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.

Terminator Setting (Terminated / Not Terminated)

Terminated (Default) Not Terminated
