The MADBrain solution is fully compatible: NMEA2000. This standard of the nautical industry ensures a strong hardware compatibility, controlled costs and an easy installation (the connectivity is also standard).
The following sensors are available in NMEA2000: GPS, sounder, speedo, barometer, compass, inertial unit (see below)...
Wind measurement
For wind measurement, we require one of the following sensors (NMEA0183 compatible)
B&G Aerial
Aerial CarboWind NKE
These models are connected to the high frequency CANBus via a MADMast box.
The mast acquisition module: MAD Mast
The Mad Mast acquisition module is a measurement unit dedicated to the acquisition of signals from mast-related sensors. It has an opto-coupled, lightning and ESD protected NMEA0183 input, an ESD protected analogue input for mast angle measurement and a 12V isolated power supply which is also ESD and lightning protected.
MAD Mast interface inputs/outputs
1 x optocoupled NMEA0183 input (NKE and B&G compatible)
1 x analogue input
1 x voltage source
Dimensions excluding connectors: Height 65 mm, width 65 mm, depth: 41 mm
Power supply via CAN bus: 8-36V
The course and movements of the boat
Madintec imposes an inertial unit that will provide the dynamics of the yacht. The MADSensor XD is a high-end inertial unit with two triple band GPS antennas.
This unit provides the following information:
Other sensors
In the case of an installation on a boat already equipped with non-compatible sensors, e.g. a NKE installation, it is possible to use a converter such as the MADInterfaceAnalog.
The MAD Interface Analog acquisition module
The Mad Interface Analog is an analogue data acquisition module that communicates with the bravo control unit and Madintec products via the proprietary 500kbps CAN bus.
It is used to convert signals from analogue sensors (e.g. rudder angle, actuator shaft position...) or any other voltage level 0-5V, 0-10V or 4-20mA.
It samples at 200Hz and its accuracy is of the order of one ten-thousandth
In addition, it has 3 voltage sources to supply external sensors
All three voltage sources are short-circuit proof. The MAD Interface Analog can be configured using the CAN Diagnostic Tool software.
MAD Analog Interface Inputs/Outputs
8 x Analog inputs 0-5V, 0-10V 16bits single ended
2 x Pulse inputs (referred to GND or floating inputs)
1 Can bus (for proprietary Bravo/Madintec bus)
1 x status Led (green in normal operation, flashing red or permanent in case of a detected fault)
All inputs are protected up to 30V DC and against the most common electrostatic discharges.
No-load consumption
Dimensions excluding connectors
Height: 66 mm
width: 119 mm
depth: 61 mm
Power supply: Via CAN bus 8-36V.
