DVX Max Temperature Reading

DigiMe

All,

I know the operating temperature of the DVX-3150 is between 0º C to 40º C (32º F to 104º F).
But does anyone know what is the max temperature it will read before no longer sending back any level event on level 8?
The last value got to 46º C but then when I check it the port status, it shows level 8 with a value of 0.

I had my tech power off the unit to allow it to cool down, so we are waiting a bit before powering it back on.

Also, at what temperature does it need to get to before the "Temperature Alarm" channel is turn on?

Thanks all,
