8.6 Trawl system connection
The SH80 sonar can read the trawl data from a Simrad FS Trawl
sonar or ITI (Integrated Trawl Instrumentation) system. The
communication is achieved using a RS-232 serial line.
When connecting the FS Trawl sonar to the SH80 Sonar Interface
Unit the trawl depth will automatically be shown in accordance
with the surface, targets and bottom in the vertical modes on the
sonar.
When the ITI trawl system is connected to the SH80 sonar, the
information exchanged between the ITI and sonar is:
ITI to sonar:
•
Trawl position relative to vessel
•
Depth of trawl below surface
•
Trawl headrope to footrope distance
•
Trawl door spread
•
Trawl filling
•
Water temperature at trawl
Sonar to ITI:
•
Position of target or marker
Refer to the cable connection drawing for termination of the serial
line data in the Sonar Interface Unit.

Refer to the drawing on page 159.
For connection to the trawl system, refer to the RS-232 output in
the applicable trawl system documentation.
