I've got a H2CNTRIO where one of the channels starts to count on its own with the machine stopped. If you power it down and pull it out of the rack and re-seat it, it works fine for about an hour then the counting starts. I replaced the card and the problem doesn't happen (at least not for the past day). The customer never utilized that counting channel until now, so I don't know if the problem was always there or just appeared. I've installed about 30 of these in these machines over the past 7 year and never had one of them go bad until now. Its only about 3-4 years old. Whats the warranty on the card?
