12.2 Interface design specification (IDS)
For the display of the meteorological parameters the NMEA
0183 message strings as mentioned below are required by
the indicator. From the received message string containing the
a.m. parameters the indicator electronic filters, converts and
displays the required information. Regarding the sequence
of the messages in a common string there is no explicit re-
quirement. As the indicator is evaluating the three-letter-code
with sentence formatters only the performance of the talker
identifier is not considered.
