(5) Setting the bus width of the SCSI interface (CN2)
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.

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.
