WELCOME
Thank you for purchasing a Globalsat USB GPS receiver! Globalsat USB GPS receivers allow for
real-time street navigation by using your laptop for graphical plotting and positioning of your route.
Simply load the GPS driver, plug the GPS receiver into your computer’s USB port and install your own
personal mapping software to begin to view your position in real-time in relation to the surrounding
streets in your travel area.
You’ll find that almost any NMEA compliant mapping/charting softw are will be compat ible with y our
USB GPS receiver. Visit our web-site for recommended mapping programs that you can use.
http://www.usglobalsat .com/f aq_det ails/Mapch art.asp
1. GETTING STARTED
These are only a few simple steps that you need to follow before using your USB GPS receiver:
Install the USB driver and o nto your lapto p from the includ ed CD-R OM or dow nload th e files from our
web-sitewww.usglobalsat.com/mac
Plug-in the GPS receiver into your laptop.
NOTE: From within your mapping, or navigation software (including the supplied GPS Information
utility), you will need to manually configure the selection of the COM port to what was assigned to the
GPS receiver so that proper communication between the GPS receiver and mapping program can
occur. Most all software requires that you manually configure the COM port setting for any GPS device
you use.
IMPORTANT:
You must change the default rate setting of your mapping software to 4800 if this is not current ly set as
such otherwise GPS data cannot be received.
Port: /dev/cu.usbserial
Set Baud Rate: 4800
2. INST ALLING THE USB DRIVER T O Y OUR LAPT OP
STEP 1.

When installation is complete, reboot your Mac and connect your USB GPS receiver at this stage for
device detection.
NOTE: After completing driver installation under Mac OS 10.2.X, a warning may appear stating that
“Prolific USBSerial.kext” has encountered problems. This is due to driver being compiled under OS
10.1.X. Three options will be provided for you to select one; how ever selecting the “Fix and Use”
option will eliminate this conflict.

information can be found under USB Device window.
4. UN-INST ALL THE USB DRIVER
To uninstall the Prolific USB driver, follow these steps:
Open "Applications-> Utilities-> Terminal". You need to create ID & password first on NetInfo Manager.
Login to root user and type "su" and enter password.
Type "cd /System/Library/Extensions" to go to the "Extensions" folder.
Unload the driver (if it had been loaded) by typing "kextunload PL2303.kext" or "kextunload
ProlificUsbSerial.kext"
Remove the driver by typing "rm -r PL2303.kext" or "rm -r ProlificUsbSerial.kext".
See FAQ below for more on “root users”
5. INST ALIZING YOUR GPS REC EIVER
Before using your USB GPS receiver for navigation (especially for the first time), the receiver must
obtain a local GPS fix (coordinates) of the current position. To do this, take your laptop (with your USB
driver and the mapping software loaded and configured) to an open area that has a clear view to the
sky (such as a park or empty field). St art you r softw are (o r the in clud ed Mac_ GPSut ility progra m) and
wait for initialization of the GPS to complete. This may take a few minutes depending on various
factors such as the distance of the current coordinates from the last time the GPS receiver was
Page 8
activated, GPS signal strength and surrounding terrain (tall trees and buildings can block the satellite
signals). Once the RAW GPS data is displayed onto the screen, if applicable for your software, a fix has
been initialized (red LED on the GPS will also start to flash). In some cases initialization can take up to
several minutes depending on the conditions mentioned above before complete GPS data will be
displayed on the screen.
Coordinates scrolling with zero’s means that the port connection is cormplete but the satellite data is
not being received yet (possibly still initializing or in a bad area for satellite reception).
6. USING Y OUR GPS RECEIVER
Once the USB GPS receiver’s driver and your personal mapping software have been installed and
configured properly, you can begin to use your navigation system by plugging the USB GPS into your
laptop’s USB port and launching your mapping software. If you don’t have a mapping, or navigation
software, we’ve included a GPS test utility called “GPS Utility” so that you can test the function of your
USB GPS receiver. This utility is located within the Mac directory on the CD-ROM or can be download
from our web-site www.usglobalsat.com/mac
GPS LED Status indicator:
LED OFF: GPS receiver is off (no power).
LED ON (solid): No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
Always select an area in the vehicle where the GPS unit will be secure and not obstruct normal driving,
visibility and safety, but still maintaining a “view to the sky” in order to receive satellite data.

7. F AQ’ s
How Do I Enable a Root Account? The "root" user (also known as the supe r user) is th e most
powerful UNIX account. The root account can do anything to any file or folder, anywhere on the system.
For that reason, Globalsat/USGlobalsat cannot recommend, nor support users who attempt
modifications of the ‘root user” as it's considered quite dangerous, and only needs to be used
(occasionally) by advanc ed use rs.
Because of the dangers of operating as root, Apple has chosen to hide the root account in OS X Final.
However, there are a number of ways to enable it. The easiest is to boot off the install CD, and look
under the Install menu for the "Password Reset" option. You can use this to change your own
password if you forget it, and to enable the root account. This utility will not run if you copy it to your
hard drive! It only works when booting from the CD.
Read the rest if you'd like to know how to do this from within OS X, and skip the CD-based reboot.
The second easiest way to enable root is to start a terminal session, a nd type: sudo passwd root
You will be prompted for a new password to enable root access. Many find this easier than rebooting,
but since it involves the command line, newcomers may find it a bit more i ntimidati ng.
The hardest way to enable root is to use the NetInfo Manager application (in Applications/Utilities).
Here's what you do, courtesy of "anonymous":
1) Open NetInfo Manager
2) Select "Users" from the second list.
3) Select a user you created and know the password for!
4) Double-click on the value across from "passwd" and copy it. It is the encoded form of the password
for that user.
5) Select "root" from the list of users. Find the "passwd" value (default is "*") and paste over it.
6) Exit NetInfo Manager.
7) Open the Terminal and type "su root".
8) Enter the password for the user chosen above.
Will the USB GPS work with other Street Mapping software?
Page 9
Globalsat USB GPS rece ivers p rovides standa rd NMEA data fo r mapp ing softw are to use and c onvert
to coordinates and should work well with most any NMEA compliant software on the market today.
How accurate is the GPS?
The USB GPS is WAAS/EGNOS capable, and for units sold in North America through authorized
resellers, these unit s are W AAS/EGN OS en abled u nless otherw ise s tated. Accu rac y can be u p to 5
meters 3D RMS with WAAS enabled and 10-15 meters 2D RMS WAAS disabled
What is ideal GPS environment?
The GPS requires an open, clear view of the sky. Buildings, covered parking areas, tunnels and dense
foliage can cause the GPS receiver to be unable to get a location fix.
If you are parked in a covered parking lot or near a tall building, it is recommended that you drive away
until you have a clear view of the sky before using the BU-303. You may need to give the GPS a few
minutes to find or get a fix its location.
How do I know if the GPS is ON?
Your USB GPS must be plugged into your laptop’s USB port to get power. If your PC is on and the
COM port was configured properly, the GPS receiver is on and receiving the streaming GPS data. This
can be verified by opening your mapping software program. In addition, the Globalsat USB GPS has a
built-in LED status indicator that shows the following:
LED OFF: GPS receiver is off (no power).
LED ON (solid): No fix, searching for GPS signals.
LED FLASHING: Position fix established and GPS signals are being received.
Why does the GPS not work near buildings and other tall objects?
The GPS uses satellites in the space to find out where it i s. Therefore it nee ds a clear view of the sk y.
Tall buildings and other objects that block the receiver’s view to the sky make it infeasible to determine
your location. Sometimes the satellites are not overhead but near the horizon. In these cases the GPS
must have a clear view of the horizon.
What driver is needed for Virtual PC?
For Macintosh Virtual PC applications, you do not need any additional drivers than those already being
used for your Mac OS X applications. It is, however recommended that 1-Gigabyte of memory is
available to run Virtual PC applic ations effi ciently.
