APPENDIX B: GPS 10X AND WINDOWS SERIAL MOUSE ISSUE
Problem:
It is possible for Windows to incorrectly interpret the NMEA 0183 output of the GPS 10x 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 10x to the serial communications port. This problem is not specific to the GPS 10x. 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 you are using Garmin nRoute™ Navigation Software with your GPS 10x, you will not have this
problem because the unit is programmed to produce data according to the binary format that is described in
Appendix A: Binary Phase Output Format
If you wish to use a different navigation software application with your GPS 10x, 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 10x, you will need to
start the computer and operating system before making the connection between the GPS 10x PC and the
computer. This solution usually works on Windows 2000 and Windows XP computers.
Solution 3:
Change the default output of the GPS 10x 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 10x 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 10x until you re-enable the NMEA 0183 output, disabling the “Phase Output Data” in
the process.
Refer to
Appendix C: 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 10x.
1.
Select the
GPS 10x
from the list of sensors and click
OK.
The Sensor Configuration Software opens
with the default configuration file for the GPS 10x, 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.
