JP 5 JP 5 ASUS SCSI Cards Jumpers Settings R PCI SCSI Cards Terminator Settings for the ASUS PCI-SC200 The ASUS PCI-SC200, on the other hand, has "passive" termination that you must set using jumper JP5. There are two settings, "terminated" and "not terminated," as shown below. Terminated (Default) Not Terminated Terminator Setting (Terminated / Not Terminated) Decide whether or not you need to terminate the ASUS 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 ASUS PCI-SC200, then you must terminate the ASUS PCI-SC200. If you have both internal and external devices connected, you must not terminate the card. See the following two examples which illustrate this concept. OR Termination Required (JP5 Open) SCSI Device 1 SCSI Device 2 (End Device) Termination Required Only Internal or Only External Devices No Termination Required (JP5 Short) SCSI Device 3 SCSI Device 4 (End Device) Termination Required Both Internal and External Devices SCSI Device 2 Termination Required SCSI Device 1 (End Device) ASUS SC200/SC860 Reference Guide 3
