13 Parallel-ATA Interface (P-ATA)
The JRexplus LX features one Parallel-ATA interface (Primary channel, UDMA33/66 mode) that can drive
two hard disks. 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. Alternatively the same interface can
be used for Compact Flash card applications. Due to mechanical restrictions KONTRON chipdisks can't be di-
rectly mounted. A stand-off extension for the pingrid is needed to connect the chipdisk properly.
13.1 Connector
The P-ATA interface is available through connector X6 (44 pins). This interface is designed in 2 mm grid for
optimal connectivity to a 2.5” hard disk. You can use two cables to directly connect a hard disk 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 num-
ber 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 Ω to Ground for Cable Select P-ATA devices.
