VI. ASUS PCI SCSI Cards

Setting Up the ASUS PCI-SC200 & PCI-SC860

There are two jumper settings you may need to make on the ASUS PCI-SC200 to set it up. One setting assigns the PCI INT interrupt, the other sets the card’s termination. The ASUS PCI-SC860 has no jumper settings but you should read the “Terminator Requirements.”

Setting the INT Assignment for the ASUS PCI-SC200

You must use PCI INT A setting in order to properly assign the ASUS PCI-SC200'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 Requirements for SCSI Devices

SCSI devices are connected together in a “chain” by cables. Internal devices connect to the ASUS PCI-SC200 or ASUS PCI-SC860 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.” Terminating the devices on the ends of the SCSI Bus “chain” is necessary for SCSI devices to work properly. Termination of the devices between the ends must be Disabled.
