Trawl Interface
A Simrad ITI (Integrated Trawl Instrumentation) system can be
connected to a RS-232 port at the rear of the EQ60 computer.
Communication with the ITI system is based on NMEA
telegrams. The EQ60 may transmit depth telegrams to the ITI.
Useful input telegrams from the ITI are automatically
interpreted.
• The $IIDBS telegram contains the headrope depth.
• The @IIHFB telegram contains the vertical distance between
the headrope and the footrope.
Trawl opening
A fixed headrope-to-footrope distance can be manually entered.
This is used for trawl sensor systems not measuring the trawl
opening, or when the measured headrope-to-footrope distance is
unreliable. Enable for manual setting in the check box, and enter
the desired opening.
Data input
The most recent input telegrams are displayed in a list. This
function is useful during installation and trouble shooting.
Clear - This button clears the list of input telegrams.
Other options
RS-232 - This button activates the RS-232 Setup dialogue box
for communication port, baud rate etc.
