Responsibility - Simrad ITI TRAWL SYSTEM - SERIAL DATA COMMUNICATION REV A Instruction Manual

Simrad's philosophy is to let data from our ITI Trawl System be
available for integration with external equipment like chart
plotters, winch control systems etc. We are convinced that this will
increase the benefit of the product and lead to reduced integration
costs.
The quality of the transmission data depends on:
• sea condition
• depth
• temperature layers
• multipath
• most important - the noise level from the propeller because you
are receiving the signals from astern.
Compared to serial line data communication channel, the
hydroacoustic transmission channel is far more unstable with data
errors and intermittent interruption of the data transmission as a
result.
The appropriate filtering and display algorithm used by Simrad for
displaying the data on a CRT, might not be the optimum for
applications, which are using the data as part of input parameters
for controlling or regulating winches etc.
Simrad will therefore emphasise, to any one who are using the ITI
data, to design an application specific filtering and adding
"artificial intelligence" to the use of- and interpreting the data
received.
We will not involve ourselves in applications using our data but
any user will have access to the data from the ITI as described in
this manual. If special agreements aremade, Simradcan supplylog
files recorded during actual towings for test and simulation
purposes. Beyond that, Simrad have limited capacity to assistusers
of the ITI data in their application.
The use of the ITI data is the users responsibility and Simrad
disclaim responsibility for any consequences of using data from
the ITI.
