4 Technical Summary 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 unterminated, as shown below. JP5: Terminator setting Lel Termination OEnabled (default) In 0_ Termination Disabled 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. The figures on the next page illustrate these requirements. SCSI ID Numbers All SCSI devices, including the PCI-SC200 interface card must have a SCSI identification number that is not in use by any other SCSI device. There are eight possible ID numbers, 0 through 7. The PCISC200 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. 4-17
