At 0° The Merlin LT generates horizontal sections of points. This orientation can be used for proximity detection and
to assist dynamic positioning.
If the unit is repositioned with a different vertical angle, new lever arm values must be used. The pitch calibration
values must also be changed in your navigation package.
Use the four holes in the base plate to secure the Merlin LT directly to a mounting point on a vessel. Alternatively,
use the base plate to secure the Merlin LT to the mounting plate (see section 3.6.1).
A central point on the base plate marks a measurement datum point which you can use when surveying the lever
arm offset.
3.1.3 Connectors
There are four connectors on the Merlin LT unit, at the rear of the pod.
Each connector is uniquely matched to one of the supplied cables described in section 3.2.
When the cables are correctly and securely attached to the Merlin LT, the connections are watertight.
The connectors are supplied with protective caps which should be placed on the connector when the system is not
in use and cable are disconnected.
