Controllers
The 3M™ MicroTouch™ EX712 controller provides a drop-in replacement for an
existing controller with wide dynamic range, increased noise immunity, wide operating
temperature stability, reprogrammability using software utilities and improved capability
in ungrounded environments.
The EX712 suface capacitive controller firmware is optimized for surface capacitive
sensors integrated in the latest flat panel displays.
This chapter covers the following EX712 controller specifications:
•
Cable connections
•
Mounting requirements
•
Power requirements and options
•
Status LED codes
Overview of the EX712 Controller
Note:
For complete specifications for the EX712 controller, refer to the appendix at the
end of this manual.
The EX712 controllers and sensors are supplied separately. A 25-point linearization
procedure has been performed to determine the physical properties of the sensor, and the
data is stored in a 2D bar code label attached to the flex tail.
The EX712 controller is available in N81 Format Tablet uncased without cable for
mounting within a custom chassis.
To integrate and test the EX712 controller, you need the following items:
•
A 3M™ MicroTouch™ surface capacitive sensor. These sensors are available in a
variety of sizes.
•
A method of establishing the serial data communication between the controller and
your system. The standard 3M™ MicroTouch™ RS-232 serial cable (P/N 7310101)
is recommended.
