Note that the MWV sentence appears in two forms: relative (R) and theoretical (T).
These two forms are enabled separately.
Also note that the XDR sentence appears in two forms: A and B. These two forms are
also enabled separately.
If either of fields <3> or <4> is a null field, then that field will remain unchanged from its
previous value.
The selections as to which sentences are enabled for transmission, and the rate at which
each sentence is transmitted, are stored in nonvolatile EEPROM memory within the
PB200 WeatherStation unit. On power up, these settings are copied from EEPROM into
a working copy in RAM memory. It is the working copy in RAM that determines the
behavior of the WeatherStation, with regard to the transmission of sentences.
Any changes to these settings using the $PAMTC,EN,<2>,<3>,<4> command only affect
the working copy in RAM. When power is lost, the changes to the working copy in
RAM will be lost.
The $PAMTC,EN,S command causes the contents of the current working copy in RAM
to be saved to EEPROM. The saved settings will then be restored to RAM each time
power is applied to the unit.
