AFS 4500 and Autopilot

[wnplt]

Hi guys... I have an AF 4500 and trutrak autopilot. I’m trying to get an autopilot audible alert when pushing the disconnect on the stick. I tried input user 1 but the problem is unless I hold the switch for a second or two the AF 4500 doesn’t recognize it and alert me. Usually when I disconnect or it gets bumped it’s a quick push and the AF 4500 doesn’t see the push. I heard another way is to wire the AP Serial Out to the AF Serial in. I added that to the admin setting in the af 4500 and get the “Engage” along the bottom. It used to say FD/HITs but that has been moved to another page. If I make this connection how can I expect the AP to be engaged and disengaged in the af 4500? Will the stick disconnect switch still show up with an audible alert. Bottom line is I want an alert when the stick disconnect is pushed intentionally or unintentionally.

Thanks
