Installation 11
IF INSTALLING AN 8-BIT SCSI DEVICE:
The unit ID cable contains black, brown, red/black, and orange wires. Attach three (3)
connectors from the SCSI ID select cable to the appropriate 2mm drive pins (Figure 11). The
fourth (orange) wire is not used for the 8-bit installation.
The single black wire plugs into the drive pin used to select ID1, the brown wire plugs into
the drive pin for ID2, the red/black wire plugs into the drive pin for ID4. The orange wire
is not used for this interface.
In most cases, the drive manufacturer labels each pair of SCSI ID select pins in significant bit
order (0, 1 and 2). One row of drive pins is the signal row, and one row is designated for
ground (refer to the drive manufacturer's documentation for specific pin configurations).
The Data Silo ID select cable provides 2mm, 2-conductor drive connectors. A single wire
attaches to one side of each connector (with the exception of the red/black connector). The
cable side of each connector must align with the signal pin on the drive. On the red/black
connector, the red wire aligns with the signal pin on the drive and the black wire aligns with
the ground pin.
NOTE: Some versions of the Data Silo have a reversible ID select cable. This cable may
be attached to either 2mm or 1.25mm drive pins.
