Cabling and connectors
The drive provides standard, single-ended SCSI transmission. ANSI SCSI
standards specify the technical requirements for correctly cabling and connecting
single-ended devices.
Either 50-pin flat cable or 25-signal twisted-pair cable with a maximum length of 6
meters (19 feet) may be used to connect the drive to its SCSI host adapter output. If
twisted-pair cabling is used, connect the twisted pairs to physically opposing
contacts on the connector. A stub length no greater than 0.1 meter should be used
off the mainline connection within any connected equipment.
