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

SCSI terminating resistor module on the PCA is enabled.	Short	(*1)

SCSI terminating resistor module on the PCA is disabled.	Open

*1 Setting when shipped Note:

Open CNH1 5-6 pins when the SCSI terminating resistor set by CHN 2-15 pin.
