In order to support “plug-and-play” operation, if N2KView receives the same data
from multiple devices that have the same device instance programmed, it will
“lock on” to the first unit it receives data from until either 1) it stops receiving data
from the first unit, in which case it will switch to the second unit, or 2) it starts
receiving data from another unit with higher Priority, in which case it will transmit
the data from that unit.
8.3.2 Data Source Types
The NMEA 2000 standard provides for the transmission of data from similar
devices, but for different sources. For example, the NMEA 2000 standard
supports six different types of fluid tanks: Fuel, Oil, Live Well, Fresh Water,
Waste Water, and Black Water. It further supports up to sixteen tanks of each of
these types. It is the responsibility of the person installing the NMEA 2000
system to ensure that each tank level sender is programmed with the appropriate
fluid type and tank instance.
8.3.3 Sensor Selection
Of course, one key to making the N2KView System work is making sure that your
NMEA 2000 network has the proper sensors to provide the information you wish
to monitor using N2KView. Section 9.6 on page 162 contains a listing of all of
the data types that can be monitored using N2KView.
To see what Maretron sensors provide data for each of the listed data types, you
may download the latest Maretron Capability Matrix from the Knowledge Base on
the Maretron website.
