(But it's all in a Windows unpacker and I don't do windows.)
The only extra information when unpacked refers to the new position
averaging:
____________________________________
A GPS 18x user can now enable or disable internal position averaging via
the PGRMC1 input NMEA sentence.
Position averaging can be enabled by transmitting the following command
string the to GPS18x using a terminal program:
$PGRMC1,*,*,2,*,*,*,*,*,*,*,*,*,*,*<CR><LF>
Note: * indicates any appropriate numerical value as indicated by 18x
documentation.
Position averaging can be disabled by transmitting the following command
string the to GPS18x using a terminal program:
$PGRMC1,*,*,1,*,*,*,*,*,*,*,*,*,*,*<CR><LF>
Note: * indicates any appropriate numerical value as indicated by 18x
documentation.
