Factory settings (from x=0 to 7): 0, 1, OFF, OFF, OFF, OFF, OFF, OFF
Batteries on the NMEA 2000 network have identifiers analogous to engines. The value, though,
is not related to the location or purpose of the battery.
For example, on a sailing yacht with a single engine, data on the service battery will be transferred
by a special sensor on the NMEA 2000 network. The service battery has an identifier of 0
on the NMEA 2000 network. The engine has an address of 0 on the J1939 network and provides data about
the ignition (keyswitch) battery. Then the correct configuration file would look like this:
ENGINE_0=0
NMEA_BATTERY=KEYSWITCH
BATTERY_0=OFF
BATTERY_1=0
4. NMEA_ALTERNATOR=[KEYSWITCH | CHARGING | POWER_INPUT | OFF]
Factory setting: KEYSWITCH
Along with data about the current parameters of the engine’s operation, the Device can provide data
about the voltage potential of the alternator of the given engine. The possible values of the parameter
are described in NMEA_BATTERY. The data for the engine will be transferred only if the list
of BATTERY_x parameters contains a battery with the same J1939 address as the engine.
5. FUEL=[DIESEL | GASOLINE | OFF]
Factory setting: DIESEL
The OFF value completely blocks sending of data about the level of fuel in the tanks. The values DIESEL
and GASOLINE are used when sending message about the level of fuel to specify the fuel type.
Note that many chart plotters cannot display gasoline tanks; use DIESEL as the value if there
are compatibility issues.
