these are for the AIS plug in unit to portray various target vessels around you and decide if they are on a collision couse or not basically. It allows you to set the port to use the AIS unit.
You can set the various limits as to whether or not they are still a thret after a certain number of miles and it can alert you with sound etc. The bottom option is for the anchor portion letting you force it to ignore a solid target, more or less.
The COG means course over ground and it allows the option of displaying that intended course on your display or not.
I'm sure the other members of the group can shed a more detailed light on these functions and options since I'm not hooked into the AIS stuff with my boat.
