PIONEERPOS G24-LC manual Sleep Mode when S24

Modem Configuration and Profile

Two modes exist:

•Idle mode: The G24-L has no data to send.

•Wakeup mode: The G24-L has data to send to the terminal.

After the G24-L changes the line edge to Wakeup mode, there will be a delay (the default is 30 ms) sent by the ats102 command before sending any data to the terminal (using RS232 protocol).

S24, Set Number of Seconds Delay Before G24-L Enters Sleep Mode

This command activates/disables the Sleep mode. The terminal sends ATS24=5, and if there are no radio and UART activities, the G24-L enters sleep mode in 5 seconds.

If terminal has some indication of the CTS pin activity, it can see:

•If +MSCTS=0 (default), the line changes its state periodically. (For more information refer to “+MSCTS, Enable/Disable CTS During Wakeup Period” on page 3-205.)

•If +MSCTS=1, the line is switched off at the moment of entering Sleep mode and stays off even if G24-L is awakened.
