Host Adapter and the SCSI Bus
is a bus mastering host adapter which works with the host computer to
provide control for the SCSI bus. By daisy chaining peripheral devices together, up to
seven devices can be linked with
. The host adapter can be placed in any
standard PCI slot on the bus.
SCSI bus preparation
Each peripheral device attached to the SCSI bus can either be an internal or external
device. Each peripheral has a specific device ID, commonly referred to as a SCSI ID.
Please refer to your peripheral documentation to determine switch or jumper settings
for SCSI IDs. No two devices can have the same ID; the device ID uniquely defines the
device to the SCSI bus.
SCSI bus termination
The SCSI bus structure has a length limitation as well as a requirement for termination
at each end of the SCSI cable. The cable is designed to connect in a daisy chain
fashion. No branching is permitted in the SCSI bus. The first and last physical SCSI
device on the SCSI bus must be terminated (
