8 Parallel-ATA Interface (P-ATA)

The pITX-SP features one Parallel-ATA interface (up to UDMA5 mode) that can drive two harddisks. When

two devices share a single adapter they are connected in a master/slave, daisy-chain configuration. If only

one drive is connected you must set it as master.

8.1 Connector

The P-ATA interface is available through connector J3400 (44 pins). This interface is designed in 2 mm grid

for optimal connectivity to a 2.5” harddisk.

You can use two cables to directly connect a harddisk in a 2.5” form factor (KAB-IDE-2MM, part number

96021-0000-00-0) or a 3.5” form factor (KAB-IDE-25, part number 96020-0000-00-0).

Note: 1) To protect the external power lines of peripheral devices make sure that

- the wires have the right diameter to withstand the maximum available current.

- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.

2) Pin 28 is connected with 470
