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>
The data shown for the external battery is estimated based on user entered parameters and the
power consumption of the receiver. The user should re-Enter the battery parameters after clearing
the receiver’s internal memory. Using receiver to power external devices such as radios can reduce
the effectiveness of this command.
$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.
$PASHR,POW
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.
$PASHR,POW,d1,d2,d3,f1*cc
