Specialities of certain NMEA messages
•
The NMEA message for indication of a rudder angle (NMEA RSA message) can
distinguish between left and right rudder.
Default: Single Rudder or Synchronous Rudder
•
The NMEA message for indication of rotation speed can distinguish between engine
rotation speed (RPM) and shaft rotation speed (Engine/Shaft).
Default: Shaft rotation speed
•
The NMEA message for indication of depth information can handle offsets which
comprise the difference from sensor (Transducer) to keel.
Default: Offset 0 – Depth relative to Transducer
4. Operation
4.1 Displays
Scale example: Rudder angle ± 80°, standing display
The read out distance for SERANA-Q 96 is 1.7 m
The read out distance for SERANA-Q 144 is 2.2 m
4.2 Pointer
When powered off, the pointer must be located on the lower left zero point.
For hanging indicators, for example some rudder angle indicators, the zero point is top left.
