3.6 Auxiliary equipment
The SD 570/SE 570 sonars require connection of a speed log and
a course gyro. An inaccurate log or gyro input will cause
inaccurate indication of the vessel and target movements.
Speed
log:
• Pulse log: 100, 200 or 400 pulses/nm.
• Serial line, standard NMEA 0183; RS232, RS422 or Current
loop.
Course gyr
o:
• 3-phase synchro signal, 20-220V L- L, 50/60/400 Hz.
Gear ratio 1:360, 1:180, 1:90, 1:36
• 3-phase stepper signal, 2 0-220V L- L.
Gear ratio 1:360, 1:180, 1:90, 1:36.
• Serial line, standard NMEA 0183; RS232, RS422 or Current
loop.
Echo
sounder:
In order to get a depth indication on the catch control page on the
sonar, one of the following Simrad echo sounders can be
connected:
• EQ50, EQ55, EQ100, ES60, ES380 series, ES500 (RS232 serial
line).
Trawl
system:
In order to get the trawl information on the sonar display, one of
the following Simrad trawl systems can be connected:
• FS 903 Trawl sonar system (RS232 serial line)
• FS 3300 Trawl sonar (RS232 serial line or 20 mA current loop)
• ITI Integrated trawl instrumentation (RS232 serial line)
