Adaptec SCSI Card 19160 User's Reference The following example shows two Fast/Ultra Narrow SCSI devices connected to the external connector. As in the previous diagrams, the last device on the SCSI bus must use an SE terminator plug. Terminated T device Maximum Cable Lengths The total length of cabling (internal and external) on the SCSI bus cannot exceed the maximum lengths listed in the following table. Maximum Cable Length Data Transfer Rate Maximum Devices Supported 25 m (82 ft) Ultra160 SCSI (160 MBytes/sec) 1 Ultra2 SCSI (80 MByte/sec) 12 m (39.4 ft) Ultra160 SCSI (160 MBytes/sec)1 15 Ultra2 SCSI (80 MByte/sec) 3 m (9.8 ft) Fast SCSI (10 MBytes/sec) 7 3 m (9.8 ft) Ultra SCSI 4 (40 MBytes/sec for 16-bit, 20 MBytes/sec for 8-bit) 1.5 m (4.9 ft) Ultra SCSI 5-82 (40 MBytes/sec for 16-bit, 20 MBytes/sec for 8-bit) 1 Mixing Fast/Ultra devices with Ultra2 SCSI or Ultra160 SCSI devices on the LVD Ultra160 segment causes the entire SCSI bus to default to Ultra SCSI speeds and cable requirements. 2 Ultra SCSI data transfer rates do not currently support more than eight devices.
