-No error messages.
-I did not see any incoming messages in the activity monitor. All modules work with the Mini Controller in multiple outlets. I tried the CM11A in the same outlets and the activity monitor just shows it sending a signal over and over. One thing I did notice is that the activity monitor does show the wrong address some of the time but not all of the time. I have all the modules set to house code D. Sometimes when trying to turn on D1 I notice the activity monitor showing A1 instead of D1. A computer restart seems to fix that at least temporarily. I would try to uninstall and reinstall but I'm not seeing an uninstaller and just deleting the AHP folder seems to leave a lot of info behind on the computer that is still in AHP when I install it again.
-I am using an adapter. It's this one http://www.byterunner.com/byterunner/product_name=Y-105/user-id=/password=/exchange=/exact_match=exact which was reccomended by dhouston. I did however install the driver from a website not the included miniCD since I have a slot load drive. I suppose I could have the wrong driver, I will have to investigate that when I get home.
I know this is a dumb question, but are you sure you set AHP to use the same COM port that the USB-to-Serial adapter is providing?
Are the com port settings correct in Windows (Baud Rate: 4,800bps; Parity: None; Data Bits: 8; Stop Bits: 1)?
Does AHP give you a warning at startup that it can't find an interface plugged in?
Have you already tried unplugging the CM11A, removing the batteries, waiting a minute, putting the batteries back in, and plugging it back in?
Does the Windows Device Manager see the CM11A at all? (I don't know if it is supposed to or not - I haven't played with a CM11A with AHP yet)
