Auxiliary equipment

The SP 270 sonar requires 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, 50/60/400 Hz.

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, RS-422 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 (RS-232

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 (RS-232 serial line)

• FS 3300 Trawl sonar (RS-232 serial line or 20 mA current

loop)

• ITI Integrated trawl instrumentation (RS-232 serial line)
