Advanced Options menu 

The Engine Interface Advanced Options menu contains three categories: 

Instance, Restore Defaults and Reset Trim Calibration. 

 

The Instance command is intended for use only by experienced NMEA 2000 

network technicians. Instance allows network technicians to resolve certain 

electronic probe conflicts. This is most likely to occur if the network includes 

LMF-200 or LMF-400 digital gauges, which support the display of fewer elec-

tronic probes than your GPS or sonar/GPS unit. If you want to use your unit in 

a network including one of these digital gauges, you may need to consult cus-

tomer service. You should never need this command if you are connecting your 

unit to a network with similar display units and/or a series of electronic 

probes.  

The Restore Defaults command allows you to reset an individual engine 

interface's settings to factory defaults. If, for example, you execute the Re-

store Defaults command from your Port Engine Interface Advanced Options 

menu, only the settings for the Port Engine Interface will be reset to factory 

defaults. Other engine interfaces on the network will not be affected.
