Serial Port Shutdown Mode
The modem could be configured to shut down the serial link interface while there is no traffic on the
serial link channel by the following AT command:
•
Enabling Serial Port Shutdown Mode
AT+KGPIOCFG=7,0,2
//set GPIO7 as an output
AT+KGPIO=7,1
//set GPIO7 output high
•
Disabling Serial Port Shutdown Mode
AT+KGPIOCFG=7,0,2
//set GPIO7 as an output
AT+KGPIO=7,0
//set GPIO7 output low
For more information about AT commands applicable to the GL7500, please refer to document [3]
AirPrime HL7588 AT Commands Interface Guide; for more information about AT commands
applicable to the GL7600, refer to the commands marked as supported by HL7692 in document [4]
AirPrime HL76xx AT Commands Interface Guide
The Serial Port Shutdown Mode will be immediately activated within 30 seconds after the AT
command set. To wake the modem up from this mode, just simply send AT command to the modem.

Power Consumption Values
These consumption values were obtained by performing measurements on samples at a temperature
of 25°C with the assumption of a 50
Ω
RF output.
Three DC inputs (DCIN) were used to measure the consumption: VinMIN (4.75V), VinTYP (12V) and
VinMAX (32V). Both the average current and maximum current peaks were also measured.
Note that power consumption performance is also software related.
Note:
TX = the current peak is the RF transmission burst (Tx burst)
RX = the current peak is the RF reception burst (Rx burst)
