3.5 Settings
1)Each SCSI device connected to the same SCSI bus must have a unique SCSI ID.
2)If contention occurs in the ARBITRATION phase, the priority of the SCSI use authority depends on SCSI IDs as follows:
7 > 6 > 5 > 4 > 3 > 2 > 1 > 0
(2)SCSI terminating resistor mode
Enabling or disabling the SCSI terminating resistor, module on the PCA can be set.
When the drive positions at other than the end of the SCSI bus, the SCSI terminating resistor should be disabled. Table 3.6 shows the SCSI terminating resistor mode setting.
