the barometric pressure altimeter setting provided in fields 1 and 3 of the
transmitted $WIMDA sentence.
Fields <3> and<4> of the $PAMTC,ALT,SET command define how to use the
altitude setting provided in field <2>.
All of the parameters of the $PAMTC,ALT,SET command are stored in
nonvolatile EEPROM memory within the PB200, and so remain programmed
even after cycling power. If any of the fields <2>, <3>, or <4> are null fields, the
corresponding stored value will remain unchanged.
The $PAMTC,ALT,Q command is used to query the values of the parameters
currently programmed into the PB200. The unit will reply with
$PAMTR,ALT,a,b,c
where a, b, and c correspond to fields <2>, <3>, and <4>, respectively, in the
$PAMTC,ALT,SET command.
This sentence performs the same function as the transmitted proprietary NMEA
2000® PGN 126720-48.
Field <2> corresponds to the NMEA 2000® transmitted PGN 129538, field 9, and
proprietary PGN 126720-48, field 5.
Field <3> corresponds to the NMEA 2000® transmitted PGN 129538, field 10,
and proprietary PGN 126720-48, field 6.
Field <4> corresponds to the NMEA 2000® transmitted proprietary PGN
126720-48, field 7.
