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 Link-
Local 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 non-
compliant devices) use the RS-232 protocol which uses a single signal wire and
a ground connection.

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.
