Required inputs
The Simrad SP60 sonar system requires input from both a speed
log and a course gyro. Inaccurate data from either of these
instruments will result in an incorrect indication of vessel and
target movement.
Speed log
The speed log parameters are:
•
Pulse log: 200 pulses / nm.
•
Serial line, standard NMEA 0183, RS-232
→
Also refer to (D)GPS below.
Course gyro
The course gyro parameters are:
•
Serial line, standard NMEA 0183, RS-232
An optional gyro interface box for converting the following
synchro and stepping gyro signals can be ordered from Simrad:
•
3-phase synchro signal, 20 to 150 V L-L, 50/60/400 Hz, gear
ration 1:360 or 1:180
•
3-phase stepper signal, 20 to 150 V L-L, gear ration 1:360 or
1:180
→
Refer to page 5 for the Simrad order number.
Additional inputs
In addition to the pulse log input described above, the SP60 sonar
provides a total of seven RS-232 serial lines. Since one is used to
interface the course gyro, the remaining six serial lines may be
used for:
•
Differential Global Positioning System - (D)GPS
•
Echo sounder
•
Purse seine system
•
Trawl system
•
Current meter system
•
Radio buoy system
Differential Global Positioning System - (D)GPS
A (D)GPS may be interfaced with the Simrad SP60 sonar to
establish the vessel’s position and provide cursor and marker
latitude and longitude.
