◆

struct { ... } tNMEA2000::tDeviceInformation::tUnionDeviceInformation::@1

Structure for device information.

◆ DeviceClass

unsigned char tNMEA2000::tDeviceInformation::tUnionDeviceInformation::DeviceClass

Device class.

see for Details: NMEA2000 Device and Function Codes

Definition at line 331 of file NMEA2000.h.

◆ DeviceFunction

unsigned char tNMEA2000::tDeviceInformation::tUnionDeviceInformation::DeviceFunction

Device function code.

see for Details: NMEA2000 Device and Function Codes

Definition at line 325 of file NMEA2000.h.

◆ DeviceInstance

unsigned char tNMEA2000::tDeviceInformation::tUnionDeviceInformation::DeviceInstance

Device instance number.

Definition at line 319 of file NMEA2000.h.

◆ IndustryGroupAndSystemInstance

unsigned char tNMEA2000::tDeviceInformation::tUnionDeviceInformation::IndustryGroupAndSystemInstance

Industry Group and System Instance (each 4bits)

I found document: http://www.novatel.com/assets/Documents/Bulletins/apn050.pdf it says about next fields:
The System Instance Field can be utilized to facilitate multiple NMEA 2000 networks on these larger marine platforms. NMEA 2000 devices behind a bridge, router, gateway, or as part of some network segment could all indicate this by use and application of the System Instance Field. DeviceInstance and SystemInstance fields can be now changed by function SetDeviceInformationInstances or by NMEA 2000 group function. Group function handling is build in the library.
