Default Garmin 740s & SH GX2100 Matrix AIS Questions

Ok, I finally got them both wired up to play together on the workbench and eventually saw an AIS target (yaayyy!). Then, I was almost going to ask on here how to turn off the AIS function on the 740s when I want, but managed to find the AIS on/off Ďbuttoní buried down in one of the Configure Menus.
So, I installed them in the boat but now am getting no targets at all (booo!) and I donít know whether there just isnít anything out there right now (middle Keys), or if I knocked a wire loose or something. Guess Iíll sit here and wait and watch it for awhile.

While I was waiting and watching, it brought up two questions...
1) When the 740s sees an AIS target and I acknowledge it, should that target-alarm keep popping back up every so often? Not sure if it loses contact momentarily and then sounds the alarm all over again, or if itís supposed to keep cycling or what, but when I had it on the bench it was driving me nuts. Iím not talking about turning the function off completely, but simply letting it know that I am aware of a target and wish to cancel that specific alert.
2) If I turn off the AIS function completely in the 740s (in the Configure menu), will the GX2100 still plot the AIS target in its display or does it stop as well?

Any help would be appreciated.

1. If it's a hazard vessel yes

2. AIS is a prouct of the radio not the chartplotter. You can turn AIS off on the 740 and the radio will display them as long as your radio is set to the AIS display. You will continue to get alerts from your radio. You can set hazard vessel protocols both on the radio and chartblotter. You can turn alerts off.

Well, duh! That was embarrassing of me. Of course the 2100 is what receives the AIS signal and pipes it to the 740s, and not the other way around. Guess I was so focused on seeing a target that I forgot how it got there.

Many thanks, Tom! As always, you’re a veritable fountain of information.
