6BCommand Reference
cmd pwrsdwn 1 3600
this will cause the modem to power down when the standby signal (ignition) has
been inactive for 1 hour. The modem will power back up when the standby signal becomes active with no
delay.
cmd pwrsdwn
returns the current settings of enable/disable and delay time
A cmd save is required for this command to take effect.

pwrvcct vv.v t
Controls the supply voltage below which the modem will automatically go into shutdown
mode (blinking
power LED). This command is useful for battery powered applications where the modem can be put into a
very low power consumption mode (shutdown mode) to prevent draining the battery.
vv.v = 9.0 to 25.5
The threshold supply voltage at which
the modem will go into shutdown (default =
9.0V, typical for 12V battery operation)
t = 10 to 255
the time in seconds after which the modem will go into shutdown once the supply voltage
has gone below the threshold voltage. (default = 10)
Note that this timeout applies for powering the modem back up as well.
The current setting can be queried by entering the
pwrvcct
command without parameters.
Examples:
1. Set the threshold to 20.0 volts with 10 seconds delay – this may be appropriate for a 24 volt battery
cmd pwrvcct 20.0 10
OK
2. Query the current voltage and time settings
cmd pwrvcct
cmd pwrvcct 9.0 10
OK
