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 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. 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. ¼¼ 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. 108 | Point 1 antenna | Lowrance HDS Gen2 Touch

Point 1 antenna |
Lowrance HDS Gen2 Touch
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 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.
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.
