200 – PowerManagement
This command sets the power mode to Full Power, Adaptive Trickle Power,
or Push-to-Fix mode. The table below contains the values for the following
example to set the receiver to Adaptive Trickle Power mode:
$PLSC,200,2,200,3000,300000,30000*0D

Must be a multiple of 100 (if not, it is
rounded up to the nearest multiple of 100).
Set this to 0 when Mode = 3.
Must be an integer value 1000 and
10000. Set this to 0 when Mode = 3.
When Adaptive Trickle Power is enabled,
this is the maximum allowable time from
the start of a power cycle to the time a valid
position fi x is obtained. If no fi x is obtained
in this time, the receiver is deactivated
for up to MaxOffTime, and a hot start is
commanded when the receiver reactivates.
The integer must be in multiples of
1000ms. There is no upper limit.
The longest period (in mS) for which
the receiver deavtivates due to the
MaxAcqTime timeout. The actual
deactivated period may be less if the
user-specifi ed duty cycle (OnTime /
LpInterval) can be maintained.
The receiver automatically awakens every
Push-to-Fix period to obtain a position fi x,
collect ephemeris (if needed), and calibrate
the real-time clock (RTC) (if needed).
