I'm not getting any communication between my PC and my interface. None of my com ports are being recognized and I dont know why. I am unable to download any time events for my lights in Active Home. always worked before, but now, nothing. Any help would be appreciated. Thanks.

Sometimes it helps to disconnect the USB connection, unplug the CM15A and remove the batteries.  Then reassemble and replug and try again.

I believe the OP has the cm11 with Active Home. (comm ports)

What does the Device Manager show for Comm Ports.
Are you using Windows XP? XP and some motherboards give comm port problems with AH.

Yup!  You're correct.  I should have caught that.

I have the CM11...that is correct...I've tried taking out the batteries, disconnecting the CM11...all for not. I've got something wrong because when I re-boot I get an error message on my desktop saying "Invalid Com port Selected".....That is on start up. Something is causing my grief and I dont know what it is!

What does Device Manager show in the comm port tab?

[hawk1]

Might want to check your bios.  If your mb battery went dead it might have automatically changed the comm ports to the defaults.

Where might I find the device manager??? I'm running XP to answer a question above.

Click start, RIGHT click "My computer", LEFT click Properties, LEFT click Hardware, LEFT click Device Manager. In device manager double LEFT click ports.  Then double LEFT click what ever port you want to look at.

I went into device manager as instructed. The only com port i see is com1 and it tells me that it is working properly. When I go into AH to test communications, it shows me connected to com 2...i click com 1 to test and it gives me a failure to connect and reverts back to com2 again???

[hawk1]

How many comm ports do you actually have?  If you have 2 then my previous post would come into play. (bios)  If you have 2 physical ports, have you tried the other one?

I have one com port that the interface will plug into....I just downloaded the version 1.42 to my laptop and installed it. As soon as I open AH on the lap top, not having the interface connected to it, It opens and gives me an error message" Invalid com port selected" I'm confused now! I appreciate the help.

What version software on the Laptop?
Did you try a different comm port choice in AH on the Laptop. Maybe Comm1 is used by a internal modem or a similar device.
