Digital I/O
The 8-bit Digital I/O (DIO) connector allows for input/output signals of digital logical states de-
fined by voltage levels.
Jumper Setting
DIO signal and power can be configured via jumper settings as previously instructed in this
chapter.

„ ATX 8-pin Power
Connector
Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1. An
ATX12V power supply unit has a standard 24-pin ATX main power connector that must be in-
serted into the 24-pin connector. The 8-pin +12V power connector enables the delivery of more
+12VDC current to the processor's Voltage Regulator Module (VRM).
The power connectors from the power supply unit are designed to fit the 24-pin and 8-pin con-
nectors in only one orientation. Make sure to find the proper orientation before plugging the
connectors.
The system board requires a minimum of 300 Watt power supply to operate. Your system con-
figuration (CPU power, amount of memory, add-in cards, peripherals, etc.) may exceed the mini-
mum power requirement. To ensure that adequate power is provided, we strongly recommend
that the system is supplied with a minimum of 400 Watt power.
Important:
Insufficient power supplied to the system may result in instability or malfunction
of the add-in boards and peripherals. Calculating the system's approximate power
usage is important to ensure that the power supply meets the system's consump-
tion requirements.
