POW: Battery Parameters
$PASHS,POW,d1,d2,f1
This command sets the parameters associated with the external battery. The query
and response uses the entered parameters to compute the approximate amount
of remaining battery time. Table 6.37 defines the parameters.
Example
Enter the following command to set the battery capacity to 1000 mAh, the battery
capacity percent to 100%, and the battery voltage to 12.0 VDC.
$PASHS,POW,1000,100,12.0
The data for the external battery is estimated based on user entered parameters and the power
consumption of the DG16. Re-enter the battery parameters after clearing the DG16’s internal
memory, or connecting to a different battery. Using the Dg16 to power external devices such as a
radio can reduce the effectiveness of this command.
$PASHQ,POW,[c1]
The query command requests current available battery power data, where c1 is the
optional port designator for the output of the response. If a port is not specified, the
receiver sends the response to the current port.
$PASHR,POW,d1,d2,f3
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.
