Starter Kit
6. At the DOS prompt, type A:\INSTALL. The executable program creates a sub
directory called TOOLKIT and installs the tool kit files.
7. Type the appropriate path name to execute the TSIPCHAT program (e.g.
C:\TOOLKIT\TSIPCHAT). TSIPCHAT provides full access to the TSIP protocol. It
converts binary TSIP packets into printable ASCII characters and vice versa.
When TSIPCHAT is initiated, it configures the PC serial port to the default TSIP
settings (9600 baud, 8-Odd-1).
8. After the TSIPCHAT title screen appears, press [?], and the primary TSIPCHAT
screen shown in Figure 1-11 is displayed.
9. To test the connection, press [V]. This message requests the firmware version
numbers from the GPS module. If connected and operating properly, the module
should respond with a software version report within one second. This report will
be displayed in the command window.
When a GPS antenna is connected to a receiver and has achieved a position fix, the
transmitted position reports scroll through the report window (see Figure 1-11). These
reports include position, velocity and other GPS information. A receiver health report is
sent every few seconds, even when no satellites are being tracked.
Figure 1-11. TSIPCHAT Command Window and Report Window
The upper (shaded) portion of the screen is the command/response window and the lower
portion of the screen is the automatic report window (auto window). The auto window
displays a running account of the messages which are automatically output by the GPS
module in the lower half of the screen. The most common reports are the position and
velocity reports. Other automatic reports include receiver status and health information.
