GPSolution is provided to facilitate your interaction with the receiver. 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.
POWER ON
The receiver’s software resides in read-only memory. As such, the unit “self-boots” upon power-up and undergoes a
complete self-test. If an error condition is detected during a self-test, the self-test status word would 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 NovAtel Customer Service.
When the receiver is first powered up, 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 receiver is ready and waiting for command input.
Commands are typed at the interfacing terminal’s keyboard, and sent after pressing the terminal’s Return or Enter key.
Note: Most valid commands do not echo a response to a command input; the indication that they have been accepted
is a return of the port prompt from the receiver. VERSION, HELP and ? are the only commands that do
provide a data response other than the port prompt.
