index | next in thread | raw e-mail
i have a nakamichi MBR-7 scsi-ii 2x cdrom 7 changer. the unit has
internal terminators controlled by a rear panel dip switch. the
rear panel has 2 centronics 50-pin scsi connectors. the scsi card
is an ASUS SC-200.
regardless of whether the internal scsi terminator are enabled or
i use an external scsi terminator (active) on the lower scsi
connector of the MBR-7, i get scsi phase errors. when the cable
connects the SC-200 to the upper scsi connector on the MBR-7, the
unit reponds normally.
