Typically the narrow scan cable has 50 pins.
68
68 pins.
The beauty of SCSI is that supports many physical interfaces. Fibre channel SCSI uses 4 "pins" which can be copper, or fibre optic cabling. Parallel scsi which you are probably asking about can use 25, 50 or 68 pins. So you should rephrase your question to specify the interface you are asking about ... but I guess that would liook kinda dumb, ... "How many pins does a 50-pin SCSI interface have" :)
yes
SCSI, Fast SCSI, Ultra SCSI, Ultra2 SCSI: 8 devices Wide SCSI, Fast Wide SCSI, Ultra Wide SCSI, Wide Ultra2 SCSI, Ultra3 SCSI, Ultra160 and 160+ and Ultra320 : 16 devices Of course, the number of devices supported depends not only on protocol limitations, but cable length, number of cables used, etc.
Ultra wide SCSI. wide SCSI buses support 16 devices, rather than the eight devices specified in regular SCSI.
Depends on what the SCSI is. Ultra? Ultra Wide? Ultra Wide 2? many different types.
Wide SCSI bus can support up to 16 devices using channels 0-15.
The maximum length of cable that can be used for SCSI-3 is 12 meters. This is applicable to Ultra2 Wide, Ultra 160, and Ultra 320.
16 devices can be connected
The wide SCSI-2 uses a wider data path & emdash;16 bit rather than the normal 8 bit & emdash; for the same 10 Mbps. Combining both fast and wide can, in theory, reach 20 Mbps.
8 or 16 depending upon the SCSI hardware being used. In a narrow bus, you can use a SCSI ID of 0-7, and in a wide bus, you can use 0-15.
