1.3 Software Compatibility
Pluto
’s operating system compatibility is a function of both the Pluto baseboard and the specific ETX CPU module
attached to it. The baseboard and has been qualified for use with Windows XP/XPe and Linux 2.6. The OSes
supported by the ETX CPU module vary according to the specific ETX module used. Consult the appropriate ETX
CPU module’s user manual for details on its OS support.
1.4 Thermal Considerations and Heatspreader
Pluto models based on the Intel E3845 CPU specified for an operating temperature range of -40
o
C to +85
o
C.
Models with the AMD G-Series CPUs are specified for an operating temperature range of -20
o
C to +71
o
C.
Diamond Systems provides a heatspreader attached to Pluto as a conductive cooled thermal layer. However, this
heatspreader by itself does not constitute the complete thermal solution necessary for any specific
implementation, but provid
es a common interface between the single board computer and the customer’s
implementation-specific thermal solution.
The outside surface of the Pluto heatspreader must be kept at a temperature not to 71
o
C. If your
environment causes the temperature on the outside surface of the heatspreader to exceed the appropriate
temperature, you are responsible for removing the additional heat from the system through either an additional
passive thermal solution or fan solution.
Pluto’s integrated heatspreader makes thermal contact with the heat generating components and provides a flat
surface on the bottom of the assembly for mating to the system enclosure. This technique facilitates efficient
removal of heat from the COM module without the need for a fan. Four mounting holes on the bottom of the
conduction cooled heatspreader are provided to mount Pluto in an enclosure or to a bulkhead. These mounting
holes are #6-32 threaded holes on 2.8" centers.
