|Fly-By-Wire Steering: a steering wheel that
holds the heading
Steering Wheel or the Joystick determines the rate of turn of the boat, not
the rudder angle.
wheel or Joystick centered, the heading is held. The artificial
boat stability is a main aspect of Fly-By-Wire steering. The Sonic
Heading Gyro is the heart of the system: a gyro compass which is produced by TECNAUTIC since
1992. The Autopilot positions the rudder and activates the thrusters as
needed, so as to achieve the
requested turn rate of the boat, determined by the electronic wheel or
Installation of a second helm becomes simple and inexpensive. Up to eight
fixed or portable
Fly-By-Wire steering wheels, throttle stations or Joysticks can be connected to the network at a fraction of
the cost of a mechanical or hydraulic helm.
The rudder will be driven by an Autopilot Drive or by Servo Valves.
Almost any sort of Drive or Valves can be connected to the Autopilot
Computer. Rudder motion will be smooth and accurate.
Forget complicated shift, throttle and
wheel combinations in
Simply move the Joystick in the direction you want your boat to move.
||Cockpit Displays include analog color
In addition to the digital LCD, an analog
LED-pointer is included around the face of each cockpit display. Depending on the selected
function, the analog LED pointer may work as a compass needle, wind angle indicator,
amplified boat speed indicator, rudder angle, depth or trim flap indicator etc.
||Night time viewing and group
wise illumination control
The analog LED pointer can be dimmed
continuously down to zero and the LCD can be back lit for night time viewing.
When several displays are located in a group, e.g. in a forward cockpit, they can be
assigned the same group number. Adjusting the brightness of one of them will make the
others follow to the same brightness level.
A total of 15 groups can be created, with an unlimited number of displays in each group.
Tecnautic Displays offer more
flexibility and more safety
Each cockpit display can show all
available data of the system, e.g. compass, log, wind, depth or GPS data
etc. Data originating from Displays, Steering Wheels, Joysticks or Throttle
distributed in the system over the network cable (CAN bus).
In addition to the bus connection, every
display unit can be individually connected to one analog and one digital
sensor. For example, a Sonic Heading Gyro can be connected to the "analog"
input of a display and the NMEA in- and output of a Compass Sensor can be connected to the "digital"
input/output of a display unit.
The sensor input can be unrelated
to the displayed function on that unit. A Sonic Heading Gyro for example can be connected
to a "Depth Display" or a Magnetic Compass Sensor can be connected to an
"Autopilot Display", if this makes the installation easier. As you realize
already, there is no "Depth Display" or "Compass Display" etc., they
are all technically identical, only the printing on the bezel and the number of key buttons
may be different.
The size of the displays is 114 x 132 x 17 mm (4.5 x 5.2 x 0.67 in.). They
are flush mounted. A small hole in the center is required for installation
of the cables.
A display unit that receives signals from a directly connected analog sensor or NMEA-data
from a directly connected digital sensor, will transmit these data at high speed to all other displays, steering wheels and the autopilot. A display
unit receiving data over the CAN-bus can output them via its digital NMEA-output, if desired.
There is no central processor in the
system. Instead there is distributed functionality.
The JUMBO displays offer 40 mm digit height (1.5 inches). They are available in
fluorescent red or yellow.
They can be set to display any parameter in the system. With two water tight
network connectors at the back side, daisy chaining of multiple units becomes easy.
The integrated illumination can be adjusted remotely from
a cockpit display.
The price of the TECNAUTIC JUMBO displays is unmatched.
Silent and power saving
Two Autopilot Drive-Boxes can be installed to drive two pumps, either alternating or parallel, in
an augmentation mode, where the second pump starts only when a higher rudder
speed is needed.
In Docking Mode with individually steered rudders or stern or pod
drives, the Drive-Boxes will command individual steering angles.
On larger vessels, where constant hydraulic pressure
is available, the same Autopilot can drive electric servo valves or
proportional valves instead of the rudder motor.
One FADEC-Box for each engine controls the throttle and shift and -
depending on the model - the Trolling Valve and engine start circuit. Clutch
engagement is always gentle, with no rocking. With a trolling valve
installed, clutch pressure is increased steadily, not abruptly.
Bus Cable: cannot be disturbed
Fly-By-Wire steering, instruments, autopilot
and engine controls are
connected with identical cable. The cable has two wire pairs, one for data and one for the
supply. If custom wiring is selected, branching of the bus cable is accomplished with
RJ-45 connectors. These can be installed with a simple crimp tool. Standard cables
are shipped with connectors already installed.
The TECNAUTIC network is based on a time
driven CAN© protocol. It has a so called Multi Master Architecture and it
guarantees data transmission within a defined time. Most other protocols slow down
when an increasing number of nodes (equipment pieces) is connected to the
bus. Not so the Tecnautic CAN bus.
Transmission speed is 125 kbit/s. The distance between any two nodes on the bus may be up
to 200 m.
