    Status LED codes Overview of the EX II 3000SP Touch Screen Controller The EX II 3000SP is a form, fit and functional replacement for the TP4+ controller (64-68) with a standard RS-232 serial interface. The EX II 3000SP controller, touch screen, stylus and cables are supplied separately.
  • Page 10 EX II 3000SP Controller Reference Guide Figure 1 Components of the TouchPen System To effectively integrate and test the EX II 3000SP controller, you will need the following items: • A 3M Touch Systems TouchPen (P/N 69-502 with 7311420 cable extension to connect to controller).

  • Page 11: Establishing The Data Connection

    The EX II 3000SP controller requires that an RS-232 serial communication cable be attached to connector JP3. You can use a 3M Touch Systems RS-232 cable (P/N 7311273). One end of this cable plugs into the RS-232 connector (JP3) on the EX II 3000SP controller.

  • Page 12: Mounting The Controller

    The controller should be mounted on the chassis inside the monitor. Supplying Power to the Controller You must supply the EX II 3000SP controller with power internally (+12 VDC) through a custom serial cable configuration. Exact specifications can be found in Appendix A.

  • Page 13: Mounting The Touch Screen

    Adjust the horizontal and vertical position controls on the monitor to center the image on the screen. The EX II 3000SP controller has a light emitting diode (LED) on one edge of the board that indicates the status of the touch screen unit.

    Installing and Using TouchWare TouchWare includes the software driver that lets your touch screen work with your computer. 3M Touch Systems has touch screen drivers for many operating systems, including Windows XP, 2000, 9x, Windows Me, Windows 3.1x, and Windows NT. Be sure to install the correct touch screen software for your operating system.
  • Page 15 For more information on connecting your cables and installing and using the touch screen control panel and utilities, refer to the TouchWare User’s Guide (19-224). All 3M Touch Systems documentation is available from the corporate website at www.3Mtouch.com or from the Touch Solutions CD (P/N 19-640).

  • Page 17: Chapter 2 Ex Ii 3000Sp Controller Communications

    EX II 3000SP controller. Communication Parameters The default operation of the EX II 3000SP controller is N, 8, 1 (no parity, 8 data bits, and 1 stop bits) at 9600 baud. It also can be programmed to work with even/odd parity, 8 data bits, and 1 or 2 stop bits.

  • Page 18: Communicating With The Controller

    • Format Tablet is the standard for current 3M Touch Systems product development and is the format used by all touch screen drivers written by 3M Touch Systems. Operating Mode The operating mode specifies the conditions under which the controller sends the X/Y touch coordinates (input data packet) to the host system.
  • Page 19 The general format of a command is as follows: <Header>Command<Terminator> Note: The following descriptions of header, command, and terminator, use 3M Touch Systems terminal emulator key sequences. You may need to enter the sequence in a different format, depending on your emulator.
  • Page 20 EX II 3000SP Controller Reference Guide 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. The header is the first character in the response string and is the ASCII start-of-header control character SOH.

  • Page 21: Summary Of Firmware Commands

    You should be aware of the results before executing any firmware commands. To optimize the performance of the EX II 3000SP touch screen controller and simplify the development of custom drivers, 3M Touch Systems recommends you use the commands listed in Table 3 for current development.
  • Page 22 EX II 3000SP Controller Reference Guide Table 3 Firmware Commands for EX II 3000SP Development Command Name Code Description Pen or Finger The controller recognizes both TouchPen and finger touch. This is the default setting. Calibrate Extended CX Initiates an interactive, two-point calibration.

  • Page 23: Calibrate Extended

    EX II 3000SP Controller Communications Calibrate Extended Syntax: <SOH>CX<CR> Description: Initiates an interactive, two-point calibration. During the calibration process, you define the active area of the touch screen by mapping locations to an absolute X/Y coordinate system. You touch two target areas on the screen. Touching the target areas sends the X/Y coordinates for those touch points to the controller.
  • Page 24 Touching the two valid calibration points results in a successful calibration. If either calibration point is invalid, the calibration fails. The EX II 3000SP controller restores the factory default calibration. If the Calibrate Extended failed, repeat the CX process.

  • Page 25: Calibrate Raw

    8-bit communication mode. To end Calibrate Raw mode, issue a Reset command. 3M Touch Systems uses the Calibrate Raw command during manufacturing and testing, and recommends you only use this command for diagnostics when you want raw data.

    EX II 3000SP Controller Reference Guide Format Tablet Syntax: <SOH>FT<CR> Description: Outputs the X/Y touch coordinate data in a 5-byte packet. The packet includes 1 status byte and 4 bytes of binary X/Y coordinate data. The protocol also establishes the X and Y coordinate output as 14 binary bits providing a range of 0 to 16,383.

    ROM to the non-volatile memory (NOVRAM) and then executes a Reset command. Table 10 lists the factory defaults for the EX II 3000SP controller. The Restore Defaults command is useful in situations where inadvertent commands to the controller have rendered the touch screen inoperative.

  • Page 32: Unit Type

    EX II 3000SP Controller Reference Guide Unit Type Syntax: <SOH>UT<CR> Description: Responds with an 8-character identity string. This string identifies the type of controller currently attached to the system, lists the features supported by the controller, and outputs the status of the controller hardware (a self-test code).
