Getting Started

HostAdapter and the SCSI Bus

 

INI-9090Uis 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 INI-9090U. The

host adapter can be placed in any

2 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 ID’s. 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 (FIGURE 2).
