consumption will be roughly ¼ the consumption as when N=0. This parameter must be
set to the appropriate value when more than 16 remotes are in use.
set to the appropriate value when more than 16 remotes are in use.
Enable Low Power Acquisition Mode. When a remote is searching for a base to acquire
and register with, it scans the frequency band very rapidly. This mode consumes about
80mA of current during this mode. To reduce the frequency consumption when a remote
is in acquisition mode, a low power acquisition mode is provided. In this mode, the
remote only scans the frequency band every other hop. This will reduce the average
current consumption during acquisition to about 40mA. The tradeoff is it can take twice
as long to acquire and register with a base, or up to 4 seconds.

5.5. Memory Commands
The WIT2492 allows the user to store a configuration in nonvolatile memory, which is
loaded during the initialization period every time the radio is powered up. Note that
changes to the serial port baud rate from recalling the factory defaults or recalling
memory will not take effect until DTR is toggled or power to the radio is cycled.

Recall Factory Defaults
Resets the WIT2492 to its factory default state. This is useful for testing purposes or if
there is a problem in operation of the system and the configuration is suspect. Use the
Store Memory command afterwards if you wish the factory default settings to be
remembered the next time you cycle power or reset the radio.

Recall Memory
Useful for restoring the power-on settings after experimenting with temporary changes to
data rate, protocol or network parameters, etc.

Store Memory
This command is necessary after any command to change the data rate, transceiver
address, or other radio setting that you wish to make permanent.

Display Modified Parameters
This command lists all parameter settings that are different from the factory default
settings. This will list changed parameters whether or not they have been stored with the
m> command. Note that issuing this command will cause the radio to lose link with the
base and will cause all remotes to lose link when issued to the base radio.
