150 Programming the Enhanced Monitor
SYSTem:NVSave causes the enhanced monitor to store many of its parameters to
non-volatile memory. This includes temperature limits, current limits, total power
limits, status enable settings, PSC flag, beep frequency, beep duration, system name,
mainframe serial number, and all RS-232 settings.
•
Non-volatile memory has a finite access lifetime. For this reason, these values
are saved only when explicitly requested with this command and all at one
time. The commands/registers affected are:
