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.
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 WIT2420 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 WIT2420 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.
