Page 9: Chapter 1 Integrating The Rx151 Controller
• A 5-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. -

Refer to Appendix A for further specifications. Establishing the Data Connection The RX151 controller requires a 3M™ MicroTouch™ USB communication cable (P/N 7319420) PC 99 compatible or an equivalent interconnect. One end of this cable plugs into the USB connector (JP7) on the RX151 controller. -
Page 11: Mounting The Controller
3M™ MicroTouch™ Controller RX151 Reference Guide Mounting the Controller The controller is designed for internal mounting only. Choose a convenient spot away from high-voltage, high power cables and electronics. Use 4-40 metal screws to mount the controller using the two diagonal mounting holes in the board. The controller should be mounted in line with the sensor cable exit point to minimize cable flexing. -
Page 12: Turning On Your System
Status Light (LED) Diagnostics 3M™ MicroTouch™ controllers are highly reliable units; however, there may be occasions when the controller does not perform exactly as you expected. The RX151 controller provides diagnostic feedback with a light emitting diode (LED) on the component side of the board that indicates the status of the sensor. -
Page 13: What's Next
What's Next? Since this is a HID (human interface device) compatible controller, the controller will operate independent of a 3M™ MicroTouch™ driver. You must obtain a HID calibration utility from the 3M Touch Systems website. Additional 3M Touch Systems documentation is available from the corporate website at www.3Mtouch.com. -

HID. The only required software is a calibration tool used for aligning the sensor to the display. This calibration tool is available from 3M Touch Systems. Receiving Reports from the Controller The controller sends a variety of reports to the computer. - Page 17 3M™ MicroTouch™ Controller RX151 Reference Guide HID-Compatible Coordinate Data – Report 1 This is used to transfer the 10-bit coordinate data to the host. This report, when activated, is sent to the host whenever new data is available/scheduled for transmission. It is an asynchronous report that is activated by default at power up.

3M™ MicroTouch™ Controller RX151 Reference Guide Note: The Touch_Reports_Utility command causes the controller to send Report 7 from the endpoint 0 exclusively. This action is essential in getting a calibration utility to function. The endpoint 1 does not send any reports at this time. The Touch_Reports_Restore command causes the controller to send the previously active asynchronous report (REPORT_ID_HID or REPORT_ID_PACKED) from endpoint 1. - Page 21 3M™ MicroTouch™ Controller RX151 Reference Guide Offset Field Size Value Description wIndex Always 0 wLength Always 8 Table 12.
