ASUS HX97 User’s Manual 59
Setting the INT Assignment
You must use PCI INT A setting in order to properly assign the card's interrupt. On
the ASUS PCI-SC200, you assign the INT by setting jumper JP1 or JP2. The default
setting for the card already is INT A, so you do not need to change the setting to use
the ASUS PCI-SC200 with this motherboard.

Terminator Settings
SCSI devices are connected together in a “chain” by cables. Internal devices con-
nect to the ASUS PCI-SC200 with a fifty-pin flat ribbon cable. External devices
connect to the external port with a SCSI-2 cable. If there are more than one internal
or external devices, additional devices are connected with cables to form a “daisy
chain.” The SCSI chain must be “terminated” at both ends, or the devices in the
chain will not work properly.

Many SCSI devices use a set of terminating resistors to terminate the device. The
ASUS PCI-SC200 has “active” termination that you set using jumper JP5. If you
need to terminate the ASUS PCI-SC200, you do it by setting the jumper. The are two
settings, "terminated" and "not terminated," as shown below.
