8.3 Course gyro connection
Overview
The SP60 sonar can read the course information from an RS-232
serial line. In case where only a 3-phase synchro or stepper signal
is available, an optional Gyro Interface Unit must be used for
converting these signals to RS-232 serial line format.
→
More information about the Gyro Interface Unit can be found on
page 6.
Gyro with RS-232 serial line output
The course data on the RS-232 serial line must be on a standard
NMEA 0183 telegram format. The telegram can contain both the
speed and the course data.
→
Refer to the telegram format description on page 155.
Refer to the cable connection drawing for termination of the serial
line data in the Sonar Interface Unit.

Refer to the drawing on page 176.
For connection to the course gyro, refer to the applicable gyro
documentation.
Gyro with 3-phase synchro or stepper output
If only a 3-phase synchro or stepper signal is available, an optional
gyro interface unit must be used to convert these signals to RS-232
serial line format. An
LR40 Digital Gyro Repeater may be used for
interfacing the following signals:
•
3-phase synchro signal, 20-115V L-L, 50/60/400 Hz, gear ratio
1:360 or 1:180
•
3-phase stepper signal, 20-115V L-L, gear ratio 1:360 or 1:180
The LR40 Digital Gyro Repeater can be delivered from Simrad on
part number 298-078535.

For connection to the LR40 Digital Gyro Repeater, refer to the
LR40 Instruction Manual.
Refer to the cable connection drawing for termination of the serial
line data in the Sonar Interface Unit.
