  • Page 3: Chapter 1: Operation Overview

    Bit Pad Two 3 Chapter 1: Operation Overview The Bit Pad Two is a data tablet that acts as an input device. It allows for the translation of graphic information into digital, suitable for a digital device such as a computer. The Bit Pad Two is valuable in many applications, including: Steering a cursor on a computer terminal.
  • Page 4 Bit Pad Two 4 Power Supply: Source of power for the Bit Pad Two. It attaches to the data/power cable and the power line. Adapter Cables: Cable assemblies that can change the gender of the data/power cable connector; reverse the communication lines or convert the power supply plug to the international standards.
  • Page 5 Bit Pad Two 5 Reports are in counts of resolution, expressed as absolute coordinates or relative coordinates. Resolution: Smallest distance or movement that the data tablet can distinguish. Resolution is a measure of precision and is expressed in lines per inch (lpi) or lines per millimeter (lpmm).

  • Page 6: Chapter 2: Configuration Parameters

    Bit Pad Two 6 data tablet is in Absolute Mode. Reports are in relative coordinates when the data tablet is in Relative Mode. Absolute and Relative modes are two of the Bit Pad Two’s many operating characteristics. Other operating characteristics govern when reports are issued; how fast they are issued and the tablet resolution.

  • Page 7: Section B: Remote Control

    Bit Pad Two 7 to report the proximity status. Reports in the ASCII BCD format use the cursor/stylus flag character to identify an out-of-prox report. Section B: Remote Control The data tablet can be configured to accept or reject commands from the host. When the remote control is enabled, the data tablet is receptive to commands from the host.

  • Page 8: Section E: Hardware Interface

    Bit Pad Two 8 If the switch is set to enable CTS handshaking, the data tablet awaits CTS from the host before it can issue reports. If CTS is not asserted, the data tablet is inhibited from sending reports. If the switch is set to disable CTS handshaking, the data tablet ignores the CTS line. Section E: Hardware Interface The Bit Pad Two has an RS-232C interface.

  • Page 9: Signal Levels

    Bit Pad Two 9 An adapter cable is available to change the connector gender from female to male. Also, a reversing cable is available to reverse the communications lines; its pin assignments appear below: RS-232C Reversing Cable – Pin Assignments for the 25-Pin D Connector Signal Levels The table below specifies the signal levels for data transmissions: RS-232C Signal Levels...

  • Page 10: Section F: Report Format And Cursor Output Codes

    Bit Pad Two 10 Section F: Report Format and Cursor Output Codes Two report formats are available: packed binary and ASCII BCD. NOTE: To users of other Summagraphics data tablets or digitizers: the formats described here are specific to the Bit Pad Two and Bit Pad One. Other Summagraphics products have similarly named formats, but their content may be different.
  • Page 11 Bit Pad Two 11 Least significant bit Most significant bit Proximity, 0 when in proximity and 1 when out-of-prox Flag bit, identifying the stylus or cursor buttons being pressed. The cursor output codes are switch selective: *On the 3-button cursor, the buttons are distinguished by raised dimples, rather than by numbered labels.

  • Page 17: Chapter 4: Operating Characteristics And Commands

    Bit Pad Two 17 Chapter 4: Operating Characteristics and Commands Bit Pad Two has a variety of operating characteristics and functions. The operating characteristics control the report flow, report content and tablet resolution. Set the Bit Pad Two’s operating characteristics or initiate the functions with commands from the host or with the switches inside the tablet.

  • Page 18: Section A: Controlling The Report Flow And Content

    Bit Pad Two 18 Each characteristic or function and its commands are defined. For easy reference, the commands appear in ASCII and hexadecimal. Appendix B ASCII Conversion Chart also provides the binary, decimal and octal conversions. A summary of the commands and switch settings appears in Appendix D Quick Reference Sheet.
  • Page 19 Bit Pad Two 19 Switch Setting: Report Rate: DIP #1 Stream Mode: Switch Stream Mode: Please note that one command sets both the mode and Report Rate. However, five switches must be set to accomplish the same setting, two for the mode and three for the Report Rate.
  • Page 20 Bit Pad Two 20 Report Rate The Report Rate is the number of reports the data tablet issues each second. Use it with Stream or Switch Stream modes. Note that the Report Rate settings, such as 2 rps or 70 rps, are approximations.

  • Page 21: Point Mode

    Bit Pad Two 21 Point Mode Command: Switch Setting: In Point Mode, the Bit Pad Two issues one report each time a cursor or stylus button is pressed. Reports can be issued up to the maximum Report Rate available for the set baud rate.

  • Page 22: Relative Mode

    Bit Pad Two 22 In Absolute Mode, the Bit Pad Two issues reports as absolute coordinates. Absolute coordinates are measured relative to the tablet origin. Reports issued from out-of-prox are repeats of the last valid coordinate pair. NOTE: When reports are in binary format and the data tablet is in Absolute Mode, the maximum reportable value is 4095.

  • Page 23: Increment Mode

    Bit Pad Two 23 The effect is a restriction of the maximum delta between reported points. The delta is the distance from the last report to the current one. The maximum delta varies, depending on the tablet’s resolution setting. This relationship is quantified in the table below: Increment Mode Command: Switch Setting:...
  • Page 24 Bit Pad Two 24 Here’s a description of how Increment Mode works: last report issued becomes the center of an imaginary square whose sides are twice the increment value. The cursor can move anywhere inside the imaginary square without a report being issued. As soon as the increment is satisfied along either axis, the Bit Pad Two transmits the actual X and Y coordinates of the point.

  • Page 25: Section B: Combining Characteristics

    Bit Pad Two 25 (30,7) The increment is satisfied from the last point along the X axis only; the Bit Pad Two issues the new report. (32,17) The increment is satisfied from the last point along the Y axis only; the Bit Pad Two issues the new report.

  • Page 26: Section C: Other Commands

    Bit Pad Two 26 When the data tablet is in Remote Request and Increment modes, regardless of  whether the increment has been satisfied or not, the actual position where the stylus or cursor is when the data tablet receives the remote trigger is reported position.

  • Page 27: Resolution Send Configuration

    Bit Pad Two 27 Send Configuration Command: Switch Setting: Use the Send Configuration command to send a report to the host that identifies the data tablet model and its version of software. The output looks like this: MM1103_BIT_PAD_II_by_Summagraphics_Version_n.n<CR><LF> The underlines are spaces; n.n is the version number and the line feed is switch-selective. Transmission Control Command: Switch Setting:...

  • Page 28: Reset

    Bit Pad Two 28 The data tablet will respond to other commands, such as a command to change the resolution, while it is on standby. If the Reset command is issued while the data tablet is on standby, the data tablet honors the Reset command, but does not retract the XOFF state. Reset Command: Switch Setting:...

  • Page 29: Checking The Data Tablet

    Bit Pad Two 29 Chapter 5: Checking the Data Tablet A convenient functional check of the data tablet can be performed by connecting Bit Pad Two to a terminal and moving the cursor or stylus across the tablet’s active area. (The output is easier to interpret if you have the report format set for ASCII BCD.) The X and Y values should increase as the cursor or stylus slides from the tablet origin toward the end of the axis.

  • Page 31: Section B: In Case Of Failure

    Bit Pad Two 31 If the Self-Test output byte is an ASCII O or G, the data tablet passed the diagnostic tests. (An O simply indicates that the stylus/cursor is in proximity. A G indicates that it is out-of- prox.) Section B: In Case of Failure If the Bit Pad Two does not operate or fails the Self-Test, follow these steps: 1.
