System architecture
This section explains how the NSE connects to other devices as part of a system. The
NSE has a highly scalable system architecture. A system can consist of a basic stand
alone chart plotter, or expand to a networked, multi-display system connected to a wide
range of accessories.
The system architecture is modular with a wide range of peripherals and accessories
that can be connected to SimNet or NMEA2000 devices such as instrument systems,
AIS, GPS and heading sensor to Ethernet devices such as Radar and Echosounder. For
multi display installations the system can be set up to be truly masterless, i.e. have no
dependency on other displays being powered on.
A NSE display can connect to other devices in the system by Ethernet, SimNet /
NMEA2000 or NMEA0183.
A system can have:
• between one and six displays, The displays can be any mix of NSE8, NSE12, and NSO.
Also, up to two NSS may be included.
• two radars
• three Navico echosounder modules
Networking, Data Interfacing
The NSE system can use three data networks. SimNet (NMEA2000), Ethernet and
NMEA0183.
SimNet / NMEA 2000
• SimNet is Simrad’s proprietary CAN bus network for transfer of navigation data such
as wind, Position, AIS, etc between all SimNet or NMEA2000 devices on a SimNet/
NMEA2000 network.
• SimNet is lower bandwidth than the Ethernet network, but is 50 times faster than
NMEA0183
Ethernet: (NETWORK ports)
• NSE uses an Ethernet network for the transfer of high bandwidth data between other
NSE displays and from network modules such as Radar, Echosounder and Weather
module
• Each NSE display has three Ethernet network ports. An optional 5 port expansion port
is available. (Recommended for multiple NSE displays)
• Ethernet does not transfer navigation data such as position, heading etc. This is
handled either by SimNet and or NMEA 0183. However navigation and display settings
are synchronized over Ethernet
NMEA0183
• NMEA0183 is a point to point connection. Each NSE display has one NMEA0183 port
using RS422 protocol. Each display can output to one NMEA0183 “Listener” and
receive from one NMEA0183 “Talker”.
