Position update rate may be adjusted (1Hz, 5Hz or 10Hz) 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.
Compass Oset
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.
¼ 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.
Disabling the heading sensor
Set the Point-1 instance value to 001 to disable the heading sensor.
This is useful when more than one Point 1 antenna is installed on
the same network and you only want to receive data from one of
the heading sensors.
¼ NOTE: When the Point-1 detects
another heading source in the
network, it will automatically disable its
own heading output in preference of
the other source.
