4.3.3 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 4.7 shows the SCSI terminating resistor mode setting.

Table 4.7 SCSI terminating resistor mode (CNH1)

SCSI terminating resistor mode	CNH 1	05-06
