BAM sentences
The LT-4200 system supports connection to an external Central Alert Management (CAM) system via an RS-
422 interface from the LT-4200 system, as illustrated in Figure 91. The CAM system can receive BAM
information (e.g. warning and cautions) from the bridge equipment and centralize and present this
information to the user, which can be acknowledged to the BAM equipment (here the LT-4200 system).
Table 21 presents the supported BAM sentences by the LT-4200 system. The configuration of the BAM
sentences is illustrated and described in
on page 99.
NOTE
:
The encoding of BAM sentences is defined in IEC 61162-1 (Edition 5.0, 2016-08), the
encoding is similar to NMEA 0183.
The BAM sentences and decoding of these are further documented in
on page 114.
