Overview of the RX141 Controller
The RX141 controller is an uncased device using a USB interface.
To integrate and test the RX141 controller, you need the following items:
•
A 4-wire resistive sensor.
•
A method of establishing the USB communication between the controller and your
system. The standard 3M™ MicroTouch™ USB communications cable
(P/N7319420) is recommended.
•
A software utility or driver with a calibration routine.
Note: You can use MicroTouch™ Software, which includes the touch 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 RX141 has a 4-pin sensor connector (JP6),
and a 5-pin USB cable connector (JP7).
