the 3M PX5nnn controller, you need the following items:
•
A 3M™ Multi-Touch Projected Capacitive Sensor
•
A method of establishing the data communication between the controller and your
system.
•
The controller will operate with the standard USB +5V bus power.
•
Many operating systems, including Microsoft
provide support to the touch controllers – No additional software is needed. Contact
