SCSI II Interface
The SCSI II connection is a standard SCSI II interface and requires a shielded
high density 50-pin SCSI II bus and tag cable with an A Connector and a SCSI II
port available on the host computer. The terminator is a standard SCSI II
Terminator plug and is provided with the scanner.
The table below lists the high density 50-pin designations and associated signals
for SCSI II communications.
