16. IDE Interface
The MOPSlcdLX features one EIDE interface (Ultra DMA66 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 in the system, you must set it as the master.
16.1 Connector
The IDE interface is available through Connector X15005 (44 pins). This interface is designed in 2mm grid
for optimal connectivity to a 2.5" hard disk.
There are several accessories available for IDE connectivity.
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 Number 96020-0000-00-0).
You can plug a Kontron chipDISK, which is an IDE hard disk that uses Flash technology, into the IDE
interface and mechanically mount it by using a mini-spacer on the chipDISK hole. You also can use a chip-
DISK adapter (chipDISK-ADA1, Part Number 96004-0000-00-0) or compact Flash adapter (CFC-ADA1, Part
Number 96004-0000-00-2) for more disk support.
The following table shows the pinout.
