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.
