messages can be sent by internal NMEA servers to the NMEA 2000 network.
Each filter list has a switchable type: WHITE or BLACK. A message is passed
thru the WHITE filter if it contains a record matched with a message. And the reverse
for BLACK. In the factory settings, all filter lists are empty and are of BLACK type,
so all messages are passed through the filters.
3.1. Syntax of NMEA 0183 filters
NMEA 0183 filters contain 3-char NMEA 0183 sentence formatters separated
by a space character. According to the standard, an NMEA 0183 sentence starts with
a $ or ! symbol, followed by a two-character talker ID and a 3-char sentence
formatter. These elements are followed by data fields (after the comma).
The sentence is finished by a check sum after the * (asterisk) symbol. Gateway with
factory settings using «YD» talker ID, it can be changed on the «NMEA Settings»
page (see IV.2.2). The Device uses 3-char sentence formatters only for filtering.
The following sentences matches to GLL and VDM records (sentence formatters):
$GPGLL,4146.5894,N,07029.6952,W,173412.02,A*15
