VI. PCI-SC200 (SCSI ID Numbers) VI. PCI-SC200 SCSI Card 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. See the following example which illustrates this concept. Termination Required (JP5 Open) SCSI Device 1 SCSI Device 2 Termination Required (End Device) No Termination Required (JP5 Short) SCSI Device 3 SCSI Device 4 Termination Required (End Device) SCSI Device 2 Termination Required (End Device) SCSI Device 1 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 PCI-SC200 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. 58 P/I-P55TP4N User's Manual
