2.5 Screen Group 1: Depth, Speed, Trip Log
There are five screens in this group (all have one or more sub
screens).
Screen 1
DEPTH
BOAT SPEED
TRIP LOG
• The upper screen section displays ‘DEPTH’, unit (e.g. ‘mtrs’)
and the depth value. An arrow indicates a rising (↑) or falling
(↓) bottom. A bargraph indicates the strength of the signal.
‘EXT’ replaces the bargraph if the depth signal is from an
external source on NMEA format.
• The middle screen section displays ‘BOAT’, unit (e.g. ‘kts’)
and boat speed value.
• The lower screen section displays ‘TRIP’ and the trip log
value in nautical miles.
Note !
If the system depth transducer signal is lost, the Depth display
will flash the last good echo value for one minute, then it will
show ---. If there is an alternative depth input to the system on
NMEA format and the sounder is set to Off, this depth will be
displayed instead.
Screen 1 has three sub screens. Setting of the boat (water) speed
damping, switching the depth sounder on and off, and setting the
level of depth damping.
Speed damping
The displayed speed has four damping levels (0-3), 0=Off.
On power up the last set damping level is selected.
To change the speed damping level follow the procedure in
Figure 2-2, page 12 and select the wanted damping level. The
higher the figure the more damping.
To Set the Depth Sounder On or Off
In certain circumstances, e.g., to save power in known waters or
when out of depth range, you may want to turn the depth sounder
off. It is also recommended to turn it off if there is another
sounder on board operating on the same (200 kHz) frequency.
Interference between the two can thus be avoided.
20220760L
13
IS15 General Manual
Note !
When the sounder is turned off, the display will show OFF
instead of the depth reading.
Follow the instructions in Figure 2-2 to access the depth sounder
ON/OFF screen. With the ON-screen flashing select OFF and
return to Screen 1 as per instructions.
This setting is not affected by power off/on or a Communication
Reset, but defaults to ON after a Master Reset.

IS15 General Manual
True Wind Speed Alarm limit
Refer to Figure 2-2, page 12 to set the wind speed alarm limit (099 knots).
Screen 3
WIND DIRECTION
The screen displays the Wind Direction in degrees and the unit
(‘T’rue or ‘M’agnetic). Refer to page 20.
Screen 3 has a sub screen for setting the magnetic variation.
Refer to page 21.
Notes !
1. The Wind Direction is calculated from available heading
data. The wind direction given is the effective wind direction
over the water. The display will be most accurate after a
period on one heading, however, it will respond rapidly to
course changes.
2. If there is no heading data, but Course Over Ground (COG)
data is available then the Wind Direction is calculated from
the Course Over Ground. In this case there is compensation
for the tide, and the wind direction given is the effective wind
direction over the ground. However the display will not be
accurate after a course change, and will require a period on
one heading before it is correct. (Any errors in the
Navigation Receiver’s fix will degrade the accuracy of the
wind direction.)
3. The Wind Direction is referenced to either Magnetic or True
North as selected for the heading. The data can be converted
from one to the other if the local magnetic variation is
available (page 20).
4. Note that the ‘TRUE’ and ‘APPARENT’ readings that are
shown in this group of screens relate to the Wind Speed and
Angle, and not the Wind Direction.

There are five screens in this group:
Screen 1
DEPTH
• The upper screen section displays ‘DEPTH’ and the data unit,
e.g. ‘MTRS’. An arrow indicates a rising (↑) or falling (↓)
bottom. A bargraph indicates the strength of the signal. If the
depth signal is from an external source on NMEA format, an
“E” will replace the bargraph.
• The lower screen section displays the water depth reading.
Note !
If the system depth transducer signal is lost, the Depth display
will flash the last good echo value for one minute, then it will
show ---. If there is an alternative depth input to the system on
NMEA format and the sounder is set to Off, this depth will be
displayed instead.
Screen 1 has two sub screens. One for switching the depth
sounder on and off and one for setting the depth damping.
Depth Sounder On / Off
In certain circumstances, e.g., to save power in known waters or
when out of depth range, you may want to turn the depth sounder
off. It is also recommended to turn it off if there is another
sounder on board operating on the same (200 kHz) frequency.
Interference between the two can thus be avoided.
Note !
When the sounder is turned off, the display will show OFF
instead of the depth reading.
Follow the instructions in Figure 3-2, page 32 to access the depth
sounder ON/OFF screen. With the ON-screen flashing select
OFF and return to Screen 1 as per instructions.
This setting is not affected by power off/on or a Communication
Reset but will default to ON after a Master Reset.
Depth damping
The displayed depth has four levels (0-3), 0 = Off. On power up
the last set damping is selected. To change the depth damping
level follow the procedure in Figure 3-2, page 32 and select the
wanted damping level.
The higher the figure the more damping.

4.1 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 scale indicates heading in degrees and the four main
bearings N, S, E, W. The pointer always indicates True or
Magnetic Heading.
The LCD Display
In normal operation the LCD has two modes:
• Heading
• 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.
20220760L

IS15 General Manual
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 4-1 - The Buttons
4.2 Powering Up
At first time turn on please refer to section 7.13. At normal
power up, the pointer will TURN to the top, and the LCD will
show the software version for approximately one second.
The display and the pointer will then show the current heading.
Note !
It may take up to 20 seconds before the heading is displayed.
4.3 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).
4.4 The Heading Display
The Heading Display is the first display that is shown after
power up. The pointer shows the present heading, and so does
the LCD 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 data is available the LCD will show four dashes, ‘----‘
and the pointer will point upwards.

5.5 Instrument Software Information
V1R1: Beta version, not used in ordinary production.
V1R2: First production version
V1R3: Upgraded version with added features.
• Trip log replaces sea temperature on first screen of IS15
Combi.
• In Locked Course mode the LCD on IS15 Compass has been
changed to show deviation in degrees from locked course.
• Improved log calibration procedure. Possible to set Log
reading as percent (%) of default value. Log calibration can be
set to same value on identical boats.
• Boat speed always reads 0.0 at zero speed. (V1R2 may show
- - - at turn on and a ‘residual’ speed value when slowing
down to zero speed).
• Improved boat speed and wind speed damping.
• Improved damping of heading displays.
• Depth transducer remains OFF at turn on if it was set to OFF
while the system was running.
• Test screens added to Installation Menu to simplify trouble
shooting.
• Roblink can be turned off and thus eliminate a possible
interference when a single instrument is connected as NMEA
repeater.
• ‘Communication reset’ added. Saves all settings in the event
an anomaly in the system functions calls for a reset.
V1R4: Substitutes V1R3 that contains a bug. V1R3 should not
be used.
V1R5: Upgraded version with added features.
• Two new display screens in Display group 4, Nav. Screen 1
shows heading, boat speed and rudder angle. Screen 5 shows
waypoint bearing and COG. Screen order has been altered.
• Two new screens in the Installation Menu Group 8, Rudder.
Screen 1 shows rudder angle offset and screen 2 shows
rudder angle source.
• New Setup screen for Depth damping in Screen group 1.
• Default depth offset change from –0.3 m to 0.0 m.
54
20220760L
Technical Specifications
• Increased damping of wind display at level 2, 3 and 4.
• Increased damping of boat speed at level 2 and 3.
• Instruments output True Wind Angle and Speed in addition
to Relative Wind Angle and Speed.
• NMEA depth sentence ‘DBT’ added.
• Access to all offset adjustments when the instrument is used
as NMEA repeater.
• Corrected a bug in the UTC offset.
• New NMEA In/Out screen in the Installation Menu Group 1
General. Allows you to manually change the NMEA ‘talker’
port to a ‘listener’ port.
V1R6: New software to comply with PCB Ass’y Revision H (B
on round heads) onwards. V1R6 is backwards compatible with
previous software and hardware versions.
Notes!
1. PCB Ass’y with this revision does not accept V1R2 or V1R4
software.
2. On IS15 Combi, V1R6 should replace V1R5 if the display
turns pale in bright sunshine.
3. V1R6 is backward compatible with V1R2 and V1R4.
However, anomalies may be observed if attention is not
being paid to the NMEA interface. In systems with mixed
software, do not interface NMEA ‘talkers’ to heads with
V1R2 software.

6.4 IS15 Transceiver Mounting
The IS15 Transceiver is not weather proof and should be
mounted vertically in a dry place with the cable outlets pointing
downwards.
The unit is mounted to bulkhead or panel by four screws through
the mounting lugs.
64
20220760L
Installation
6.5 Transducers
Follow carefully the instructions that come with the speed/temp.
and depth transducers.
Mounting Guidelines
Depth Transducers
• The main source of the vessel generated noise is the propeller.
• The deeper the transducer projects the lower the risk of
aerated water.
• On displacement hulls place the transducer 1/3 aft along
waterline.
• Avoid locations near the keel or bow due to aeration.
• Mount the transducer on the side of the hull where the
propeller is moving downward.
• On sailboats mount forward of the fin keel, with minimum
dead rise.
• On planing vessels mount aft near the keel to insure water
contact at high speed.
• On I/O’s mount close to the engine.
• On inboards mount well ahead of the propeller.
• On higher speed vessels (+27 knots) mount in known good
locations.
• Do not mount near water discharge or behind struts or fittings,
which will create turbulence.
• For dead rise greater than 10 degrees a fairing is
recommended.
Speed Transducer
• On sailboats the sensor should be mounted close to the
centerline and 12 to 24” ahead of the keel.
• On displacement vessels the paddlewheel should be mounted
well aft so the sensor is always in contact with the water.
• Do not position the paddlewheel directly ahead of a depth
transducer.
• Do not locate the speed sensor behind struts or thru-hull
fittings.

6.6 Cabling
Figure 6-5 Interconnection – Principle diagram
Choosing the Cable Routes
After you have decided on the system and mounted the
components of the IS15 System, the next step is to route the
cables between the various parts of the system and to the power
supply. Choose the most direct paths while avoiding the
following hazards:
• Sharp bends or kinks in the cable
• Hot surfaces (exhaust manifolds or cooking equipment)
• Rotating or reciprocating equipment
• Sharp or abrasive surfaces
• Door and window jambs
• Corrosive fluids or gases
Total length of Roblink cables
The IS15 Transceiver can drive a total of 7 instrument heads.
They can be connected in one single “daisy chain” with the
Transceiver in one end, or in two chains with the Transceiver as
a link. The total length of all interconnecting Roblink cables
should not exceed 30 m as shown on Figure 6-6.

Securing the Cables
After the ideal cable routing has been established, use tie-wraps,
‘P’ - clips or other fixings to secure the cables along the routings.
Note !
To prevent chafing add protection for the cable jackets where the
cables pass through bulkheads, or past sharp edges.
Secure the cable near the terminals for strain relief. See also
Figure 6-7 below.
Secure the cable ends with enough slack to allow for easy
connection / disconnection with the instrument removed from its
location.
Cut any spare wire ends to an appropriate length.
20220760L

IS15 General Manual
Securing the connectors
It is recommended that for extra security you secure the
connectors with the enclosed self-tapping screws.
Figure 6-7 Securing connectors to the instrument
Make sure that all empty sockets have the protection plugs
inserted. Coat the connectors with silicone grease or petroleum
jelly. These products will not harm the instrument.
6.7 Instrument head connections
Figure 6-8 - Instrument Connections
The instrument head has four identical two-pin connector sockets
protected by rubber plugs. Each socket is identified by number
and signal markings.
Caution !
68
NMEA cable must be plugged into connector no. 4. Wrong
connection may damage the connected equipment.
20220760L
Installation
Interconnections
Connection between the instrument head and the IS15
Transceiver is made by the 10 m (33’) Roblink cable supplied
with the Transceiver.
Connect the Roblink cable between one of the three Roblink
sockets on the IS15 Transceiver and the PWR-ROBLINK socket
(1) on the display head.
Interconnection between instrument heads is made by the
supplied 0.3 m Roblink cable. Refer to Figure 6-5
Interconnection diagram on page 66.
6.8 NMEA connections
General
The NMEA port on the IS15 instruments is unidirectional, i.e. it
is automatically configured for input (listening) or output
(talking). Thus you will need a minimum of any two instrument
heads to make the system both ‘listen’ and ‘talk’ (I/O).
Note !
Roblink cables have to be ordered separately for NMEA
connections (see page 67).

6.9 IS15 Transceiver
This unit contains the depth and the speed/temperature
electronics. The power supply (battery) and the transducers are
connected to the unit.
The unit has three Roblink connectors for instrument heads and
wind transducer.
Speed/temp transducer and depth transducer are hard-wired to
plug-in screw terminals on the PCB (pwr terminal is fixed).
• Remove the top cover to get access to the plug-in terminals.
• Press the cable end through an appropriate recess in the
gasket (ref. to Figure 6-5). Remove about 2 cm (0.8”) of the
cable insulation.
• Pull out the plug-in terminal before connecting the wires.
• Be careful to prepare all wires on each cable before putting it
through the gasket to avoid strands getting onto the PCB.
• Insulate the shields by electrical tape or similar.
• Make the connections according to the following connection
diagrams.
• Leave sufficient free wires so that the plug-in terminals can
be easily connected/disconnected.
• Ensure that no strands are left inside the unit before
putting on the cover.

IS15 General Manual
Figure 6-17 Depth Transducer connections
When installing Airmar depth transducers with a 200KHz-G
designator, a 2 Kohm resistor should be connected across the
terminals as shown. The resistor provides a better impedance match to
the particular element used in these transducers, hence erratic readings
are avoided in very shallow waters.
The P52 and the SS505 listed by Simrad have a 200KHz-G designator
and will need the 2 Kohm resistor. Other Airmar depth transducers
listed by Simrad have a 200KHz-U or 200KHz-B designator.
Figure 6-18 Speed/Temp Transducer connections
74
20220760L
Installation
Power connection
There is no power cable supplied for the Transceiver. Use a
cable with minimum wire gauge of 1.5mm2 (AWG14). The outer
diameter should be 10 mm (0,4”) to ensure a tight fit through the
gasket.
Connect the Power cable to TB1 on the IS15 Transceiver PCB
and the other end to a circuit breaker.
The connection is polarity protected and monitored by a green
LED. If a red LED is lit on the PCB, swap the supply wires (see
Figure 6-16).
6.10 IS15 Instruments as NMEA repeaters
Figure 6-20, Figure 6-21 and Figure 6-22 are examples of how
IS15 instruments can be used as NMEA repeaters. Depth, speed
and temperature can be displayed when connected to a Simrad
CEXX Chart plotter/Echo sounder or CAXX Multifunction
radar. Any preferred combination of instruments can be used, the
IS15 Combi for example is an excellent display also for wind
data presentation.
Installing the Roblink Power Cable
The configuration in Figure 6-20 is limited to a total of 3
instruments and a Roblink Power Cable (P/N 22093587) is
required to enhance the Roblink signals. Connect the cable to a
circuit breaker. Extend the cable if necessary using a wire gauge
of 0,75 mm2 (AWG18).
Notes !
1. If an IS15 Wind Transducer is connected to the IS15
instruments when using this configuration, it must be
plugged into connector no. 2 (Roblink) on instrument head
no. 3. Refer to note 2 for NMEA connection.
2. If only a single instrument is installed (Figure 6-22) there is
no need for the Roblink Power Cable. Simply cut the 0,3 m
(1’) cable that comes with the instrument in two and extend
the halves to the 12V supply and the NMEA source
respectively using twisted pair cable. – Also refer to
instructions for Roblink turn-off (paragraphs 7.3 or 7.13.)

NMEA connections
General
The IS15 Expander has two sets of NMEA I/O ports. TB5 and
TB6 are input and output ports no. 1 respectively and TB11 and
TB7 input and output ports no. 2 respectively.
Note !
82
Always use twisted pair cables for NMEA data.
20220760L
Installation
Figure 6-27 NMEA out
The NMEA “listeners” must be
connected to either TB6 or TB7.
Figure 6-28 NMEA in
The NMEA “talkers” must be
connected to either TB5 (GPS) or
TB11 (Autopilot and other). The IN
ports are non polarized (colour
independent).
Notes !
1. The NMEA input ports are dedicated, i.e. port no. 1 is for
GPS/Plotter data and port no. 2 for other data. Refer to the
NMEA table on page 56 to identify which signals (GPS_Data
and Nav_Data) and corresponding NMEA sentences that
should be connected to TB5 (port 1).
2. As a rule of thumb, the GPS/Chartplotter should be connected
to TB5 (input) and TB6 (output), whilst the autopilot should
be connected to TB11 (input) and TB7 (output).
3. Please observe the following:
− IS15 will read depth on NMEA provided the IS15 depth
sounder is turned off.
− IS15 will read wind speed and angle on NMEA when
there is no wind transducer connected.
− IS15 will not read water speed and temperature on NMEA
when there is an IS15 Expander (or IS15 Transceiver) in
the system.
4. The output ports (TB6, TB7) are outputting parallel data and
each port can drive two NMEA “listeners”.

Note !
With a J300X Junction Unit in the autopilot system you may
have redundancy and a higher heading output rate if you run a
separate and direct NMEA interface between the chartplotter
and the autopilot.
In that case connect the IS15 Expander to J300X, RX2/TX2
instead. Connect the chartplotter (port 1) to IS15 as shown in
Figure 6-12. In addition connect the chartplotter (port 2) to

Setting-Up
Follow the instructions in Section 7 and in the IS15 Wind
Manual, section 6.
Expanding the system
You may add another 7 instruments to an IS15 system that
contains an IS15 Expander. Please refer to Figure 6-34 and
observe the following:
• The Main system is powered by the Expander
• The Secondary system is powered by an IS15 Power Supply
• The two systems are interfaced on NMEA using a single
Roblink cable between the two
• The Secondary system is a repeater system to the Main system
• All sensors are connected to the Expander
• All NMEA interface to peripheral equipment is to the
Expander
Please observe:
1. All system units should be the latest version.
2. The Power Supply has a 5m (16’) Roblink cable as standard.
3. If you need to extend the cables, please order standard IS15
cables and the cable adapter (joiner) as per our price list and
observe the max. cable lengths as per Figure 6-6. Maximum
recommended (NMEA) cable length between Main and
Secondary system is 70 m (230’).
4. Plan your installation so that heads from the two systems are
not placed adjacent to each other. You may notice a minor
delay in response between the Main and the Secondary
system depending on the type of information you are
reading. This is caused by the transfer time on NMEA
format.
5. When commissioning, start with the Main system, then
duplicate on the Secondary system, i.e. first time turn-on,
units, off-sets, illumination bank, etc. Perform the
calibrations using the Main system and then enter the
calibration values into the Secondary system.
6. Normal operational settings, e.g. depth alarms, damping and
illumination must also be set on both systems.
7. You can only turn off the IS15 depth sounder from the Main
system.

Note !
Always turn on all NMEA “listeners” and “talkers” connected
to the system before the first time you turn on the IS15 system.
This includes turn on after a COMMUNICATION RESET or a
MASTER RESET. The system will then automatically configure
the IS15 NMEA ports as talkers (NMEA out) or listeners (NMEA
in).
Before leaving the factory a Master Reset has been performed on
all instruments. The first time power is applied to an instrument,
the display will prompt you to press the illumination key.

Screen 1
ILLUMINATION BANK
The IS15 instrument system can have two separate illumination
banks of instruments. Setting the lighting level on one display
will set all the other displays in that bank to the same level, but
will not effect any displays in the other bank. For instance, the
lighting level can be independently controlled for:
• The cockpit and chart table instruments of a yacht.
• The cockpit and mast instruments on a yacht.
• The cabin and flybridge instruments of a motor yacht.
Note !
You can also have individual lighting on all instruments. Then
the illumination bank setting must be 0.
Screen 2
CONTRAST
The LCD on IS15 Series instruments can be set to one of eight
contrast levels to best suit the viewing angle of the particular
installation.
The default level (level 4) is suitable for a wide range of viewing
angles and will probably not require alteration. However, view
the display from different angles and adjust if required. In
twilight or in the dark use appropriate illumination when
adjusting the contrast.

SHOP MODE
The instrument has a demonstration mode that can be activated
by selecting ‘Shop Mode’ On. This function is very useful for
dealers when they want to demonstrate the IS15 system or when
it is put on display on a show. The Shop Mode is turned off
when power is turned off.
Note !
When in Shop Mode the instruments will display external data if
data is available as input from sensors.
Screen 4
NMEA IN/OUT
This screen allows you to manually change the NMEA ‘listener’
port = NMEA IN to a ‘talker’ port = NMEA OUT, or vice versa.
Hence you need not make a Master reset or a Communication
reset. Refer to chapter 7.1 First time turn on. See also note
below.
The setting is local to each instrument.
Note !
If there is an active ‘talker’ connected to the NMEA port, you
will not be able to change this port from ‘IN’ to an ‘OUT’ port
unless the ‘talker’ is disconnected.
Screen 5
ROBLINK ON/OFF
This screen allows you to turn the Roblink Off (or On). The
setting is local on each instrument.
Notes !
1. The Roblink must be turned Off when the instrument is used
as a single NMEA repeater. However, if more heads are
connected as NMEA repeaters in a daisy chain the Roblink
must be On.
2. When the Roblink has been turned Off it will not default to
ON even after a Master Reset. If required it must therefore be
turned On again using the procedure above.

on the Combi, the display will start counting from 136.
There are three more displays available for roblink testing:
Message rate
Messages are sent with a fixed rate from 1 to 5/second. Example:
Heading (HDG) is sent with a rate of 5 and depth (DPT) with a
rate of 2.
Under normal operation the numbers are steady. If the reading
becomes erratic it indicates a problem on the Roblink.
Checksum Err(or)
Counts up detected check sum errors. A check sum error up to
5% of sent message is acceptable.
Verify how much each message is counting up in a periode of
one minute.
Examles:
If a message with a rate of 1 has more than 3 errors in a period of
60 seconds, it indicates a problem on the Roblink.
If a message with a rate of 5 has more than 15 errors in a period
of 60 seconds, the same problem exists.
The fourth display tells you if an instrument is sending NMEA
data to the Roblink.
20220760L
115
IS15 General Manual
Send
Displays ‘-Tx’ if the particular instrument is sending the
particular message on Roblink. Only the instrument receiving
data from NMEA and sending it to the Roblink displays ‘-Tx’.
Actions to Roblink test results:
1. Zero (0) reading means ‘no message available’.
2. If the numbers are continuously flickering or counting down,
perform a Communication Reset on the system.
3. Make sure the recommended cable length or number of
instruments in the system are not exceeded. See Figure 6-6.
4. Check all NMEA connections.
5. Check the output rate of the NMEA ‘talkers’ connected to
IS15. The rate should not be slower than 0.7 Hz.
Note !

A Personal Computer (PC) does not comply with the NMEA
hardware specifications. Always use a proper interface between
the PC and the IS15 NMEA ports to avoid possible anomalies in
the IS15 performance.

Maintenance
9 MAINTENANCE
9.1 General Maintenance
Caution !
Do not use any abrasives, chemical cleaners, petrol or diesel to clean
the units.
The instrument heads will require no maintenance apart from
occasional cleaning. Use fresh water and a mild soap solution
(not a detergent).
9.2 Annual Maintenance
Check all connections to the instruments and, if necessary, cover
with silicone grease or petroleum jelly.
The wind transducer is a robust unit that should give you years
of reliable service. However, it will benefit from an application
of silicone grease to the connector at the beginning of each
season. It is also recommended that the wand is removed over
Winter if the boat is not in use. To prevent corrosion of the
connector, always fit the protective cap to the socket when the
wand has been removed.
Note !
A broken or lost wind vane can only be replaced by a recalibrated unit from the factory.
A broken anemometer cup may be replaced by the dealer/owner.
9.3 Removal of Instruments
1. If rear access is possible unplug the Roblink connectors from
the back of the instrument.
2. Remove the four front panel corners and the fixing screws.
3. Pull the instrument free from the panel, being careful not to
strain the cables if they have not yet been disconnected.
Unplug the Roblink connectors from the back, and make up
the cables if necessary.

IS15 General Manual
9.4 Return for Service
Please ensure that an instrument that is believed to be faulty is
correctly installed, the cabling is in good condition and correct,
that all connections are secure, and that a correct supply is
present at the Roblink/power connector.
Should the unit have to be returned to your dealer, adequate
packing must be used. Please ensure that your name, telephone
number, return address, a clear fault description, and if possible a
copy of the proof of purchase are included with any returned
equipment. Simrad and their representatives are not responsible
for any equipment lost in transit.
Please quote the instrument’s serial number in all
correspondence. This is found on the back of the instrument.
9.5 Local Master Reset
When an instrument is leaving the factory a Master Reset has
been made. However, if an instrument is being used in a
different system or setup, you can perform a local Master Reset
on the instrument in that system before you disconnect it and
move it to a system where you want to put it.
Refer to screen 4 on page 93 or screen 6 on page 104.
1. Turn off the Roblink as per instructions
2. Perform a Master Reset as per instructions
3. Turn on the Roblink as per instructions
You can now install the instrument in another system without
having to make a system wide Master Reset and loose the
existing calibration and settings in that system.
