IV. PCI-SC200 SCSI Card

Setting the INT Assignment

You must use PCI INT A setting in order to properly assign the card's interrupt. On

the 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

PCI-SC200 with this motherboard.

SCSI devices are connected together in a "chain" by cables. Internal devices con-

nect to the 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

PCI-SC200 has "active" termination that you set using jumper JP5. If you need to

terminate the PCI-SC200, you do it by setting the jumper. The are two settings,

"terminated" and "not terminated," as shown below.
