Nemo Gateway 1

Introduction

Thank you for purchasing a Rose Point Navigation Systems Nemo Gateway. The
Nemo Gateway is a bridge between the NMEA 0183, NMEA 0183-HS, NMEA
2000 marine electronic device network communication standards and your
shipboard Ethernet-compatible navigation systems and devices (e.g. computers
running Coastal Explorer/Rose Point ECS, tablets, phones).

The Nemo Gateway has been certified by the NMEA to meet the NMEA 2000
standard and conforms to the NMEA 0183 and NMEA 0183-HS standards. Due
to the technical nature and complexity of these standards it is recommended
the Nemo Gateway is installed by an NMEA certified installer.

Device Connectivity

Nemo Gateway 3

Gateway Connections

POWER

The Nemo Gateway may be powered by 8 – 32 volts DC, negative ground. If an
AC to DC adapter is being used, it needs to be a 12V 2A adapter, and must be
connected to an uninterrupted power supply. The Nemo Gateway needs to be
protected with an inline 3-amp fast acting fuse or circuit breaker.

Recommendation: The power source should be independent of the vessels
starting battery system.

ETHERNET

Connect an Ethernet cable between the ETHERNET port on the Nemo Gateway
and your PC or network (router, switch or hub). If connecting the Nemo
Gateway to your network, your PC(s) may connect to the same network via
Ethernet or Wi-Fi. If utilizing Wi-Fi, your router or access point would provide
the Wi-Fi connectivity.

When connecting to an existing network the Nemo Gateway should be able to
operate without additional configuration, either by acquiring a DHCP or Link­Local IP address. Changes to the configuration can be made following the steps
in section Device Configuration of this manual.

The Nemo Gateway can output NMEA 0183 information over UDP, allowing
multiple devices on the same network to receive data simultaneously.

Recommendation: All devices critical to the navigation system should use a
wired Ethernet connection.

NMEA 2000

The Nemo Gateway has been certified by the NMEA to meet version 3.10 of the
NMEA 2000 standard.

The Nemo Gateway has a single NMEA 2000 terminal used to connect it to the
bus with a drop cable. Ensure that the drop cable used to connect to the NMEA
2000 backbone is no more than 6 meters in length.

4 Rose Point Navigation Systems

Accessory Port (ACCY)

The ACCY port is reserved for future use. Please do not plug any devices into
the ACCY port unless specifically approved by Rose Point Navigation Systems.
Please refer to our website for updates regarding the use of this port.

NMEA 0183

The Nemo Gateway conforms to the NMEA 0183 and NMEA 0183-HS marine
electronic device network communication standard. All NMEA 0183 ports are
capable of communicating in NMEA 0183 (4800 baud) and NMEA 0183-HS
(38,400 baud) modes via two talker ports and four listener ports.

NMEA 0183 and NMEA 0183-HS standards define device ports as either Talker
or Listener. A Talker is a port on a device (e.g. GPS) that is transmitting
information. A Listener is a port on a device (e.g. chart plotter) that is receiving
information. Some devices are capable of being both a Talker and a Listener, for
example an AIS transponder or chart plotter.

Common talker devices include GPS’s, depth sounders, water speed indicators,
compasses, and wind indicators. Common listener devices include: AIS
transceivers, autopilots and chart plotters. Most of the common listener devices
mentioned will also have Talker ports

Note: A Talker may be connected in parallel to up to 10 Listeners, while a
Listener may only connect to a single Talker.

Note: Talker 1 and Listener 1 operate at the same baud rate, but are otherwise
independent. Talker 2 and Listener 2 can also only have one baud rate, but are
otherwise independent.

Example:

Nemo Port 1 Talker - Connect autopilot ("Talking to AP")
Nemo Port 1 Listener - Connect GPS device ("Listening to GPS")
Baud Rate set to 4,800 for Nemo Port 1 – This setting applies to both parts of
the port (Autopilot and GPS)

When using NMEA 0183-HS, a three conductor, shielded cable is to be used and
requires two connections to be made in addition to the A and B wires used in
the NMEA 0183 protocol. These additional connections are a common ground

Nemo Gateway 5

line (C) and shield (S). The ground line (C) is connected to both devices while the
shield (S) is only connected to the Talker. (See page 13)

Default port configuration

The following table describes the default port configuration. These defaults may
be adjusted in Rose Point ECS or Coastal Explorer or the companion app.

Changes to the configuration can be made by following the steps in section

Device Configuration of this manual.

Port Number

Protocol

Baud Rate

1

NMEA 0183-HS

38,400 baud

2,3,4

NMEA 0183

4800 baud

Typically, an AIS transponder would be connected to port 1, while other NMEA
0183 devices should be connected to ports 2, 3 and 4. If you are not connecting
an AIS or other NMEA 0183-HS device you may change the configuration and
use port 1 for a NMEA 0183 device.

Automatic Protocol (Baud Rate) Detection

The Nemo Gateway is capable of automatically detecting the protocol (baud
rate) of devices connected to the NMEA 0183 and NMEA 0183-HS ports. This
feature is enabled within Rose Point ECS, Coastal Explorer or via the Nemo
Gateway companion app (available on iOS or Android).

NMEA 0183 Compatibility

The Nemo Gateway conforms to version 4.10 of the NMEA 0183 standard and is
compatible with older versions.

Note: Current versions of the standard require use of differential pair wiring for
communication via the RS-422 protocol while older versions (and non­compliant devices) use the RS-232 protocol which uses a single signal wire and
a ground connection.

6 Rose Point Navigation Systems

The documentation for some devices may reference the NMEA 0183 and NMEA
0183-HS connections in different ways, please use the following pages to
identify how to connect the Nemo Gateway to other devices.

If it is unclear how to connect your NMEA compatible device to the Nemo
Gateway please contact the manufacture of the connecting device for additional
support. See the “Sample Wiring” section to see how sensors should be
connected to the Nemo Gateway. Additional sample wiring schematics are
available on the support page at

NMEA 0183 / NMEA 0183-HS Listeners

The four differential opto-isolated three terminal listener ports conform to the
NMEA 0183 and NMEA 0183-HS marine electronic device network
communication standard. These ports are capable of interfacing with most fully
and partially compliant devices that are transmitting any properly formed
sentences. Only NMEA 0183 and NMEA 0183-HS devices are to be connected to
these ports.

The Nemo Gateway will receive all properly formed NMEA 0183 and NMEA
0183-HS sentences.

Each listener port is isolated from all other listener ports. Each listener is
designed for operation with a minimum differential input voltage of 2.0 Volts

and shall not take more than 2.0 mA from the line at that voltage.

The listener circuit consists of an Altec PHP03-3.81 connector followed by a 240
ohm resister on the A line followed by isolation and protection circuitry.

NMEA 0183 / NMEA 0183-HS Talkers

The two differential four-terminal talker ports conform to the NMEA 0183 and
NMEA 0183-HS marine electronic device network communication standard.
These ports are capable of interfacing with most fully and partially compliant
devices transmitting any properly formed sentences. Only NMEA 0183 and
NMEA 0183-HS devices are to be connected to these ports.

Nemo Gateway 7

The Nemo Gateway is capable of sending all properly formed NMEA 0183 and
NMEA 0183-HS sentences.

Each talker port is capable of driving a load of 50 mA using a 5V differential pair.
The circuit is composed of a UA9638 driver connected to an Altec PHP04-3.81
terminal.

Sensors

The Nemo Gateway is capable of interpreting NMEA data being processed
through its data ports. This allows the Nemo Gateway to distinguish between
devices and assign priorities to sensors.

When the Nemo is generating NMEA data using "Auto" as the source (see
"Advanced Port Output"), having properly prioritized sensors will guarantee that
the Nemo is listening to and generating data from the appropriate sensors.

Nemo Gateway 17

Priorities may be set for each class (e.g. Position, Speed, Depth, etc.) of data. By
default, the priorities are chosen by the order the devices are discovered; the
first – highest priority, the last – lowest priority. To change the priority, select
Sensors > Sensor Class > Edit button, and drag the three-bar-icon up and down
to rearrange the order (top - highest, bottom – lowest).

Individual sensors can also be enabled/disabled in this menu.

Advanced Port Output

Please refer to our Nemo Gateway Configuration Guide online for the most
current configuration walkthroughs. The device’s configuration interface is
subject to change without notice.

Each port that is capable of outputting data will have a “Talker Options” section.

Repeating Data

The UDP and NMEA 0183 ports can repeat data received on other ports of the
same data format (NMEA 0183). Each source may be toggled On/Off
individually.

To configure data repetition options:

Port (UDP/NMEA 0183) > Talker Options > Repeating > Edit

Note: When possible, the Nemo Gateway should be set up to generate all
outgoing data. The ability to repeat data being received from other NMEA 0183
ports is designed to output sentences that the Nemo Gateway cannot parse or
generate on its own.
