9: Fuel Pressure – This field indicates the pressure of the engine fuel in units of 1000

Pa.

10: Reserved – This field is reserved by NMEA; therefore, the J2K100 sets all bits to a

logic 1.

11: Engine Discrete Status 1 – This field indicates warning conditions of the engine with

the following bit assignments (value of 1 indicates warning present):

Bit 0: Check Engine

Bit 1: Over Temperature

Bit 2: Low Oil Pressure

Bit 3: Low Oil Level

Bit 4: Low Fuel Pressure

Bit 5: Low System Voltage

Bit 6: Low Coolant Level

Bit 7: Water Flow

Bit 8: Water in Fuel

Bit 9: Charge Indicator

Bit 10: Preheat Indicator

Bit 11: High Boost Pressure

Bit 12: Rev Limit Exceeded

Bit 13: EGR System

Bit 14: Throttle Position Sensor

Bit 15: Emergency Stop Mode

12: Engine Discrete Status 2 – This field indicates warning conditions of the engine with

the following bit assignments (value of 1 indicates warning present):

Bit 0: Warning Level 1

Bit 1: Warning Level 2

Bit 2: Power Reduction

Bit 3: Maintenance Needed

Bit 4: Engine Comm Error

Bit 5: Sub or Secondary Throttle

Bit 6: Neutral Start Protect

Bit 7: Engine Shutting Down

Bit 8-15: These bits are reserved and should be masked when read

13: Percent Engine Load – This field indicates the percent load of the engine in units of 1

percent.

14: Percent Engine Torque – This field indicates the percent torque of the engine in units

of 1 percent.

PGN 127498 – Engine Parameters, Static

The J2K100 uses this PGN to transmit unchanging engine data.

Field 1: Engine Instance – This field indicates the particular engine for which this data

applies. A single engine will have an instance of 0. Engines in multi-engine boats will

be numbered starting at 0 at the bow of the boat incrementing to n going in towards

the stern of the boat. For engines at the same distance from the bow are stern, the
