Engine 
This will force the GPS100 to restart its GPS engine without performing a full reset of the unit. 

 

Field  1:  Complex Command Group Function Code (8 bits) – set this field’s value to 0x01, 

which denotes a command PGN 

 

2:  Commanded PGN (24 bits) – set this field’s value to 126720, which denotes the 

Maretron proprietary PGN 

 

3:  Priority Setting (4 bits) – set this field’s value to 0x8, which indicates to leave priority 

settings unchanged 

 

4:  Reserved (4 bits) – set this field’s value to 0xF, which is the value for a reserved field 

of this size 

 

5:  Number of Pairs of Commanded Parameters to Follow (8 bits) – set this field’s value 

to 0x4, indicating that four parameters will follow 

 

6:  Number of First Commanded Parameter (8 bits) – set this field’s value to 0x1 

 

7:  Maretron Vendor ID and Industry Code (16 bits) – set this field’s value to 0x9889 

 

8:  Number of Second Commanded Parameter (8 bits) – set this field’s value to 0x02 

 

9:  Product Code (16 bits) – set this field’s value to 0x6F0, which is the NMEA 2000

® 

product code for the GPS100. 

 

10:  Number of Third Commanded Parameter (8 bits) – set this field’s value to 0x03 

 

11:  Software Code (16 bits) – set this field’s value to 0x0001, which is the identifier for 

this version of the Maretron proprietary protocol 

 

12:  Maretron Command (8 bits) – set this field’s value to 0x30, which will force the GPS 

Engine to restart as selected by the following field. 

 

13:  Restart mode (8 bits) – set this field’s value to select the restart mode, 0=Factory 

restart, 1=Cold start.
