SCSI Terminators
The 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 SCSI
devices should have the terminating resistors removed. The fol-
lowing figure shows two examples of SCSI device connections to
the AHA-1740A/1742A/1744 Host Adapter.
The AHA-1740A/1742A/1744 is a SCSI device, and has socketed
on-board terminators that should be removed if both the internal
and 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-1744
remove the RN2, RN4 and RN5 terminators.
