MET,PAR: Setting the Meteorological Unit
Function
This command is used to define all the parameters needed to
communicate with the meteorological unit.
Following the execution of this command, and then that of
$PASHS,OUT,x,MET,ON, the receiver will regularly query the
meteorological unit by sending the trigger string every x
seconds of query interval.
Command Format
Syntax
$PASHS,MET,PAR,c1,s2,s3,d4[*cc]
Parameters
Comments
• This command overwrites all the settings previously
performed with the following commands:
– $PASHS,MET,INIT
– $PASHS,MET,INTVL
– $PASHS,MET,CMD
• In fact, the $PASHS,MET,PAR command is used for the
same purpose as, and is more convenient than, the above
three commands, which are maintained only for the sake
of compatibility with the Ashtech iCGRS reference station.
