Set the TERM switch on the SCSI board to match your configuration, as follows.

Set the SCSI terminator switch of the SCSI interface board to OFF. (When shipped from
the factory this is ON.)
* In this case you must also set the SCSI terminator of the internal disk itself to ON.
( 324) And if you are connecting one or more external SCSI devices, you must also
be sure to switch ON the terminator of the final device in the chain. (Alternatively,
turn its terminator switch ON.) ( 328)
If you are not connecting an internal hard disk
Set the SCSI terminator switch of the SCSI interface board to ON. (When shipped from
the factory this is ON.)
* If you are connecting one or more external SCSI devices, you must also be sure to
switch ON the terminator of the final device in the chain. (Alternatively, turn its
terminator switch ON.) ( 328)
