5.1.4 @ - Displaying and Changing Current Major Mode
The @ command provides developers with a simple way of switching modes enabling on–
the–fly testing of code.
For information on the top level RVP900 see SOPRM command word #9 in 8.4 Setup
Operating Parameters (SOPRM) (page 239). This question allows you to use the mode that
has been selected by that command, or to force the use of a particular mode.
5.2 Managing Settings with M Menus
You can use the M menus to view and modify current settings.
Type ?? to print the entire set of questions
The M menu works from the current parameter values, not from the saved values in non-
volatile RAM. If the host computer has modified some current values, you see these changes
as you browse the setup list.
Vaisala recommends making incremental changes to saved settings.
1. Type R to restore the saved values.
2. Type M to make the changes starting from that point.
The current value of each parameter is displayed on the screen. The TTY pauses for
input at the end of the line:
• Press RETURN to move to the next parameter and leave the present parameter
unchanged.
• Type U to move back up in the list, and
• Type Q to exit the list at any time.
• Type a number or a YES/NO response to change the parameter's value, and displays
the line again with the new value.
An error message is displayed if entries are invalid.
3. Type S to save the new values.
You must exit the menus using the Q before resuming normal RVP operation.
Portions of the RVP command interpreter continue to run while the menus are active, but
the processor does not function until you exit the menus.
