14.2 Nexus Network 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 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 NX2 GPS. The interface is supplied with a cable for connection from PC to the Server or NX2 instruments and/or the NX2 GPS. A 9- pole D-sub connector is connected to the RS232 port on the PC.
