ATA Cables Compared
There are three types of ATA cables available.
Depending on the type of drive being connected, it
is important to use the right cable.
• Ultra ATA66 Cable – The Ultra ATA66 cable
(Figure 1) packaged with the Tempo Ultra
ATA66 connects the Tempo to your IDE hard drive.
It features an 80-conductor cable with three 40-pin
connectors and allows the connection of up to two
drives. This cable is required to take advantage of
Ultra ATA/66 technology; however, it is fully
backward-compatible with Ultra ATA/33 drives.
• Standard ATA Cable – Uses a 40-pin,
40-conductor cable to connect IDE drives to the
40-pin IDE connectors of PCI-based computers.
A standard ATA cable supports ATA/33 but does not
support Ultra ATA/66 technology.
• CS (Cable Select) ATA Cable – Not commonly
used, the CS ATA cable is required when each drive
on the cable has an identical CS jumper setting.
A CS ATA cable is not supported with the Tempo
Ultra ATA66.
Support Note:
adding three or four drives to your
computer, you will require an additional Ultra
ATA66 cable, which is sold separately. DO NOT
use a standard ATA cable or a CS ATA cable.
