8.1 String Definition
The strings follow the standards IEC61162-1 and NMEA0183; some
general knowledge of these standards is assumed. BSL-336 uses
strings defined in
IEC PAS 61162-102 Extra requirements for the
Voyage Data Recorder, Pre-standard First edition 2003-12.
AutroSafe transmits the following basic strings to the VDR:
Interfacing Voyage Data Recorder Systems, AutroSafe Interactive Fire-Alarm System, 116-P-BSL336/EE, RevA 2007-01-25,

8.1.2 Equipment Indicators/numbers
The various sentences contain fields that describe “division indicator”
and “door/detector number”. These may contain fire zone, central
number, deck number, loop number etc.
The BSL-336 is a simple protocol converter that does not contain
topology information. It does not tell which loop each detector is
connected to. AutroSafe refers to the hardware using a unique UnitId,
namely a two-letter code followed by a sequence number.
