This driver uses an old implementation of crane functionality where some calculations are done in the driver. It is recommended to use Object linking in combination with a rotation sensor.
For more information about object linking, use this document in the Qinsy Knowledge Base: 'How-to Object Linking'.
The Crane Tool VanDerLeun Driver decodes #QATT, #QXYZ and / or #QD messages from the Van Der Leun dredging computer that is mounted on board cranes used for dredging.
The dredging computer will deliver relative position, attitude and heading of one or more boom segments and the grab.
Qinsy will decode the position information as USBL, so it is not a real USBL system.
The driver has a user-interface for assigning the VRU systems to the slot information, this is not supported in Database Setup for these systems.
Two versions of the driver are available: a Serial version and a Network version (UDP).
The internal workings of the drivers are the same except for the data reception.
