7 CONNECTING AUXILIARY EQUIPMENT
7.1 General
It is not necessary to make the connection of the auxiliary
equipment before the start- up procedure is finished, and this
equipment may therefore be connected later. Anyhow, do not
connect the plugs for the auxiliary equipment to the Sonar
Control Unit before mentioned in a later chapter.
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 gyro:
· 3- phase synchro signal, 20- 220V L- L, 50/60/400Hz.
· Gear ratio 1:360, 1:180, 1:90, 1:36.
· 3- phase stepper signal, 20- 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 Trawl sonar (RS 232 serial line or 20mA current loop).
· ITI Integrated Trawl Instrumentation (RS232 serial line).
