ASUS PCI-SIU2 User’s Manual
PCI-SIU2’s SCSI termination can be set to auto-termination or programmable
mode via the SmartSCSI Setup Utility. This feature allows the operator to
switch the auto-termination On or Off. If auto-termination is switched Off, the
operator can manually program termination for the host adapter. There are
several ways to manually control terminating the host adapter on the SCSI bus.

NOTE: When mixing 68-pin and 50-pin SCSI devices on the same daisy
chain, it is highly recommended that the 68-pin SCSI device is con-
nected furthest away from the PCI-SIU2 host adapter.
