combination connector (Figure 4), located at the rear of the drive. IDE bus traffic is
supplied through a non-shielded 40-conductor I/O cable. DC power is supplied through
a separate 4-conductor power cable.

Table 4 provides the signal assignment for each pin (electronic contact) on the ATA (IDE)
bus connectors used on Zeus SSDs. Except as noted, the table applies to both the 44-
pin ATA bus connectors (Figure 3 on page 13) on used 2.5-inch drives, and the 40-pin
ATA bus/DC power combination connectors (Figure 4 above) used on 3.5-inch drives.
ATA standards require 80-conductor cables to be used for Ultra DMA
modes 3 through 5. The length of the cable shall not exceed 18 inches.
