11 EIDE Interface (P-ATA)
The JRexplus-DC features one EIDE interface (up to UDMA5 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.
Note: The connector of the JRexplus-DC was intended for the use with a cable link. When a KONTRON chip-
disk or a CF card adapter is used the PCB's of these components point away from the board.
11.1 Connector
The EIDE interface is available through connector J13 (44 pins). It is designed in 2 mm grid for connectivity
to a 2.5” hard disk. You can use two cables to directly connect a 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 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.
