Configuring Power-Up State
 
The NetScan has an internally stored factory default configuration which can be recalled at any time.  You can
program the NetScan to power-up in a “user-defined” state, or if desired, can configure the unit to power-up
with the default configuration.
 
During normal operations the factory defaults may be recalled by issuing the Restore Factory Defaults (*F)
command.  When this command is processed the NetScan will load the factory default configuration and will
operate accordingly.  This command, however, may not be issued while an acquisition is currently configured.
 
 
Usually the NetScan is configured to power-up with the last known configuration at the time that it was
powered-down (or at the time that a *R is issued).  However, you can configure the unit to always power-up
with the factory default configuration by issuing the Power-up Settings (*S1) command. Issuing an *S0
(power-up under last-known configuration) command causes the unit to power up under the last known
configuration
 
 
Note:
Configuring the NetScan to power-up under the factory defaults or recalling the factory
default settings will not affect pre-existing calibration factors of the NetScan or its slave units.
 
 
The following table lists the execution steps and effects when the NetScan is configured to power-up under the
factory default configuration.
