1 OVERVIEW
Thank you for purchasing the nke Multigraphic.
The Multigraphic features a 5.7 inch colour screen. A transflective polarizer
enhances daylight reading and integrated LED backlighting ensures clear readability
at night. The backlight intensity can be automatically adjusted or user adjusted.
The Multigraphic is a multifunction device allowing:
•Control of the nke Gyropilot2 or Pilote HR
•Display of data from the sensors connected to the Topline bus in digital,
analogue or graphic formats and access to setup parameters and alarms.
•Display and processing of A.I.S. target data in a 12 mile range for collision
avoidance, providing there is an A.I.S. receiver connected.
•Interface to NMEA 183 devices to provide relevant data to the Topline bus.
2 OPERATION
The Multigraphic offers 10 buttons to control the display, access the menus and
control the autopilot.

Using the Remote Display transmitter
The Remote Display Transmitter can be used to display the different pages
constructed, to access the menu, etc. The operation is the same as the Multigraphic
keyboard.
To select the Multigraphic, press and hold the page button on the transmitter for
about 5 seconds. The radio receiver emits a long beep indicating the validation of the
display selection mode. Then press the right or left arrow to display a yellow frame on
the screen, press OK to select it. You can then use the Remote Display in the same
way as the Multigraphic keyboard.

2.4.1 Page 4+4
This page toggles between 2 groups of 4 functions. It can also be used to display
data coming from racing software via the NMEA input once it has been set up (refer
to “NMEA settings”). For example, software such as ADRENA feeds the system with
8 functions depending on the race course legs and this information can be read on
these pages. They can be displayed on any Multigraphic in the Topline network. The
8 available channels are named DYN 1 to DYN8.

2.5 Multigraphic operation with the Gyropilot 2 processor
Gyropilot is an automatic pilot designed to steer the boat. It is intended to assist the
helmsman and should never be used without state of the art navigation equipment
handled by a qualified navigator.
Once the pilot has been engaged by the helmsman the Gyropilot 2 processor will
save the current value of the relevant channel: ie. magnetic heading, wind angle or
GPS course. This value becomes the reference for course to steer.
From that point the processor uses the data coming from the sensors to control the
rudder using the following criteria:
- the error to the course to steer, from data coming in from the compass (compass
mode) or the wind unit (wind mode).
- the boat motion delivered by the gyrometer. This sensor measures boat rotation
due to the action of the rudder, the wind or the waves.
The correction value is linked to:
The error from the course to steer,
The gain value,
The boat speed (the correction factor is opposite to the boat speed. i.e. with
a very low boat speed the correction factor is high, and with no boat speed the
Gyropilot will not perform).
Never leave the helm unattended. The helmsman has responsibility for keeping
an efficient watch and to be ready to act in case of any event affecting the route of the
boat. He must be ready to disengage the pilot and control the helm at any time.

go directly to the Pilot Mode menu.
Press once to disengage the pilot and take the helm back under
manual control.

Press and hold for automatic tack from port tack or gybe from starboard
tack.
Press the up and down arrows to adjust the gain from 1 to 9 and press
OK to confirm.

2.5.3 Pilot Modes
Select the pilot mode as follow:
Press and hold this key (>3s) to go directly to the Pilot Mode
menu. This shortcut is available from any page
True Wind mode
This mode requires a speed sensor, a compass sensor, a wind sensor and the
software add-on « true wind ». Once this mode has been selected the pilot steers the
boat to a set true wind angle as calculated by the processor.
The true wind mode is particularly well adapted to downwind conditions in waves.
These are the conditions where the nke pilot demonstrates its true capability. If
apparent wind was used you would get the following issues:
-The boat sails down the wave and apparent wind speed decreases, the apparent
wind angle decreases: it is a header, the pilot bears away to maintain the wind
angle it is set to steer to.
-The boat sails up the wave and apparent wind speed increases, the apparent
wind angle increases: it is a lift, the pilot luffs up to maintain the wind angle it is
set to steer to.
As a result, in waves the apparent wind mode is not efficient and it is better to select
the compass mode to keep a straight course.
With true wind mode the pilot steers the boat on a straight course keeping the
optimum wind angle in the waves. The wind angle to steer is not affected by boat
speed variations. While sailing solo it is very efficient to leave the pilot to steer the
boat and focus on sails trim (just watch power consumption).

True wind software add-on
A code is required to activate the true wind mode function. Please contact your nke
dealer to get this code. The code number is linked to each Gyropilot 2 processor,
your dealer will need your processor’s serial number to issue the code for the
software add-on. This serial number can be found on a label on the processor itself
or in the true wind menu of the Multigraphic.
Activation of the true wind add-on:
The hexadecimal code is entered with the virtual keyboard. Once the function is
activated the little padlock symbol will turn open and green.
Apparent wind mode
This mode requires a speed sensor, a compass sensor and a wind sensor.
With the apparent wind mode the pilot uses data from the mast head unit through
the Topline bus to steer the boat on a set apparent wind angle. This mode is mainly
used while sailing upwind.
Compass mode
This mode requires a speed sensor and a compass sensor.
With the compass mode the pilot uses the compass heading data from the Topline
bus to steer the boat on a set heading.
Rudder mode
The rudder mode allows the rudder to be set at a fixed angle. The value can be
between – 35° and + 35° to the mid-ship position.

20 50_Afficheur_Multigraphic_um_UK_27
Autopilot in GPS mode
In GPS mode the Gyropilot steers the boat to a route provided by the GPS or the
navigation software connected to the NMEA input of your Topline system.
2.5.4 Pilot settings
Select the pilot’s settings page:
Rudder coefficient
Principle: the Gyropilot processor automatically adjusts the value of the rudder
angle to apply which is proportionally opposite to the boat speed. The faster the boat
sails the lower the rudder angle.
This can be tuned to achieve best results by modifying the rudder coefficient between
the 1 and 53 value range. The higher the value is, the greater the rudder angle
proportionally to boat speed. The default setting is 6, which is valid for a 30 footer.
Examples: a Figaro 2 or similar boat will require this factor to be 15, for a 60 footer it
can be 20 and a multihull will be better with 30.
Note: if there is no boat speed data on the Topline bus, the Gyropilot uses SOG
(Speed Over Ground) if available.
A good way to learn the effect of this value setting is to enter an extreme
value, i.e. 50, and note the different behaviour of the boat before and after
the setting change.
