SCSI Select Settings

SCSI Bus Interface Definitions

The following settings are the SCSISelect settings most likely to
require any modification.
Host Adapter SCSI ID— This option sets the ARO-1130CA's
SCSI ID. The default setting is SCSI ID 7, which gives the
ARO-1130CA the highest priority on the SCSI bus. We recom-
mend that you leave the ARO-1130CA set to SCSI ID 7.
SCSI Parity Checking—This option determines whether the
ARO-1130CA verifies the accuracy of data transfer on the SCSI
bus. The default setting is Enabled. You should disable SCSI
Parity Checking on the ARO-1130CA and all SCSI devices if
any SCSI device supported by the ARO-1130CA does not sup-
port SCSI parity; otherwise, leave it enabled. Most SCSI
devices do support SCSI parity. If you are not sure whether a
device supports SCSI parity, consult the documentation for the
device.
Host Adapter SCSI Termination—This option is used in con-
junction with your motherboard termination settings. Refer to
your motherboard documentation for instructions on properly
setting termination.
Host Adapter UltraSCSI—This option determines whether the
ARO-1130CA supports UltraSCSI data transfer speeds. The
default setting is Disabled. If you have any UltraSCSI devices
installed, you should enable this setting. When this setting is
enabled, the ARO-1130CA negotiates for data transfer speeds
of up to 20 MBytes/sec (40 MBytes/sec for Wide SCSI devices).
Note:
If you use UltraSCSI data transfer speeds, be
sure to use high-quality cables to connect the disk
drives supported by the ARO-1130CA. The quality of
the cable is much more critical when you use higher-
speed data transfer.
