3M™ MicroTouch™ Controller RX182 Reference Guide 9

CHAPTER 1

Integrating the RX182 Controller

The 3MTM MicroTouch™ RX182 serial resistive controller is an accurate, small outline, low cost, temperature stable controller capable of supporting a wide range of resistive sensors. It is designed for internal mounting in OEM applications.

This chapter covers the following RX182 controller specifications:

• Cable connections

• Mounting requirements

• Power requirements and options

• Status LED codes

Overview of the RX182 Controller

The RX182 controller is an uncased device using an RS-232 serial interface. The communication parameters for the RX182 are N81 -- no parity, 8 data bits, and 1 stop bit.

To integrate and test the RX182 controller, you need the following items:

• A 8-wire resistive sensor.

• A method of establishing the serial data communication between the controller and

your system. The standard 3M™ MicroTouch™ RS-232 plug and play serial cable (P/N 7319630) is recommended.

• A power source.

• 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 1.6 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 RX182 has a 8-pin sensor connector (JP6), an 8-pin serial plug and play cable connector (JP2), and a 3-pin power connector for selectable input voltages.
