IV.4 Connection to SmartCraft Engines
The SmartCraft protocol is used in Mercury and MerCruiser engines, and differs from J1939 and Volvo
Penta EVC protocols and requires configuration of the Device. The Gateway can be connected to a 10-pin
SmartCraft connector with the adaptor Y-cable, available on our website.
The Device supports up to four SmartCraft engines on a network. A list of the supported data and warnings
is available in Appendix H. Note that the number of NMEA 2000 engine warnings is limited and cannot
cover all SmartCraft warning and error codes. To activate the SmartCraft protocol support, the V.35 setting
must be set to ON (SMARTCRAFT=ON).
If you get a limited set of data in NMEA 2000, try to change the value of the SMARTCRAFT setting
to HANDSHAKE (usually this is required on old engines with analog gauges).
Engines in a SmartCraft network has numbers from 0 to 3 and the transmission has no dedicated address.
In the Gateway settings, engine numbers must be used instead of J1939 engine or transmission addresses.
Each engine may have two fuel tanks (port and starboard).
The recommended configuration for a vessel with four engines, one battery and four fuel tanks connected
to engine #0 (port) and engine #1 (centerline port) is:
SMARTCRAFT=ON
ENGINE_0=0
ENGINE_1=1
ENGINE_2=2
ENGINE_3=3
NMEA_ALTERNATOR=KEYSWITCH
TRANSMISSION_0=0
TRANSMISSION_1=1
TRANSMISSION_2=2
TRANSMISSION_3=3
FUEL_0=0,PORT
FUEL_1=0,STARBOARD
FUEL_2=1,PORT
