(5) Setting the bus width of the SCSI interface
By establishing a short-circuit between the 13 and 14 CN2 setting terminals, the bus width for the
SCSI interface is forcibly set to the 8-bit bus mode. This setup terminal must be set in order to
guarantee the physical level of the SCSI interface's upper bus (DB8-15, P1) inside the IDD only
when the top-level bus (DB8-15, P1) for the IDD SCSI interface is not connected to the external
part of the IDD.

In addition to the previously described settings using setting terminals, the IDD is provided with several
mode settings. The mode settings are enabled by specifying the CHANGE DEFINITION command.
Table 5.7 lists the mode settings and their settings at factory shipment.
