Power Supply Connectors
The conga-HPC/EVAL-Client provides the following power supply connectors:
•
standard 24-pin ATX power connector (X63)
•
additional 4-pin ATX12V power connector (X64)
•
8-21 Vmax DC banana jacks (X67, X68, X69, and X70)
Note
1. Do not supply power via the DC banana jacks and the ATX connectors at the same time.
2. In ATX mode, power must be supplied to the 24-pin ATX (X63) and the 4-pin ATX12V (X64) power connectors.
3. In ATX mode, the 3.3 V, 5 V, and 12 V are derived from the ATX power supply. If power is supplied via the DC banana jacks, the onboard
DC/DC regulators generate the 3.3 V, 5 V and 12 V. The onboard buck-boost converter generates the 12 V from 8-21 Vmax.

ATX Power Connectors
The conga-HPC/EVAL-Client provides a standard 24-pin ATX power connector (X63) and 4-pin ATX12V power connector (X64) for an ATX
power supply. Power must be supplied to both connectors. With an ATX power supply, the COM-HPC
®
module starts after you press the
power-on button SW11 (ATX mode).
To configure the power supply to operate in AT mode, set DIP SW15.1 to ON. In this mode, the module starts after the power switch on the
power supply is turned on.
