IDE / PATA Interface (J5)
The IDE interface is available to connect up to two IDE devices, such as hard disks, CD-ROM
drives, or Disk on Module devices. Connector J5 is the IDE controller with a 44-pin 2 mm
connector. Use CMOS Setup to specify the drive parameters of the drive. If you attach only one
IDE, it must be configured (jumpered) as the master device; a single IDE device configured as a
slave device can cause system failures.
Cable length must be 18" or less to maintain proper signal integrity.
This interface supplies power to 2.5" IDE drives. If you are connecting a 3.5" drive to the
interface (using the VL-CBR-4405 44-pin to 40-pin IDE adapter), you must supply external
power to the drive. The power cable attached to a 3.5" drive must be properly grounded so that
motor current is not returned via the grounds in the data cable.
VersaLogic offers a number of Disk on Module (DOM) flash storage devices, in capacities from
1 to 8 GB, that attach to the IDE connector. The VL-F20 series of DOMs have a 44-pin 2 mm
connector and are secured to the board with one M2.5 x 6mm nylon pan head Philips screw.
Screws are available in 10-count packages as part number VL-HDW-108.
