•
Enable the serial interface's Ring Indicator (RI_N) signal.
Data on the Serial interface
During low power mode, serial communications is limited to short periods, while G24 is paging
the network. When the serial interface is active, data can be exchanged between the application
and the G24.
the G24 will not return to low power mode until the serial interface transmission is completed and
all the data is processed.
Only when the serial interface transfer is completed and the data is processed, G24 will return to
low power mode automatically, according to the ATS24 settings (see

Permanent termination of Low Power Mode

The G24 low power mode is enabled and disabled by the ATS24 command.
To permanently terminate the G24 low power mode, the ATS24 = 0 command must be used.
Setting ATS24 = 0 disables the currently active low power mode and switches G24 to Idle mode.
G24 will not return to low power mode until an ATS24 > 0 commands is set again.
This command can be sent only when the serial interface is active.
In case the serial interface is disabled, it must first be activated before sending this command. To
reactivate the serial interface, a temporary termination of the low power mode is required, as
described in
Following the temporary low power mode termination, the serial interface will activate and the
ATS24 = 0 command can be received by G24.
