2.3 NX2/NEXUS PRODUCT TYPE WITH POSSIBLE
CATEGORIES
Product
There are basically 4 different Marine electronic product types, where some of the
product types also include NMEA 0183 input & output.
• NEXUS Network-Manager
• NEXUS Network-Repeater (talk & listen)
• NEXUS Network-Repeater (listen only)
• Standalone instruments with no NEXUS Network
Product Type
The most advanced type is the NEXUS Network-Manager, which is needed to
establish and operate a NEXUS Network. The Server will automatically be the
NEXUS Network-Manager when installed, but other units may be used as a
NEXUS Network-Manager. See further details in the NEXUS Network
specification, appendix A.
Possible Category
Each category represents one or more core functions given from a transducer
(i.e. wind- speed wind angle) or calculated by an instrument (GPS navigational
data). Only one category may be activated as a category master even if multiple
category instruments are available in the NEXUS Network.
Example 1: The Server may give away the Wind category to the Wind Data
instrument on request from the configuration set-up. It is therefore very important
to configure the Network so it corresponds to where the transducers or the
”category’s” are connected or used.
Example 2:
Where two Wind Data instruments are installed, only one may be
set-up to be the Wind category master, the other must be set to Repeater mode.
Also, if the Server is missing, the Wind Data instrument with category Wind will
become the NEXUS Network Manager. For further information, read the NEXUS
Network specification, appendix A.
