190-00516-00 GPS 10 Technical Specifications Rev. BPage 23APPENDIX C: GPS 10 AND WINDOWS SERIAL MOUSE ISSUEProblem: It is possible for Windows to incorrectly interpret the NMEA 0183 output of the GPS 10 as theoutput of a Microsoft Serial BallPoint Mouse. When that happens, Windows loads drivers for the SerialBallPoint Mouse. This causes the cursor to move erratically about the display, clicking, right clicking,double clicking, dragging and dropping displayed items as it goes. On Windows 2000 and Windows XP,you may not experience the problem if you wait until after the computer is booted before connecting theGPS 10 to the serial communications port. This problem is not specific to the GPS 10. Any NMEA 0183device connected to a Windows computerís serial port is likely to cause this problem. Below are severalpossible solutions to this problem.Note: If your GPS 10 came with Garmin nRouteô Navigation Software, you will not have this problembecause the unit is programmed to produce data according to the binary format that is described inAppendix B: Binary Phase Output Format.If you wish to use a different navigation software application with your GPS 10, you will need to de-selectthe ìPhase Output Dataî option that is discussed in Solution 3 below.Solution 1: The easiest solution is to disable the Serial BallPoint mouse in the Device Manager. Of course,this solution assumes that you do not need to use a Serial BallPoint mouse with your computer. When thewild mouse problem occurs follow the steps below.1. Unplug the DB9 connector.2. Right-click on the My Computer icon on your desktop and select Properties to open the DeviceManager.3. Go to the hardware tab of the resulting pop-up window and click on the Device Manager button.4. Right-click on Serial BallPoint Mouse and choose the option to Disable (NOT uninstall) this device.Solution 2: Do not plug the DB9 connector into the computer until the computer is turned on and theoperating system is completely booted up and running. Every time you use the GPS 10, you will need tostart the computer and operating system before making the connection between the GPS 10 PC and thecomputer. This solution usually works on Windows 2000 and Windows XP computers.Solution 3: Change the default output of the GPS 10 so that it does not automatically send NMEA 0183data to the computer (change the default configuration to enable ìPhase Output Dataî). Use the GarminSensor Configuration Software, named SNSRCFG.EXE, provided on the Web site to enable ìPhase OutputData.î SNSRCFG.EXE is included with the latest GPS 10 firmware.Please note that by enabling ìPhase Output Data,î the device will no longer appear as a NMEA 0183device to your computer. As a result, mapping applications that expect to hear NMEA 0183 data will notrecognize your GPS 10 until you re-enable the NMEA 0183 output, disabling the ìPhase Output Dataî inthe process.Refer to Appendix D: Sensor Configuration Software for complete information about downloading theSensor Configuration Software application.After the Sensor Configuration Software is installed and running on your computer, follow the steps belowto change the default data output of the GPS 10.1. Select the GPS 10 from the list of sensors and click OK.The Sensor Configuration Software opens with thedefault configuration file for the GPS 10, as shown onthe next page.2. Select Config > Switch to NMEA Mode (or press theF10 key).3. Select Comm > Setup to open the Comm SetupWindow.
