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 instru-
ments.
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 com-
mands, 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.
