56 ASUS P/I-P55SP4V User’s Manual
Decide whether or not you need to terminate the PCI-SC200 based on its position in
the SCSI chain. Only the devices at each end of the chain need to be terminated. If
you have only internal or only external devices connected to the PCI-SC200, then
you must terminate the PCI-SC200. If you have both internal and external devices
connected, you must not terminate the card. See the following example which
illustrates this concept.

SCSI ID Numbers
All SCSI devices, including the PCI-SC200 interface card must have a SCSI identi-
fication number that is not in use by any other SCSI device. There are eight possible
ID numbers, 0 through 7. The PCI-SC200 has a fixed SCSI ID of 7.
You can connect up to seven SCSI devices to the interface card. You must set a SCSI
ID number for each device. SCSI devices vary in how they set the ID number. Some
use jumpers, others have some kind of selector switch. Refer to the manual for any
device you install for details on how to set its ID number.
