Wire thickness
Important! Use the following tables to determine wire thickness from the
battery to the servo unit, from the servo unit to the pumpset, from the servo
unit to the bypass valve.
Connections to the NX2 instruments/server/transducers is made with Silva
Nexus cable (shielded).
If rudder angle transmitter cable needs to be extended this can be done
with standard 0,25 mm² cable.

Installation of the Linear Rudder Angle Transmitter
Included your linear rudder angle transmitter there are a number of resistors. Find out the length of the tiller
arm (page 8-52 in the NX2 Autopilot manual) or maximum rudder angle.
Each plastic bag containing the resistors is also marked with tiller arm length and max rudder angle. Please
choose the resistor that suits your boat.
If your steering system has a mechanical stop which not makes your linear pumpset able to reach its
maximum length, then you choose resistors after the length of the tiller arm and set the max rudder angle
manually in the Autopilot instrument (see page 26 in the Autopilot instrument manual).
When you know which resistors to use, you solder one resistor on the red cable, and one on the black cable
(see picture). After you have soldered the risistors isolate the wires carefully.
How to get correct value of the resistor to the linear rudder angle transmiter
In the table below you will find: which length of the tiller arm you can use, which maximum rudder angle you
will get, which exact value of the resistor it will be with the specific rudder angle, which value of the resistor
that is a standard resistor, which maximum rudder angle you will get if using a standard resistor value.
The rudder angle transducers impedance is 11,9 kΩ.
