This manual is an addendum to the IS15 General Manual and
refers to that manual when applicable.
The manual is intended as a reference guide for correctly
installing a Simrad IS15 Expander with speed and depth
transducers and how to interface to peripheral equipment with
NMEA 0183 interface.
Please take time to read the manuals to get a thorough
understanding of the operation and system components and their
relationship to a complete IS15 instrument system.
Other documentation material that is provided with your system
includes a ‘bridge card’, and a warranty card. The warranty card
must be filled out by the authorized dealer that performed the
installation and mailed in to activate the warranty. You will find
the warranty card in this manual.

1.1 Introduction
IS15 Expander is an upgraded version of the IS15 Transceiver.
In addition to electronics for depth sounding and speed/
temperature transducers it offers two NMEA I/O ports and the
capability of driving 8 instrument heads. The instruments are
connected in two “daisy chains”. Further instructions on how to
connect the instruments and peripheral equipment are found in
the manual.
In addition to this manual please also refer to IS15 General

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 Expander can drive a total of 8 instrument heads. They
can be connected to J1 and J2 of the Expander in two “daisy
chains” with maximum 7 instrument heads in one chain. The
total length of the interconnecting Roblink cables should not
exceed 30 m on each chain as shown in Figure 4-3.
Note ! The length of the masthead cables shall not be included in the
above.

Power connection
There is no power cable supplied for the Expander. 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 Expander PCB and
the other end to a circuit breaker. Use a 5 Amp fuse in the line.
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 4-4).
4.4 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 ! Always use twisted pair cables for NMEA data.
Figure 4-7 NMEA out
The NMEA “listeners” must be
connected to either TB6 or TB7.
Figure 4-8 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).

Installation
20220943A 13
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 50 in the IS15 General Manual 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.
−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 a minimum of two NMEA “listeners”.
Interfacing to a Simrad AP11 or AP 20
series autopilot
Use a single cable with two twisted pairs of wire for this
connection.
NMEA Out
The connection will provide speed, depth, temperature and wind
data input to the autopilot.
With a J3000X Junction Unit in the system the autopilot will
also receive GPS data via this connection provided a
GPS/chartplotter is connected to the Expander.
The connection is made to the J3xx Junction Unit Main Board,
Terminals RX1+ and RX1-.
NMEA In
This connection provides heading data input to the instruments.
The connection is made to the J3xx Junction Unit Main Board
terminals TX1+ and TX1–.

Figure 4-9 Simrad Robertson “X” series autopilot connection
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 4-10. In addition connect the chartplotter (port 2) to
J300X, RX1/TX1. On the autopilot and the chartplotter the
interfacing must be set up accordingly.

Connecting a Simrad XX32/XX40/XX50
series GPS Plotter
Use a single cable containing two twisted pairs of wires if you
need to extend the cable(s) that comes with the equipment.
NMEA out
This will provide the chart plotter with speed, depth, temperature
and wind information.
NMEA in
This will provide navigational data to the instrument system.

RFC35N (NMEA) and RFC35R (Rate)
Compass connection
The heading input is normally from the autopilot. In the event
there is no autopilot connected to IS15, a separate compass with
NMEA interface can be connected as per figure 6-15 in the IS15
General manual (recommended) or as per below.
Figure 4-13 Connection to RFC35N or RFC35R Compasses
Note ! Read the wiring instructions that comes with the RFC35R Rate
Compass.
NMEA in: ‘Heading’ and ‘Calibration Completed’ from
compass
NMEA out: ‘Start Calibration’ to compass.
5SETTING-UP
Follow the instructions in the IS15 General Manual, Section 7
and IS15 Wind Manual, section 6. Groups 8 and 9 in the table in
section 7.2 of the General Manual should be disregarded when
setting up.

6EXPANDING THE SYSTEM
You may add another 7 instruments to an IS15 system that
contains an IS15 Expander. Please refer to Figure 6-1 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 4-3. 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.
