ATX Power Supply

¾Connect pin 1 and pin 7 to the ground signal of the ATX Power Supply Unit.

¾Connect pin 2 and pin 8 to the +5VDC source on the ATX Power Supply Unit.

¾Connect pin 4 to the +12VDC and pin 6 to the –12VDC sources on the ATX Power Supply Unit only if requested by other boards connected to the PC/104 ISA bus (see the following note).

¾Connect pin 11 to the +5VSB source on the ATX Power Supply Unit. This signal is always high, even if the power supply is turned off.

¾Connect pin 12 to the ATX ON signal of the ATX Power Supply Unit. This signal is used to power on the Power Supply itself.

Power button

If the soft power management is enabled, a low signal in this pin turns the system on or off.

Note. The +12VDC and -12VDC voltages are neither used nor generated by the SpacePC 1232 module: they are only conveyed on the PC/104 bus (connector J1) and can be used by other devices or modules that are stacked onto the CPU module.

WARNING! IMPROPER CONNECTION OF THE POWER SUPPLY WILL RESULT IN SERIOUS DAMAGE FOR THE MODULE.
