Can someone explain to me the difference between ormal scsi and differential scsi?
ANSWER From: ralf@alum.WPI.EDU (Ralph Valentino) “Normal” SCSI is also called “Single-ended” SCSI. For each signal that needs to be sent across the bus, there exists a wire to carry it. With differential SCSI, for each signal that needs to be sent across the bus, there exists a pair of wires to carry it. The first in this pair carries the same type of signal the single-ended SCSI carries. The second in this pair, however, carries its logical inversion. The receiver takes the difference of the pair (thus the name differential), which makes it less susceptible to noise and allows for greater cable length.
