Introduction
System introduction
Sailmon system provides a whole new look to yachting electronics for a wide range of
vessels, from top end racing yachts to weekend cruisers. Sailmon products are developed to
bring, combine and view all data on board, anywhere, anytime.
The heart of the Sailmon network is the E4 processor. This small but powerful central
processor unit provides all the navigation information that is needed. With more than six data
compatibilities, it is the smartest and most advanced CPU on the market. Powered with
either 12 or 24VDC it is possible to install the E4 nearly anywhere on board. With the use of
WiFi, data is accessible everywhere.
The sunlight viewable displays enable all data to be selected and displayed at all locations.
Using the standard 100BASE-TX fast Ethernet communication network, all displays can be
connected to one E4 processor. Sailmon displays use our proprietary S-NET cable and
connector system, which contain power and data wiring, made from waterproof components
to survive the harsh conditions found at sea. Power and ethernet is combined in our
dedicated SAILethernet.
To complete your system, sensors from any manufacturer can be added using our
interfacing boxes, including load cell, wind instruments, through hull transducers and linear
inputs. You can also use existing sensors when you upgrade to the E4

1.1 Product overview
The Sailmon model E4 processor will provide your vessel with the possibility to view all your
data everywhere on board. Combining sailing data with advanced racing technology, the
processor enables you to configure, calibrate and view your boat data everywhere. This way,
when installed in either an existing system or working on its own, the processor will connect
to different data protocols and stream all data to our wired display or any smart device using
our USB wifi dongle or on board access point.
Due to its number of data ports, the E4 can be connected to almost any network or can be
set up as a standalone CPU to run your Sailmon equipment.
The Sailmon E4 processor will work as a high end calibration system for different vessels.
The E4 provides the following capabilities:
1.1.1 Functionality
● To receive raw data from a wide range of sensors such as wind, boat speed,
compass and mast rotation,
● Provide very sophisticated multidimensional calibration of data.
● Produce calibrated and derived data such as: True Wind Speed & Angle, calibrated
Apparent Wind Speed & Angle, calibrated Boat Speed, derived tidal information and
drift.
● To (re)publish sensor-calibrated and derived data on the various networks
● To calculate values based on the data and your polars such as Target Speed or
performance ratio.
● To receive and re publish data from other applications. For example, to publish
Bearing & Distance To Waypoint (BTP & DTP) from tactical racing software on NMEA
interfaces.
SAILMON
Page 11
1.1.2 Instrument Integration
The E4 system can use a wide range of sensors based on NMEA, B&G, Nexus or
Raymarine protocols. Sailmon can provide support for various other sensors via optional
Sailmon boxes such as WindBox, LoadcellBox and LinearBox. The Sailmon E4 system is
very flexible:
● It supports various interfaces for existing hardware on board such as B&G,
Raymarine and other sensors or hardware
● It can even support and bridge different legacy networks simultaneously and upgrade
their capabilities.
● It allows the re use of old system displays from many manufactures, so no need to
replace them. For example, Garmin GNX, B&G Fastnet or Sailmon Element X and VII
can be connected to the system.
1.1.3 Software
Many other applications interface with E4 via Ethernet. Expedition, Adrena and Deckmann all
can be combined into the Sailmon system. Besides this, Sailmon offers E4 users the
following software functionality:
• NavDesk on PC (Windows) or Tablet (IOS, Android) for system control
• Screen view to enable a tablet or PC to act as Sailmon Display
• Crew View on mobile / tablet (IOS, Android) to act as a preset display.
1.1.4 Connectivity
Protocols that can be connected:
● NMEA 2000
● NMEA 0183
● Seatalk
● Fastned
● Ethernet
● Nexus FDX
● USB
The Sailmon instruments communicate using standard 100Mbps ethernet allowing for fast
and flexible integration. Each device is a DHCP client which allows our system to be
integrated in the yachts network. All system control is done using our Navdesk application.

1.2.5 LED Status
On top of the E4, several blue LED lights are visible. LED’s indicate sensors connection and
correct operation. When connecting NMEA 2000 it can take slightly longer for the blue LED
to show up due to NMEA 2000 protocol .
1.3.0 Sensor connecting
Port 1 & 2 are set in a default mode when the E4 is delivered to NMEA 0183. Each model E4
port must be set during commissioning using the Sailmon tool. Connect a PC to the E4 for
setting the correct port option before connecting the cable to the port.
Port I/O and II/O
Both ports can be used for connecting several different protocols, only one protocol can
be used at a time per port. You can set up which protocol to use with the Sailmon tool.
NMEA 0183
The NMEA 0183 protocol can be used in both regular (4800bps) and high speed
(38400bps).
If you require more than one NMEA 0183 input you will need a NMEA multiplexer.
Please contact Sailmon support if you need any assistance.

1.4 E4 installation
Warning: Before starting the installation, make sure all electrical power is switched
off, the power supply is suited for the desired installation and the right cabling is
being used.
Make sure the E4 is mounted in a dry and well ventilated area., the E4 is not designed to be
watertight and should therefore not be in contact with water. Securely mount the E4 in the
desired location and mount with four screws.
The E4 has no orientation components so it is possible to mount the processor in any angle.
However, it is recommended to place the E4 with its connection ports downwards.
Connect data connections using image 1.2. Be sure to observe connector keyway alignment.
A bad connection will lead to data loss and the system under performing.
Ensure cables are suitably supported and are located where they will not become damaged
in any way. Consider cable protection in exposed cable runs.

1.4.1 Network installation
It is vital for good communication that all network cables are of good quality and are being
used as designed . Ensure that all non sailmon products are in good condition and are fit for
purpose.
When connecting the E4 to a PC or tablet, several possibilities occur:
Ethernet:
Network cable: Simply connect the network cable into the ethernet port of the E4 and the PC
SAILMON
Page 21
Switch:
Sailmon displays are connected using the ethernet port of the E4. Because of this, there are
no more ports available to connect the PC to. A network switch is used to extend the number
of network ports in your system.
Wireless
TP - link: With the USB port of the E4, there can be a USB / Wifi stick connection. This way,
the E4 will create its own wireless network which can be detected by any wifi device
SAILMON
Page 22
4G Router
One of the benefits of a separate router is the possibility to insert a 4G SIM card so you are
able to connect to internet. Besides this, the wifi network can be used to view data on a
tablet or smartphone.
SAILMON
Page 23
1.4.2 Sailmon Network
Overview
Sailmon devices (the E4 Processor and all Screens) communicate using IPv4 over a
standard 100 MBit/s ethernet network. Using an S-Net box, or a direct ethernet connection to
the E4, it is possible to use standard networking equipment. Sailmon devices are designed to
work in any existing local area network, where they will acquire IP addresses from a DHCP
server and not interfere with other devices or services. Sailmon can be deployed as a
standalone as well, without a DHCP server on the network. In this case Zeroconf addressing
is used. The Model E4 processor can be configured to provide a DHCP server, or act as
simple Wifi access-point for convenience.
Sailmon applications (NavDesk, SailmonTool, Mobile Apps, etc.) are designed to be
connected to the same LAN as the devices and require no additional configuration.
Applications will automatically detect the presence of Sailmon products using two parallel
methods of discovery via UDP heartbeats and requests. The exact TCP and UDP port
numbers used by Sailmon are described in the next sections.
More complex LAN configurations, as well as external Wifi access-points, are possible given
they can fulfill the following requirements:
● At least 10 Mbps unicast bandwidth available between nodes
● At least 1 Mbps bandwidth for multicast or broadcast messages
● All given UDP and TCP ports must be open in both directions
● Additional ports are needed depending on the installation (see below)
● UDP multicast or broadcast packets must be able to reach every participant
Complex network installations
All Sailmon devices are required to share the same network. However, it is possible to run
Sailmon applications from a remote network, given they are connected by layer 2 (switches,
Wifi APs) or layer 3-4 (routers).
Unicast (point-to-point) communications generally work without issues over Wifi, and even
between multiple routed LANs or VLANs, which makes the initial discovery via UDP multicast
the most critical requirement. The network installation must ensure that packets to the
Sailmon multicast group “239.255.83.77” on ports 4019 and 4020 are not filtered and can
traverse to all desired devices. This means that switches may need to use “IGMP snooping”
option if the packets are filtered otherwise. When multiple networks / IP address ranges are
SAILMON
Page 24
present, a router must be configured to forward multicast packets to the neighboring
networks. Additional forwarding of UDP traffic may be required (see optional ports).
UDP Traffic
Ports required for Sailmon Apps
4019 Heartbeat requests
Applications send broadcast requests to this port. Sailmon Instruments will respond by
sending their heartbeat packet back to the source port on the requesting computer. This is a
fallback if clients are not able to join the multicast group, and used as a quick way to discover
devices on the network.
4020 Heartbeats
Source of heartbeat broadcasts sent every 2 seconds by Sailmon devices. Heartbeats are
required by every application to find the IP of the Sailmon server in an unknown network.
Heartbeats are broadcast and sent to the Sailmon multicast group. Join the multicast group
to receive them. They contain the serial number, software versions, etc. for each device.
4021 System configuration
Sailmon tool will send broadcast packets to all Instruments for global settings and server
management.
6130 Instrument commands
Receive port for commands to real or virtual Instruments. Used to trigger reload of
configuration and to show or hide the help screens during initial configuration.
6150 Data requests to Sailmon server
Used to request data values from the Sailmon data server. The client sends unicast UDP
packets containing desired IDs to the server at port 6150. The server responds to the source
host and port with the current values and status flags. When blocked, instruments will show
“no data”.
6152 Raw data output from server
Output port of live raw data values from all sensor
Ports required between Sailmon Devices
6000 Commands / requests for backlight control
Receive port for commands / requests to the backlight controller on each screen.The
backlight controller will respond to source host and port.

3.1 Displays
3.1.1 product overview
Sailmon displays can be purchased in either Portrait or Landscape version. In both cases the
dimensions are the same. The difference is in the high end polarisation filter and software
settings. Casings are different shown by the Sailmon logo position.
When installing a display it will need to be connected to the ethernet port of the E4. The
SAILethernet is needed to combine both the data and power from the power supply and E4
to the display.
The displays can be connected in daisy chain, this means, only one cable is necessary from
your switching panel to the mast. Using Fast-lock waterproof connectors will reduce the
installation effort to a minimum. Sailmon displays includes the most powerful and intelligent
technology available, including automatic backlight control with an ultra-high dimming ratio of
1:3000.
This allows absolutely perfect readability under all conditions for convenient reading during
day and night. Even high contrast and intense colours are maintained during night sailing.
Perfect sunlight readability is achieved with a high-performance anti glare front screen. The
front glass is optically bonded to the TFT display, avoiding an air gap. Therefore, you will
never experience a foggy display. The displays are further optimized for ultimate visibility
with polarized sunglasses. Using polarized sunglasses will even improve the visibility of the
instrument.

4.1 Sailmon components
4.1.1 Snet connector
To connect displays to the Sailmon network or to each other, a Snet connector is used.
These connectors are suitable for use outside the hull due to the IP classification. This
classification is only effective when connectors are attached to each other. Loose connectors
can easily be damaged by moisture.
Snet cables can be purchased in two types:
● Ready - to - go: Customers have to know the exact length of the desired cable since
there will be a connector on both sides. Pulling the cable through the vessel will be
harder due to the large diameter
● Self build: On one side of the Snet cable, a female connector is already attached. The
male connector is provided to be mounted by the customer. Please note that for this,
a special crimp tool is needed, which can be purchased from Sailmon
Connectors should
never be forced together
due to the keyway in the
male connector. Gently
push the connectors into
each other and turn.
When turned correctly, a
small ‘click’ should be
heard. The connectors
are now locked.
Make sure you put the
waterproof dust-cap on
the last instrument to
prevent infiltration

4.1.2 SAILethernet
This box has to be connected to the ethernet port of the E4 and the ship's power supply.
The SAILethernet powers and establishes a connection between your display and model E4
over ethernet.
This connection can be achieved by
adding both devices to an existing
network or connecting them directly
together.
The SAILethernet converts a regular
power cable and a regular cat-5 cable
into our proprietary 6 core S-NET
cable, which runs from the instruments
to the SAILethernet.

Installation
Choose a dry and protected place for the Wind Box. The Wind Box is designed to be
installed inside the hull.
Do not install your Sailmon windbox on the head of the mast. This will make lighting
protection impossible and the NMEA 2000 specifications for the maximum drop cable
length are likely to be exceeded.
Feed the wind sensor cable into the left cable gland of the Wind Box and connect the wires
according to the color scheme printed on the circuit board
Operation
In case of sensor failure or incorrect connection, the blue status LED will blink 5 Times /
second.
If blue LED does not show up, check the NMEA 2000 power and network supply and
termination.
LED will be on in normal operation

4.1.5 LinearBox
The Sailmon LinearBox is an interface for 3rd party linear sensors to be connected to
the E4 processor by means of the NMEA 2000 backbone. Up to 16 LinearBoxes can
be connected to a single E4 Processor. The linear box provides overvoltage and
electrostatic protection by means of galvanic isolation.
The E4 will measure linear inputs with an update rate of 4Hz allowing monitoring and
logging of all channels
Installation
This is a straightforward process.
The box is designed to be installed inside the hull. The preferred installation location is as
close to the sensor as possible. This will keep the analog wires between the sensor and the
LinearBox short. Please note that NMEA 2000 is designed so that you do not have to feed
analog wires across the boat, so keep sensor wires short and distribute your signals over the
NMEA 2000 bus.
After choosing a suitable installation
location, feed the sensor cable into the
left cable gland of the LinearBox and
connect the wires according to the
color scheme printed on the circuit
board.

5.1 system set ups
What are the minimum requirements of existing on board systems that Sailmon can work
with?
5.1.1 B&G
H3000
A H3000 CPU and fastnet network can
easily be Upgraded to an E4 processor
With the E4 it is possible to connect the
fastnet installation and retain the B&G
Displays.
A wind box will be needed and analog
transducers will need to be connected
with the use of a DST-2 to the E4 port 2
which is set to receive NMEA 0183.
.
SAILMON
Page 44
The Schematic below shows how the E4 can replace the H3000 CPU and still retain 20/20
displays and through hull transducers
Upgrade benefits:
- Reuse of existing transducers with use of an Actisense DST - 2
- Reuse of existing displays
- Wifi connectivity to stream data to any wifi enabled device
- Greatly improved calibration capabilities of existing sensors
- The ability to add Sailmon displays
For interfacing with fastnet displays, a GFD or FFD is still needed. Sailmon will receive and
send all data over the fastnet network but will be unable change display fields.
SAILMON
Page 45
H5000
Due to the H5000 use of the NMEA 2000 data format the E4 is a straightforward upgrade
from the B&G processor, resulting in greater usability and connectivity. All existing sensors
can be connected directly to the NMEA 2000 backbone or with the use of Sailmon interface
boxes.
Calibration and configuration is all completed using the Sailmon Navdesk tool
5.1.2 Garmin GNX displays
Due to the Garmin GNX displays use of NMEA 2000 data format they can be connected
directly to the NMEA 2000 backbone where the E4 processor can send data to the displays
as configured in the sailmon Navdesk
5.1.3 Raymarine
ST1:
Seatalk 1 is an older Raymarine protocol, The E4 processor is capable of converting this
data format via the Port I/0 connection. However, to be assured of a steady data flow we
recommend the use of a STng - St1 converter. With this device, Seatalk 1 is converted to
SeatalkNG and then connected to the NMEA 2000 backbone.
If this conversion is required, the following items have to be purchased:
Seatalk 1 - Seatalk NG converter.
this kit includes: converter, power cable, Stng drop cable, ST1 connection cable
Seatalkng to NMEA 2000 adapter
SAILMON
Page 46
Raymarine SeaTalk ng
Due to the SeaTalk NG’s use of the NMEA 2000 data format, the E4 is a simple upgrade,
gaining greater usability and connectivity. All exciting system sensors can be connected
directly to the NMEA 2000 backbone. Calibration and configuration is all completed through
the Sailmon Navdesk tool
Due to Raymarine custom connectors a STng - NMEA 2000 adapter cable will need to be
used.
5.1.4 Nexus
To upgrade an existing Nexus FXD instrument system a Garmin GND 10 will be needed to
convert the data to the NMEA 2000 protocol, this in turn can then be connected to the MNEA
2000 Backbone which is connected to the E4. Calibration and configuration is done through
the Sailmon Navdesk tool.

5.2 Troubleshooting
5.2.1 NMEA 2000
In the event the system is up and running, but no data is visible on the displays check the
NMEA bus has correct power
The E4 does not power the NMEA 2000 backbone it will need a separate power connection
Please see the image below to have a clear view of a test setup.
For this setup to work, some backbone changes have to be made:
● Look for the terminator which is farthest away from the power supply.
● Place a T - piece between this terminator and the backbone, reconnect the terminator
to this junction.
● Connect the modified NMEA 2000 cable to the T-piece.
● Test voltage (red and black wires from NMEA 2000 cable)
A range between 11.5VDC and 14.4VDC is acceptable.
A higher voltage may indicate a possible malfunction of the vessels charging system.
A lower voltages may indicate the presence of faulty connectors or / and a voltage drop in
the vessel's power supply.

FAQ.
General
Q: My E4 is working but my displays say connecting to server.
A: Make sure both displays, controlling device and E4 are connected to the same DHCP
server.
Q: They are connected to the same DHCP server but displays still say connecting to
server.
A: Make sure the connections in the SAILethernet are correctly connected, if you have
installed a junction box somewhere, ensure this has also been connected correctly.
Q. How do I connect my depth and speed transducers?
A. If they are not NMEA 2000 but analog, we can supply a Actisense DST-2 to convert the
signal to NMEA 0183.
Q. Can I connect a B&G 213 or VMHU?
A. Yes our WindBox converts the signal to 100hz NMEA 2000 wind sensors
Q. Can I connect a load cell?
A. Yes our Loadcell Box is a load cell amplifier that can interface with most 4 or 6 wire
load cells and send the signal to NMEA 2000.
Q. Can I connect any other sensors?
A. Yes with our Linear Box you can input 2, 0-5V sensors to measure any value you
would like.
Q. Does your system interface with any navigation software?
A. Yes, we can speak with plotters over the NMEA 2000 bus, Expedition in the
expedition format over UDP and Adrena over ump using NMEA 0183.
Q. What if I want to display some custom sentences?
A. We have 128 channels available to send any data string over UDP you would like,
please contact us for the user guide!

Fastnet
Q: I have installed the E4, and connected the fastnet cable but there is no signal nor is
there a light.
A: Ensure it has been cabled and setup correctly this includes red and black.
Q: I have checked that the connection is right, but still no light, any ideas?
A: Make sure port 2 is set to B&G Fastnet in the Sailmontool.
Q: I have tried all of the above but still no light, any more ideas?
A: Disconnect the power from the fastnet bus, and measure the resistor between green and
white, it should be 50 Ohms. If it reads 70 Ohms there is just one resistor, if it reads 30 Ohms
there are 2.
Q: Great the light now comes on! But I don't receive any data if I look in Navdesk
diagnostics.
A: Since Model E4 can work with or without the B&G H2000 and H3000 processor, fastnet output
is disabled as default. Make sure to enable it.
Q: I still have a B&G processor in the network and the numbers are all over the place, any
idea?
A: Make sure the fastnet output is disabled, you can do this through Navdesk.

No Network detected
Q: My E4 is working. On board is a Pepwave (or other kind of router) which is used as
a switch for the SAILethernet as well. I do not detect any network on smart devices.
A: Take the router out of the network. Then connect the SAILethernet to the E4 and check if
the displays work. If so, Sailmon works and the problem lies somewhere in the router.

Windbox
Q: The blue status LED does not light up.
A: Check the NMEA 2000 power supply and the termination resistors of the NMEA 2000 bus.
Q: The blue status LED blinks 5 times per second.
A: Check the sensor connection and the sensor cable for errors. In case all connections are
working, the MHU sensor is most likely damaged.
Q: I cannot adjust the MHU offset with my instrument system (other than Sailmon)
A: The Wind Box is designed to be integrated into a Sailmon system. It does not provide
direct offset features since Sailmon uses advanced calibration which is done in other parts
of the system. Contact Sailmon support if you plan to use the Wind Box for other instrument
systems.
Q: My wind instrument (other than Sailmon) hangs or gets stuck.
A: Since the Wind Box delivers wind data with a high update rate of 100Hz, this may be too
much for some instruments. Special software is available in this case, to solve this problem
contact the Sailmon support team.
Q: After a software update, my Wind Box does not work anymore.
A: To solve this issue please get in contact with our support team.
