CAUTION:
To prevent severe and possibly irreparable damage to the system, it is critical
that the power connector is wired correctly. Make use of all +5 VDC pins and all
ground pins to prevent excess voltage drop.
Note:
The +3.3 VDC, +12 VDC and -12 VDC inputs on the power connector are only required for
PC/104-
Plus
and PC/104 expansion modules that require these voltages.
Table 3 lists the pinout for the main power connector.
