1.1 Stand alone IS15 Rudder
The IS15 Rudder instrument may be used as a stand-alone rudder
indicator shown in Figure 1-1. More instruments (max 3 units
with Roblink Power cable) may be added to the system by using
single cables in a “daisy chain”. Instructions for installing the
rudder feedback unit are found in chapter 4.2.
IS15 Rudder may also be integrated in an IS15 instrument
system and Simrad X-series autopilot systems (AP11, AP20,
AP35).
Please study the different system configurations in section 4.3.

2.1 General Description
The display is divided into two sections, the scale with pointer,
and the LCD. Both are controlled by the two buttons.
The Scale
The pointer indicates the rudder angle and the scale has markings
of “0” (midship), “1/2” and “1” (full deflection).
Full deflection (1/1) is scaled for 45° of rudder travel from
factory. However, the instrument/pointer may be calibrated to
show full deflection (1/1) for smaller rudder angles (see
specifications).
The LCD Display
In normal operation the LCD has two modes:

•Locked Course/Direction to steer
There are two arrows at the top of the LCD indicating what data
is being displayed at any one time. The arrow legend is printed
on the scale. The right arrow points to LOCK for ‘Locked
Course’ mode, the left arrow points to HDG for ‘Heading’ mode.
The Buttons
A given press on any of the two buttons will change the mode
from ‘Heading’ to ‘Locked Course’ mode and vice versa.
The left button is used to enter set-up and installation screens.
The right button sets the lighting level. When in a set-up or
installation screen, both buttons are used to change settings.

2.2 Powering Up
At first time turn on please refer to section 5.1. At normal power
up, the pointer will sweep the scale, and the LCD will show the
software version for approximately one second.
The pointer will then show the rudder angle and the LCD will
show the heading provided this is available as an input.
Note ! It may take 10-15 seconds before the heading is displayed.

2.3 Display backlighting
Press the button and hold for 2 seconds. The display then
presents the backlighting level. Repeat pressing until desired
backlighting level. Selectable values are 1-7 and off (0).
2.4 The Heading Display
The Heading Display is the first display that is shown after
power up. It shows the present heading with the left arrow lit.
•The heading may be referenced to either Magnetic or True
North. If only one type of data is available, and the other
data is required then the local magnetic variation may be
entered, or it may be read in from a GPS if one is fitted. This
may enable the display of True heading when only a
magnetic referenced heading sensor is available.
•If no heading data is available the LCD will show four
dotted lines.
Magnetic variation [Var]
This is a sub-screen to the Heading display.
The IS15 instruments automatically read the Magnetic Variation
compensation from a connected GPS. The compensation is
presented on the screen. You can not adjust the compensation
from the GPS. If you press the button and hold for 2 seconds
the screen just flashes AUtO and returns to show VAr.
If a GPS is not connected you will be able to enter the magnetic
variation manually.
1. Press the button and hold for 2 seconds. The MagVar
reading flashes. It indicates ‘000’ when there is no
compensation for the variation.

2. To select or increase an easterly variation value, apply short
presses on the button. The reading will be positive.

setting.
5. Press the button and hold for 2 seconds to return to the
main screen.
The Locked Course Display
From the Heading Mode a quick single press on the or
push-button will enter Locked Course Mode and the right arrow
will lit on the LCD. If the boat stays steady on course, the LCD
will display the locked course. Whenever the boat is off course
the LCD shows >XX or XX<. ‘XX’ is the magnitude of the
course error and the arrow (<>) points in the direction to steer to
get back on course.
Changing the Set Course in ‘Locked Mode’
This is a sub-screen to the ‘Locked Course’ display and allows
you to view the set course or to manually set to a new course to
steer.
With the LCD arrow pointing right press the button for 2
seconds and the LCD starts flashing.
The LCD will flash the current set course. If you want to
maintain the set course, press and hold the button for 2
seconds.
If you want to change the set course apply short presses on the
or button to set the next course to steer to port or
starboard respectively.
