13.2 Nexus Network specification
The Nexus Network is a high performance, non-collision multi-talker, multi-receiver data
bus, specially designed for marine navigation applications. The most important features
are the high update rate, fast response times, very low data latency (25ms) and very
high data security even at long distances. Another important feature is that data transfer
efficiency will not degrade even when used in large and complex systems. It utilises the
RS485 standard with up to 32 senders and/or receivers to form a Local Area Network.
Data is transmitted asynchronously with 1 start-bit, 8-data-bits, 1 parity-bit, two stop-bits
in 9600 baud.
The link between Nexus Network and your PC-application is the PC interface FD (Full
Duplex) / NMEA (Art. No. 21248-1). This is supplied with a 9-pole D-sub connector on a
1m (3.3 ft) cable for the RS232 PC port. The PC interface is a useful tool to monitor and
log real time data, or when editing waypoints to/from PC-file or to/from Nexus Network.
For users who writes there own software, please see our web-site where you find the
Nexus application notes.
13.3 Accessories
13.3.1 Autopilot instrument
Additional Autopilot instruments (Art. No. 20445-5) may be added. They are connected
in a "daisy chain" fashion from one to the other, matching colours on terminals. Control
may be transferred from one instrument to another by simply pressing any pushbuttons
(except the OFF push-button) on the instrument where active control is desired. All
other inactive instruments will display the same information as the active instrument,
however in the lower display the text "passive" will blink once every seven seconds.
13.3.2 Nexus Remote Control instrument
The Remote Control instrument (Art. No. 21210) is an instrument in itself that can be
set in either Autopilot mode to be used as an Autopilot instrument, or Instrument mode
displaying all information on the Nexus Network. Further it can be used as a remote
control for all instruments connected to the Network. It is the ultimate Nexus instrument!
13.3.3 Nexus analog Rudder Angle indication instrument
The analog Rudder Angle instrument (Art. No. 20550-9) indicates the rudder angle (50
°
- 0 - 50
°
). This instrument is connected on the Nexus data bus cable as per colour
codes.
13.3.4 Nexus Multi Control instrument with Server
The Nexus Server is the heart of the Nexus Network to which transducers for speed,
depth, wind, compass and navigators are connected. The Multi Control is a Multi
function instrument that displays a main and a sub-function, grouped into 4 pages for
speed, depth navigation and wind information. The Multi Control instrument and the
Server are the building components of the Nexus Network.
