Gateway with factory settings using «YD» talker ID, it can be changed
on the “NMEA Settings” page (see X.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
!AIVDM,1,1,,B,ENk`smq71h@@@@@@@@@@@@@@@@@=MeR6<7rpP00003v
f400,4*5F
Example of correct NMEA 0183 filter text:
GLL VDM DPT
2. Syntax of NMEA 2000 (RAW protocol) filters
You should be familiar with the NMEA 2000 Standard (can be purchased
from National Marine Electronics Association,
www.nmea.org
) to operate with
NMEA 2000 filters.
These filters actually contain pairs of 29-bit message identifiers and a mask.
The identifier is compared by processing the NMEA 2000 message identifier
and the second value (mask) defines the comparison concerning which bits
are significant. The identifier contains a PGN (Parameter Group Number, described
in NMEA 2000 Standard) and a source device address. You can use decimal
and hexadecimal numbers (which start with a 0x prefix).
To simplify defining filters, it is also allowed to set filters using PGN only. The filter
string contains records separated by comma. Records contain an identifier and mask
separated by space, or a PGN number.
