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-1130U2's
SCSI ID. We recommend that you leave the ARO-1130U2 set to
SCSI ID 7, which gives the ARO-1130U2 the highest priority on
the SCSI bus.
SCSI Parity Checking—This option determines whether the
ARO-1130U2 verifies the accuracy of data transfer on the SCSI
bus. You should disable SCSI Parity Checking on the
ARO-1130U2 and all SCSI devices if any SCSI device sup-
ported by the ARO-1130U2 does not support 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-1130U2 supports Ultra SCSI data transfer speeds. If
you have any Ultra SCSI devices installed, you should enable
this setting. When this setting is enabled, the ARO-1130U2
negotiates for data transfer speeds of up to 40 MBytes/sec
(80 MBytes/sec for Wide SCSI devices).
Note:
If you use Ultra SCSI data transfer speeds, be
sure to use high-quality cables to connect the disk
drives supported by the ARO-1130U2. The quality of
the cable is much more critical when you use higher-
speed data transfer.
