CM15A Driver

[doug]

I have been using my CM15A and all was
functioning well.  I recently plugged the
CM15A into my USB port to make changes to
my timers, and my system will not recognize
the CM15A.  Can anybody help???

Not sure of your setup but does your USB cable run along side any power cables? It may be that if the light is making a lot of noise, that the noise is being picked up by the USB cable if it runs parallel with a power cable. This shouldn't effect it but may indicate you have a bad or poor USB cable itself.

You can try to relocate the cable to the CM15A to see if this helps. I run 2 USB extensions on my controller and every now and then the AHP software pops up an error saying it lost communications. and asks if I want to download to the controller. Also inspect the USB plug ends for any damage. Be sure to unplug them and then plug them back in. Could be a dirty or bad plug connection.

I get that "every now and then the AHP software pops up an error saying it lost communications and asks if I want to download to the controller" message too.

I think it's AHP that looses the communications all by itself , not the USB cable. My CM15A is on a cable all its own and the cable is not the clear one that comes with it. I didn't like it (it seemed too lightweight) and replaced it.

The message may be a probgramming bug.

You may be right Dan, seems others have posted the same thing. I did notice however that I got the error less when I didn't have the USB extensions. However the benefits to getting the CM15A away from the computer and to higher ground is worth the occasional error.
