I have 2 Bobcat T's in my system. From time to time I notice param 5 changes from 128 on both units to something else. I'm not certain if this is happening simultaneously or not.

On a (perhaps) related note, from time to time my Commstar 308 quits transmitting or receiving RS232. Unplugging the unit and plugging it back in usually restores communications.

Maybe this thread belongs under "General HA" as I'm wondering if brief power outages or maybe even voltage spikes cause these problems. I'm wondering if a power conditioner/back up power supply might be in order.

Thanks, Chris

Power spikes could produce this kind of problem. Assuming you're running with ac wall warts, one thing you could try (if you have a 12 vdc power supply available) would be to power the modules with dc and put filter capacitors across the power lines near the modules that are located at some distance from the power supply.
