AMX Jandy Module..

I usually write my own code but due to being in a pinch I used the Jandy Pool control module that AMX has written. Over the last month or so the Jandy Aqualink RS has been replaced once and the new one still ocasionally locks up. AMX will still be sending the polling commands every 3 seconds but the Aqualink does not respond until power is removed and put back. Tech support at Jandy thinks the unit could possibly have a loose power connector causing intermittent power outages and by reseting the power to the unit it is coming back online. Anyway, I am trying to determine whether there is a programming issue or an installation issue and of coarse I am programming this remotely and cannot go onsite to verify what the tech is telling me. Anyone out there using the same module and having problems?
I have a home-grown module that does the same. I cry "bull" on the Jandy people - it's a flaw in the product. My module has a timeline that fires a relay, resetting the Jandy interface if it doesn't hear from it in the span of a minute. Someone at tech support there told me I could also reset it by asserting one of the comm lines (DTR, maybe?), but I never got around to it, the relays worked.
I also had a jandy RS module go MIA. It ran for a while and then died. It was replaced and everything was fine - for a while.
It died again and Jandy replaced it again. Then it died after several months.
The pool people were going to bring a replacement but it never happened.
Feedback from Jandy was they seemed to have identified a power issue on board for the pool control system and it was, in effect, killing the RS unit.
Our client basically gave up and turns the jacuzzi on with the pool controller - not the AMX TP. Unfortunately, the pool controller was a nice source of temperature data for the TP home page.
