Figure 97: Installation Settings
5.9.1 Projector Orientation
The preferred orientation is with the projector facing forward. This configuration has been tested at
speeds up to 12 knots, with excellent results (hull and moon pool mounting). However, if the
installation requires the projector to face aft, this setting is used to renumber the beams to reflect
the aft orientation.
5.9.2 Projector Z Offset (m)
Sonic Control automatically senses which sonar is attached and will set the correct Projector Z
offset. If an alternative Projector Z offset is required (such as a system that is installed on an ROV),
the checkbox needs to be deselected in order to enter a new value for the Projector Z offset.
Using the standard R2Sonic mounting frame, the projector is mounted at a precise distance, relative
to the receive array, with a Z offset of 0.119m for the Sonic 2024 and 2022 and 0.045m for the Sonic
2026 being the default. If the projector is not mounted in the same vertical relationship to the
receive array, an offset can be entered here to compensate for that vertical offset. If the box is
checked, Sonic Control will automatically choose the correct Projector Z offset for the system. If a
non-standard offset is used, deselect the box to type in the correct Projector Z offset.
The default Z offset value is 0.119m (0.045m for the Sonic 2026); this is the physical distance
(vertical) between the receive array ceramic face and the acoustic centre of the projector array), as
used with the standard R2Sonic mounting frame (with 35mm projector standoffs for the Sonic
2024/2022).
Do not change
this value unless the projector is mounted with a different vertical offset
relative to the receive array. Please contact R2Sonic for further guidance on mounting the projector
with a different vertical offset.
5.9.3 Head Tilt
If the sonar head is physically tilted to port or starboard, the tilt angle is entered here to rotate the
wedge and depth gates. The head tilt limits are ±45°. If the head needs to be tilted more than 45°,
please contact
R2Support@R2Sonic.com for instructions.
