・ Maximum Sync Transfer Rate
Using this option enables you to set the maximum synchronous transfer rate
that this card supports. The default setting is ｢40.0 MB/s｣.
This card supports a sync transfer rate up to 40.0 MB/s that is the maximum
value of the "Ultra Wide SCSI". When the SCSI device in use is an ultra wide
SCSI one, the sync transfer rate can set to the maximum rate of 40.0 MB/s
(when the "Support for Ultra SCSI Speed" is set to ｢Enabled｣ and the "Initiate
Wide Negotiation" is set to ｢yes｣). When the SCSI device in use is a fast wide
SCSI one, the maximum rate is limited to 20.0 MB/s.
If this card is not set to negotiate sync data transfer (that is, if Initiate Sync
Negotiation is set to ｢no｣), the maximum synchronous transfer rate is the
maximum rate at which this card accepts data from a SCSI device during
negotiation.
・ Enable Disconnection
This option allows you to specify whether to enable the SCSI device so that it
can be disconnected from the SCSI bus by using this card. If disconnection is
enabled, this card can perform another operation using the SCSI bus while the
SCSI device is temporarily disconnected. The default setting is ｢yes｣. (If this
option is set to ｢no｣, the external SCSI device cannot be disconnected from
the SCSI bus.)
When two or more SCSI devices are connected to this card, you should leave
the Enable Disconnection set to ｢yes｣. This optimizes the performance of the
SCSI bus.
・ Initiate Wide Negotiation
This option allows you to determine whether to use data transfer (Wide
Negotiation) at a data width of 16 bits instead of 8 bits. The default setting is
｢yes｣.
