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. 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. GNSS Configuration The GPS and GLONASS options may be enabled simultaneously, or individually. Generally, GPS offers the highest accuracy, but in certain circumstances a better fix may be achieved with both or only GLONASS enabled. 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. | 5
