Connecting the Touchscreen Cable
The touchscreen connector (JP4) is a 5-pin AMP 103634-5, locking right
angle male connector with pins on 0.1 inch centers.
The MT3000 controller supports exiting the flex cable in any direction from
the touchscreen– from the top, bottom, left or right. The standard
configuration is with the flex cable exiting from the right side of the sensor,
(3 o’clock position) when viewed from the front.

If you exit from another direction, the controller firmware automatically
determines the pinout configuration when you calibrate the touchscreen
with TouchWare or your equivalent software. This permits flexibility in
orienting the sensor and in mounting the controller to conform to your
hardware requirements.
The automatic pinout configuration feature resides in the controller and is
independent of the driver you are using.
MicroTouch can provide software for performing a 25–point linearization
procedure by the customer, although this is not required with a mated
controller and sensor.
Caution:
If you are equipped to perform a 25–point linearization and
decide to do so, you must orient the sensor with the tail exiting to the right
during the procedure. After linearization, you can re-orient the screen as
required by your OEM design.
