NMEA  2000  data  instance  (3)  may  be  used  when  multiple  Devices  are  installed.  For  example, 

 

“Inside  Humidity”  with  data  instance  0,  1,  2  may  mean  humidity  in  saloon  and  in  the  bow  and  aft 

cabins. Chart plotters with factory settings are usually able to show only one value with data instance 0,  

but manufacturers may supply dealers and professional installers by internal instruments to customize 

chart plotter screens. Please refer to your chart plotter manual before changing this setting.

Inside / outside (4) setting switches the transmitting type of measured data between inside (cabin, saloon) 

air temperature and humidity to outside (the boat) and vice versa. Actually, it changes only the type  

of transmitted data. The calculated dew point temperature is not affected by this setting because  

NMEA  2000  only  has  the  “Dew  Point  Temperature”  data  type.  This  can  cause  a  conflict  if  two  Devices 

 

are installed. In theory, this conflict can be solved by assigning different data instances (3) to the Devices 

or selecting a data source in the chart plotter or instrument display. But in practice many of modern chart 

plotters and instrumental displays have no such capabilities. In this case, you can leave only one source  

of dew point temperature in your network with the next setting.

Table 2. Data types in periodically transmitted messages

NMEA 2000 Message

Humidity

PGN 130313 Humidity

Note 1:

Dew point sent in separate message from air temperature

Settings (5) allows you to turn off a specific data type in the transmitted messages. For example, when 

humidity  is  turned  off,  a  message  with  PGN  130313  is  transmitted  with  a  “no  data  available”  value. 

 

And the same for air temperature. The only exception is for the dew point temperature. The Device will stop 

sending messages with dew point temperature if this data type is turned off.
