pwr vcct vv.v t

Controls the supply voltage below which the CTM-200 gateway will automatically go into standby mode.

vv.v = 6.0 to 25.5	threshold supply voltage at which the gateway will go into shutdown (default 9.0, typical for 12V battery operation)
t = 10 to 255	duration of time in seconds that the supply voltage is below the threshold voltage before gateway enters shutdown (default 10)

Examples:

Set the threshold to 20.0 volts with 10 seconds delay – this may be appropriate for a 24 volt battery :
cmd pwr vcct 20.0 10
