Position Update Position update rate may be adjusted to suit your vessel and to minimize unnecessary NMEA 2000 data traffic. For high speed vessels, the maximum update rate will be desired for measuring performance to the highest possible accuracy. On slower vessels, and large networks with a lot of network traffic, it may be preferable to reduce the network load. COG/SOG Filter Averages COG/SOG data to smooth out displayed values. The best setting will depend on the type of vessel and user preference. Configure/Offset Offset may be applied to correct for small errors seen in the orientation relative to the bow of the vessel. This would typically be the result of the antenna not being physically 100% parallel with the center line of the vessel. To determine a correction value, a reliable hand bearing or fixed magnetic compass should be used for reference. ¼¼ NOTE: Ensure calibration of compass is completed prior to adjusting the offset. Instance If more than one device of the same type exists in the network, the instance number may be changed to a unique number to allow easier identification. You also can disable the heading sensor on the Point 1 antenna by changing the instance value. | 9
