19.1.1 ATX Connector Version
This power connector is available through Connector X7 (10 pins). To find the location of this connector
see
Appendix E: Connector Layout .
The EPIC/PM re5V and +5V Standby. The +3.3V for the EPIC/PM’s circuitry is generated onboard.
The onboard gen3.3V is not connected to the PC/104-Plus bus. The +3.3V pin of the ATX
connector is connected to the PC/104-Plus bus and provides power up to 6A for PC/104-Plus extension
modules.
Additionally, some peripherals such as LCD panel backlight inverters, disk drives, and PC/104 as well as
PC/104-Plus add-on cards may need more voltages (+12V, -12V, +3.3V). These voltages are not
generated onboard the EPIC/PM and need to be supplied, too, as soon as peripheral devices require
these voltages. We recommend that you use an ATX power supply with this type of EPIC/PM, even though
not all voltages are required. An adapter cable to connect a standard ATX power supply to this connector
is available from Kontron (KAB-ATX-20TO10, Part Number 96072-0000-00-0). The following table shows
the pin-out of the ATX connector.

Notes: (*) To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of IEC/EN 60950.
The current on these pins is limited to 6A/pin.
