Commands
POW: Battery Parameters
$PASHS,POW,d1,d2,f3
The POW command allows you to enter parameters associated with the external
battery. The query and response will use those parameters to compute the
approximate amount of available time left on the battery.
Example: Set the POW parameters of a 12 volt battery with a capacity of 5000 mAh
that is 100% charged.
$PASHS,POW,5000,100,12.0 <enter>
$PASHQ,POW,c
The POW query command requests current available battery power data, where c is
the optional port to which the response will be sent. For external battery, the available
battery power displayed in the response is computed from the battery parameters
entered and the amount of time the receiver has been on after they were entered. For
internal battery, it is read from the smart battery, no $PASHS,POW is required in that
case.
$PASHR,POW,d1,d2,d3,f4*cc <enter>
The data shown for the external battery is estimated based on user entered parameters. The user
should re-enter the battery parameters after clearing the receiver’s internal memory. The data
displayed for the internal battery is the direct reading from the smart battery.
