This image scanner and the host are connected via an 8-bit parallel interface. The interface follows the ANSI (American National Standards Institute) SCSI 2 (Small Computer System Interface 2) Revision 10c.

This chapter provides an overview of SCSI (minimum information necessary for understanding this scanner), as well as descriptions peculiar to the scanner. For details of SCSI, refer to the ANSI standard,

The following terms are needed to understand this section.

SCSI device: A host adapter or a target controller that can he attached to the SCSI bus

Initiator: An SCSI device (usually a host system) that requests an I/O process to be performed by another SCSI device (a target).

Target: An SCSI device that performs an operation requested by an initiator

Logical Unit: A physical or virtual peripheral device that is addressable through a target

Range of support

1. System Configuration

This scanner operates under the multiinitiator, multitarget environment. An initiator function is not provided. This scanner incorporates an integrated target and logical unit (image scanner).

SCSI-ID:0 to 7, variable by DIP switch Logical unit number (LUN): 000, fixed

2.Bus phases

This scanner supports all phases except reselection phase.
