NOTE: In order to preserve this setting after reset or power-up, the new setting has to be
stored to flash memory by using the
$PFST,STORE command.
5.2.4 DATUM – Set Local Coordinate System
Selects the local coordinate system. After this command, the PCM3292 will return positions
in the selected coordinate system.
$PFST,DATUM,<datum_id>
<datum_id> Coordinate system id. See appendix for supported DATUM id’s.
NOTE: In order to preserve this setting after reset or power-up, the new setting has to be
stored to flash memory by using the
$PFST,STORE command.
5.2.5 FIXRATE – Set Fixrate
Defines how often PCM3292 should acquire navigation fix and thus output
the NMEA messages.
$PFST,FIXRATE,<fixrate>
<fixrate> Number of seconds to between navigation fixes
NOTE: In order to preserve this setting after reset or power-up, the new setting has to be
stored to flash memory by using the
$PFST,STORE command.
5.2.6 SYNCMODE – Synchronous NMEA Output Mode
Enables or disables the synchronous NMEA output mode. In the synchronous output mode,
all the enabled NMEA navigation messages are outputted approx. once per second,
regardless of the availability of a valid navigation fix. The synchronous mode is enabled by
default.
$PFST,SYNCMODE,<mode>
<mode> Set synchronous mode on or off, 0 = off, 1 = on (default).
NOTE: In order to preserve this setting after reset or power-up, the new setting has to be
stored to flash memory by using the
$PFST,STORE command.
5.2.7 STORE – Store Current Parameter Set
Stores the current parameter set in PCM3292’s flash memory. These parameters include
those that are defined by the commands, ALTAID, AUTOSTART, CONF, CABLEDEL,
DATUM, FIXRATE, NMEA, PPSMODE, PULSEPOL, PULSELEN, SETLIMIT,
SURVEYLEN, and SYNCMODE.
$PFST,STORE
NOTE: Navigation has to be stopped before giving this command.
NOTE: PCM3292 doesn’t store configuration parameters in flash memory, and thus
this command doesn’t have any effects on the PCM3292 modules. For PCM3292, the
preferred way is to set parameters each time, when the module is reset or switched on.
