Page 9: Chapter 1 Integrating The Rx142 Controller
To integrate and test the RX142 controller, you need the following items: • A 4-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. •... -
Page 10: Handling And Esd Protection
The RX142 controller requires an RS-232 serial plug and play communication cable attached to connector JP2. You can use a standard 3M™ MicroTouch™ RS-232 plug and play cable (P/N 7319630) or an equivalent interconnect. One end of this cable plugs into the RS-232 connector (JP2) on the RX142 controller. -

Page 12: Mounting The Sensor
3M™ MicroTouch™ Controller RX142 Reference Guide CAUTION To avoid possible damage to the controller, you must provide a path for electrostatic discharge (ESD). The controller mounting hole near the sensor connector should be used to connect to chassis safety ground and must be attached by the shortest possible route to a good earth return (chassis) in all applications. -
Page 13: Status Light (Led) Diagnostics
3M™ MicroTouch™ Controller RX142 Reference Guide Status Light (LED) Diagnostics 3M Touch Systems controllers are highly reliable units; however, there may be occasions when the controller does not perform exactly as you expected. The RX142 controller provides diagnostic feedback with a light emitting diode (LED) on the component side of the board that indicates the status of the sensor unit. -

3M™ MicroTouch™ Controller RX142 Reference Guide Installing 3M™ MicroTouch™ Software 3M™ MicroTouch™ Software includes the driver that enables your sensor to work with your computer. 3M Touch Systems has touch drivers for many operating systems, including Windows Vista, XP, XP embedded, 2000, 9X, Windows Me, Windows CE, and Windows NT 4.0 (refer to the website for a complete listing). -
Page 15: Chapter 2 Rx142 Controller Communications
Format Tablet is supported by all current 3M™ MicroTouch™ controllers. • It is the standard for current 3M Touch Systems product development and is the format used by all touch drivers written by 3M Touch Systems. Refer to the Format Tablet command in the firmware reference section. -
Page 16: Communicating With The Controller
Mode Stream provides the best response time and overall feel. 3M Touch Systems recommends that the touch driver generate an interrupt as each packet in the data stream arrives. Because touchdown and liftoff events are specially coded, provided that the interrupts are sent as recommended, your software always knows exactly what the user is doing. -
Page 17: Receiving Responses From The Controller
<Header>Command Response<Terminator> Note: The following descriptions of header, response, and terminator, use 3M Touch Systems terminal emulator key sequences. The format of controller responses varies depending on the terminal emulation mode you are using. -

Enter Sleep Controller enters low power mode. Format Tablet Outputs the X/Y touch coordinate data in a five-byte packet. -
Page 20: Guidelines For The C3 Commands
3M™ MicroTouch™ Controller RX142 Reference Guide In addition to scaling the Format Tablet output to the display, this command corrects for sensor orientation and sensor pinout variations. This information will be maintained by the controller. The Calibrate 3 Point command initiates an interactive calibration procedure which defines the active area of the sensor by mapping locations to an absolute X,Y coordinate system. -

Page 22: Get Controller Number
3M™ MicroTouch™ Controller RX142 Reference Guide The low order bits (X3 – X0 and Y3 – Y0) are not significant in a 1024 by 1024 sensor because data can fluctuate with each touch, and therefore may not be completely accurate. -
Page 23: Null Command
Response: <SOH>CcXxxx<CR> where: = Two ASCII characters that describe the type of 3M Touch Systems controller. Xxxx = This is a unique identifier not necessarily the actual firmware revision number. Description: Returns a 6-character identifier, which describes the controller type and the firmware RX142 version number. -
Page 24: Restore Defaults
Description: Returns to the factory default operating parameters. The Restore Defaults command copies the 3M Touch Systems factory default parameters from ROM to the non-volatile memory (NOVRAM) and then executes a Reset command. The following table lists the factory defaults for the RX142 controller. The Restore Defaults command is useful in situations where inadvertent commands to the controller have rendered the sensor inoperative. - Page 25 3M™ MicroTouch™ Controller RX142 Reference Guide = Two ASCII characters that identify the controller type.
