GPSolution is provided to facilitate your interaction with the MiLLennium-GLONASS GPSCard. However, it
certainly is possible to communicate with it through DOS or a Windows-based communications program; this is
discussed in greater detail later in this section.
4.3.1 POWER-ON
The GPSCard's software resides in read-only memory. As such, the unit "self-boots" when turned on and
undergoes a complete self-test. If an error condition is detected during a self-test, the self-test status word will
change; this self-test status word can be viewed in the RGEA/B/D and RVSA/B data output logs (please refer to
the MiLLennium Command Descriptions Manual). If a persistent error develops, please contact your local NovAtel
dealer first. If the problem is still unresolved please contact NovAtel directly through any of the methods in the
Customer Service section, Page 7.
When the GPSCard is first turned on, no activity information is transmitted from the COM ports except for the port
prompt; the external data communications equipment screen will display one of these two messages:
Com1> if connected to COM1 port,
or
Com2> if connected to COM2 port
Either prompt indicates that the GPSCard is ready and waiting for command input.
Commands are typed at the interfacing terminal's keyboard, and sent after issuing a carriage return command
which is usually the same as pressing the terminal's Return or Enter key.
