Serial Interface (RS-422)
GNSS sentences
The LT-4100 system supports outputting of GNSS sentences encoded as NMEA 0183 via an RS-422 interface
from the LT-4100 system, as illustrated in Figure 103. The LT-4100 system has a built-in GNSS receiver in
the LT-4130 Antenna Unit.
Table 22 presents the supported GNSS sentences by the LT-4100 system. The configuration of the GNSS
sentences are illustrated and described in
on page 100.
IMPORTANT
: The GNSS receiver of the LT-4100 system is not certified according to IMO performance
standards for GNSS receivers. The LT-4100 system shall not be connected to equipment
where the GNSS receiver interface must be certified.
The GNSS sentences and decoding of these are further documented in
