problems. Another display that can be added to this tool is the Signal
(fields) module that can show selected signals for the CAN database,
covering the Application Layer of CAN/NMEA 2000.

Interfacing with the NMEA 2000 CAN bus
To connect the above tools to the NMEA 2000 data bus, several specialized connectors were utilized that are available from Warwick Control. For interfacing to the PC-based X-Analyser software, any Kvaser
CAN interface can be used. In the Warwick NMEA 2000 maintenance
kit, the Kvaser Leaf Light is used. Most Kvaser interfaces connect to the
USB on the PC, and connect to the CAN bus via a D9 connector. There
are Kvaser models that have the NMEA 2000 M12 connector option,
but if you are utilizing the standard D9 connection version, Warwick
Control offers a M12 to D9 adaptor cable.
For connecting the oscilloscope option, the PicoScope PC-based software is used. In the Warwick kit, the PicoScope model 2206B is used,
which is a USB/PC based oscilloscope interface. The software is supplied
by PicoScope. The two-channel interface is connected to the two CAN
wires on the NMEA 2000 CAN bus via a specialized M12 to dual BNC
connector supplied by Warwick Control.
Connecting the above devices to the NMEA 2000 Trunk Line is a
simple matter of adding a M12 T-connector at any point of the NMEA
2000 trunk line. These are easily acquired by many manufacturers. Fig.
9 reviews these options that are available in the Warwick Control NMEA
2000 maintenance kit.

Throughout this article we have covered the aspects of CAN and how
it maps into the NMEA 2000 standard. The article is meant to provide a
brief overview of CAN and NMEA 2000. MEJ

recommendations based on the findings of the
Beta Team testing to date. To maintain positive
momentum, a Virtual Private Network (VPN) has
been established so the Beta Team can continue to
interact and interoperate as if they were in an
actual room together. Hopefully this will facilitate
the delivery of final beta products.
The goal is to have another Beta Team face-to-face meeting in September to demonstrate the
interconnectivity and interoperability of all the
OneNet Draft Standard modules. Publication and
release of OneNet Version 1.000 is scheduled
before the end of 2017. Yet, that date is flexible
based on the final results of the Beta Team discoveries and findings and any subsequent technical
changes to the OneNet Standard that may be
