APPENDIX C: GPS 10 AND WINDOWS SERIAL MOUSE ISSUE
Problem:
It is possible for Windows to incorrectly interpret the NMEA 0183 output of the GPS 10 as the
output of a Microsoft Serial BallPoint Mouse. When that happens, Windows loads drivers for the Serial
BallPoint 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 the
GPS 10 to the serial communications port. This problem is not specific to the GPS 10. Any NMEA 0183
device connected to a Windows computer’s serial port is likely to cause this problem. Below are several
possible solutions to this problem.
Note:
If your GPS 10 came with Garmin nRoute™ Navigation Software, you will not have this problem
because the unit is programmed to produce data according to the binary format that is described in
Appendix B: Binary Phase Output Format.
If you wish to use a different navigation software application with your GPS 10, you will need to de-select
the “Phase Output Data” 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 the
wild 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
Device
Manager.
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 the
operating system is completely booted up and running. Every time you use the GPS 10, you will need to
start the computer and operating system before making the connection between the GPS 10 PC and the
computer. 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 0183
data to the computer (change the default configuration to enable “Phase Output Data”). Use the Garmin
Sensor Configuration Software, named SNSRCFG.EXE, provided on the Web site to enable “Phase Output
Data.” SNSRCFG.EXE is included with the latest GPS 10 firmware.
Please note that by enabling “Phase Output Data,” the device will no longer appear as a NMEA 0183
device to your computer. As a result, mapping applications that expect to hear NMEA 0183 data will not
recognize your GPS 10 until you re-enable the NMEA 0183 output, disabling the “Phase Output Data” in
the process.
Refer to
Appendix D: Sensor Configuration Software
for complete information about downloading the
Sensor Configuration Software application.
After the Sensor Configuration Software is installed and running on your computer, follow the steps below
to 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 the
default configuration file for the GPS 10, as shown on
the next page.
2.
Select
Config
>
Switch to NMEA Mode (
or press the
F10 key).
3.
Select
Comm
>
Setup
to open the Comm Setup
Window.
