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).

•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.
Figure 2-1 - The Buttons
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.

Operation
20221263A 9
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.
3. To select or increase a westerly variation value, apply short
presses on the button. The reading will be negative.
4. Press the button and hold for 2 seconds to save the
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.

Operation
20221263A 11
Press and hold the button for 2 seconds to enter the new
setting.
The display will stop flashing and the arrow points in the
direction to steer, while the digits on the LCD show how much
the boat is off the new set course.
2.5 Alarm Sounding
If the IS15 Rudder is integrated in an IS15 Instrument system it
will sound and flash a warning message in the event there is an
alarm situation.
To cancel a sounding alarm press any button on any of the
instrument displays.
Note ! The flashing warning will remain as long as the alarm condition
exists and disappears automatically when there is no longer an
alarm condition. The sounding alarm will always have to be
cancelled.
Alarm messages
The symbols that are shown when an alarm is triggered are as
below:
‘SHAL’ = The Shallow Water Alarm
‘dEEP’ = The Deep Water Alarm
‘AnCH’ = The Anchor Alarm
‘HIGH’ = The High Wind Speed Alarm
‘Er.XX’ = System failure (Contact your Simrad dealer)

1. Do not remove the protection film on the display before the
installation and set-up is completed.
2. Carefully position the self-adhesive template provided on the
surface where the display head is to be mounted. Allow
sufficient space for the protection cover as shown on the
template when instruments are installed adjacent to each
other.
3. Drill a small pilot hole first, and then check the location on
the other side of the panel or bulkhead to confirm suitability.
Open out the pilot hole to 85 mm (3.4”) using a cutter, or an
electric drill saw (86 mm or 3 3/8”).
4. Drill the four screw holes using a 2.5 mm (0.1”) drill.
5. Ensure that the sealing gasket is correctly located and secure
the instrument using the four self-tapping screws provided.
Apply the front panel corners.
Note ! Ensure that all sockets without cable connections have the
supplied bungs inserted. It is also recommended, to secure the
connectors to the instrument, using the enclosed self-tapping
screws.
Caution Do not over-tighten fixing screws.
Do not use sealing compound on the instrument back.
Do not use WD40 or any solvent on any part of the instrument.
4.2 Installing RF300 Rudder Feedback
The RF300 Rudder feedback unit mounts close to the rudder,
and is mechanically linked to the rudder tiller arm or rudder
quadrant.
Refer to Figure 4-2 for the recommended mounting arrangement.
Note that the RF300 transmitter arm has two slots for the

IS15 Rudder Manual
16 20221263A
transmission link. The slots enable maximum flexibility to
provide the 1:1 mechanical linkage relationship.
Note ! Do not try to remove the transmitter arm from the feedback unit.
The unit is factory adjusted and need no further adjustment at
installation than described below.
As a starting point, it is desirable to set the transmitter rod to the
inner limit of the outer slot if possible. (Refer to Figure 4-2).
Drill and tap the rudder tiller arm so that the Y1 dimension is
equal to the Y2 dimension (Use 4.2 mm drill and 5 mm tap).
Attach the ball joint to the tiller arm, and connect the transmitter
rod to the ball joint at the rudder tiller arm.
Rotate the RF300 transmitter lever until it is set to centre
position. (Use the alignment mark to line up the transmitter lever
to be opposite the cable entry into the feedback.).
Note ! Carefully observe the alignment marks. A rudder feedback alarm
may be the result if the alignment instructions as per Figure 4-2
are neglected.
Attach the transmitter rod to the RF300. Set the RF300 mounting
location to be in accordance with Figure 4-2. The centre of the
RF300 should be in line with the centre of the rudder post.
Mount the RF300 to a suitable platform using the screws
provided. If necessary, add blocking material under the RF300 to
adjust the height of the transmission arm to be level with the
rudder tiller arm.

Installation
20221263A 17
Figure 4-2 RF300 mounting
Note ! Due to space limitations, it may be necessary to cut the length of
the transmitter rod to move the RF300 closer to the rudder post.
Tighten the mounting screws for both the RF300 feedback unit
and the transmitter rod ball joint.
Observe the RF300 while someone turns the helm wheel through
the complete travel from full port to full stbd. rudder to verify
that the mechanical linkage to the RF300 is not obstructed.
