The combination of folder and file name cannot exceed 240 characters, and

When loading a preferences file that specifies a static IP address for LAN, be
careful that this does not result in two instruments with the same IP address on
your LAN. This could result in LAN configuration errors on both instruments.
User preferences cannot be stored or loaded (retrieved) using the front panel.
Using *SAV and *RCL
Additional commands that can be used to save and recall instrument states are
the IEEE-488.2 common commands *SAV and *RCL. With these commands, up to
five states can be saved and recalled by location number from the counter’s
internal flash memory. States saved using this method can also be specified for
recall at power-on.
*SAV {0|1|2|3|4}
Saves the current instrument state in one of five {0|1|2|3|4} flash memory state
locations. State location ‘0’ is a valid location; however, the instrument state at
power-down is automatically saved in location ‘0’ and will overwrite any state
saved there. All parameters of the counter’s state are saved with the exception of
“user-preference” parameters such as those which configure the front panel
display.
