"Chassis Temperature" in Analog Input Module for FPGA (cRIO-9201)

I have just gotten my cRIO with a analog module (9201) and a digital output module (9472).

When I place an Analog Input Module on my block diagram and double click it, I can choose from the following inputs:
Channel 0 through Channel 7

AND

Chassis Temperature

I have tried to find any documentation for this "Chassis Temperature" but so far without success.

If I read this input and feed it straight to an indicator, I get values in the range of 120 to 150.. Now, without more information, this number is rather useless. Does anyone know how to transfer this data to a temperature (either in the Celcius scale or the Fahrenheit scale)?

Thank you!

I still did not find any documentation for this "feature" but I lucked out and found the following:

in the folder: \labview 7.1\examples\FPGA\CompactRIO\cRIO-910x\

you should have a file called:
cRIO-910x support files.llb

in this there is a convert to temperature vi.

To get the raw data as a temperature, it looks like all you have to do is divide the binary data by 4 and the answer will be in Celcius.
