4.2 Nexus databus introduction and user policy
Introduction:
The Nexus data bus is a multi talker multi receiver data bus specially designed for
marine navigation applications. It utilises the RS485 standard with up to 32 senders
and/or receivers to form a Local Area Network. Data is transmitted synchronously with
1 start-bit, 8-data-bits, 1 parity-bit, two stop-bits in 9600 baud.
User policy:
The Nexus data bus is open for new users and applications without the a licence or a
licence fee. The data bus is, however, the property of the manufacturer, which means
the specification must be followed in order to protect the manufacturer’s commitments
to the Nexus data bus performance and safety.
For most PC-applications, the full duplex interface (Art. No. 21248), will be a very
useful tool for monitoring real time data, to edit and store waypoints to PC-file or to
Server and/or to the Nexus GPS. The interface is supplied with a cable for connection
from PC to the Server or Nexus instruments and/or the Nexus GPS. A 9-pole D-sub
connector is connected to the RS232 port on the PC.
