The 3M™ MicroTouch™ EX serial 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 EX122 and EX112 series capacitive controller firmware is optimized for surface
capacitive sensors integrated in the latest flat panel displays.
This chapter covers the following EX serial controller specifications:

Overview of the EX Serial Controllers
Note:
For complete specifications for each of these EX serial controllers, refer to the
appendices at the end of this manual.
The EX serial 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 EX122 is available in N81 or N72, Format Tablet, cased or uncased for either
external or internal mounting.
The EX112 is available in N81 Format Tablet uncased without cable for mounting
within a custom chassis.
