Trawl systems
The SH80 interfaces a trawl system via Ethernet or on a serial line.
The serial interface uses either the NMEA 0183 standard, or
Simrad’s version of it. In the Simrad version of NMEA telegrams,
the Start Of Sentence delimiter
$
is replaced with
@
.
The following trawl systems are interfaced: ITI, FS900 and
FS3300.
Note
Other telegrams than trawl may be received from the ITI, since this
system may be used as a telegram router.
