3. IDE connectors (40-1 pin PRI_IDE, SEC_IDE)
These connectors support the provided Ultra ATA/133 IDE hard disk ribbon
cable. Connect the cableʼs blue connector to the primary (recommended) or
secondary IDE connector, then connect the gray connector to the Ultra ATA/133
slave device (hard disk drive) and the black connector to the Ultra ATA/133
master device. Connecting non-Ultra ATA/133 devices to the secondary IDE
connector is recommended.
4. Digital audio connector (3- pin SPDIF)
This connector is for the S/PDIF audio module that allows digital sound input.
• Pin 20 on each IDE connector is removed to match the covered hole on
the Ultra ATA cable connector. This prevents incorrect orientation when you
connect the cables.
• For Ultra ATA/133 IDE devices, use an 80-conductor IDE cable.
• The hole near the blue connector on the Ultra ATA/133 cable is intentional.
• Use 75 ohm impedance matched coaxial cables for your S/PDIF connection.
• The S/PDIF module is purchased separately.
