SCSI TerminatorsThe SCSI bus must be terminated correctly to ensure proper op-eration. Only the first and last device on the SCSI bus (cable)should have the terminating resistors installed. All other SCSIdevices should have the terminating resistors removed. The fol-lowing figure shows two examples of SCSI device connections tothe AHA-1740A/1742A/1744 Host Adapter.The AHA-1740A/1742A/1744 is a SCSI device, and has socketedon-board terminators that should be removed if both the internaland external host adapter connectors are used. These can be rein-stalled at a later time, if desired. On the AHA-1740A/1742A re-move the RN5, RN6 and RN7 terminators. On the AHA-1744remove the RN2, RN4 and RN5 terminators.Figure 2-1.
