Power button (input)

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

Note. The VSB (Volt Stand-By) voltage is useful for Power management applications only.

Note. The +12VDC and -5VDC voltages are neither used nor generated by the CPU-1461 module: they are only conveyed on the PC/104-Plus 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 TO THE MODULE.
