GPS Master Development System
Software User's Guide
Introduction
This software is designed to interface with a Linx GPS /GNSS module
Master Development System and to display the location and navigation
data provided by the module. Documentation for the module can be found
by clicking the “Software Help” label at the top of the main window.
The Program Interface
When the program starts, the screen in Figure 1 appears.

Figure 1: The Initial Screen
The Master Development system board should be plugged into a USB port
on the computer. Start by selecting the COM port from the drop-down
menu (1). The software establishes a connection to the board through the
USB interface and initiates communication with the module. If successful,
the button is displayed as “Reading GPS” (2). If the attempt fails, the button
is displayed as “GPS Paused”.
Please note that the data routing switch on the development board must
be set to “USB CONTROL”.

Figure 2: The Connected Screen
1. This area displays the data from the module. This includes the
navigation and position information, as well as time, date and satellite
data.
2. This is a list of information on the available satellites displayed in a bar
graph format. This includes the satellite ID, its azimuth and elevation,
and its signal to noise ratio. Each satellite is color coded according to
how the receiver is using it. A satellite that is being tracked and used
for a position fix is green. A satellite that is being tracked, but not used
for a fix is in yellow. A satellite that is not being tracked or used is in
red. The more satellites that are used for a fix, the more accurate the
fix.
3. This is a polar plot showing the location of the satellites in view relative
to the receiver’s position. The satellite’s ID number is shown and is
color coded as described above.
4. This is a box that shows the NMEA data received from the module.

5. This drop-down menu controls how receiver output messages are
displayed in the message display window. This does not control what
the module outputs, just how the data is displayed in the window.
Figure 3: The NMEA Data Display Menu
The all NMEA records received option displays all of the NMEA
messages from the module. The messages are grouped by update.
Individual messages can be displayed with each parameter broken out
for detailed viewing.
Raw (non-parsed) receiver output can be displayed for development
debugging and troubleshooting.
Please see the module’s data guide for more information on these and
other options.
6. The Restart module menu allows the user to force the receiver into
specific start modes; Hot Start, Warm Start, Cold Start or En. Defaults.
7. This menu gives the available baud rates of the module. It may be
necessary to increase the baud rate and decrease the number of
messages displayed if an update rate higher than 1Hz is available and
going to be used. The display on the development system board only
operates at 9,600bps.
8. This menu shows which COM port the computer is using to
communicate with the module. This can be changed if there are more
than one modules connected to the computer.
9. This button starts and stops communication with the module.
10. Clicking this button opens the Google Maps web site and the current
position is displayed. All of the features of Google Maps are enabled,
such as multiple views, zooming, and printing. Note that the PC
running the software must be connected to the Internet for this to
open. If the coordinates are not valid, then a message box will open
stating the invalid coordinate error.
11. Clicking this label opens the Linx Technologies website where
additional information can be found (www.linxtechnologies.com).
