A.13 RESTORING DEFAULT CONFIGURATION SETTINGS
You can restore the default factory configuration settings in software and hardware.
• Software—In command mode, use the factory RESET command to restore the
defaults. This command automatically loads the default settings and executes a
save command. Next, send the reboot command so that the module reboots with
the default configuration.
• Hardware—Set GPIO9 high on power up to arm the factory reset function. Then
toggle GPIO9 five (5) times, which restores the configuration to the factory reset.
GPIO9 is sampled at about 1 Hz; therefore, if you are using a CPU to generate the
signal, make sure that GPIO9 transitions (high to low or low to high) are at least 1
second long.
You can specify a user configuration file as the factory reset settings. Prior to this firm-
ware version only the hardcoded factory defaults would be restored. If you have stored
a configuration file named user, the module reads it as the factory default instead of
using the factory hardcoded defaults. If no user configuration file is present, the module
uses the hardcoded factory defaults.
You create the user configuration file using the save user command, which saves the
current configuration settings into a file named user.
Even if a user configuration file exists, arming and toggling GPIO9 7 times overrides
the user settings and restores the module to the factory hardcoded defaults. This
bypass mechanism allows you to restore the factory defaults in case a bad configura-
tion is saved into the user file.
Issuing the factory RESET command while in command mode restores the module to
a factory default state.
