Connector DD-68P SCSI-2 68 pin (Wide SCSI) (differential)

The differential bus allows the transport of the signals on a pair of wire. Information is coded by difference between the two wire (each one conveying the opposite tension) in order to compensate for the electromagnetic disturbances, which allows an important distance from wiring (about 25 metres). One generally distinguishes mode LVD (differential low tension), based on signals 3.3V, and mode HVD (differential high voltage), using signals 5V

Length of bus SCSI
The standard envisages a maximum length according to the type of bus and the number of peripherals. The lengths indicated are possible with good cables and active terminations.

With a minimum spacing of 30 cm between two peripherals, one would need at least four metres fifty to carry out a chain SCSI of 16 units, that is to say three times the maximum length of possible wiring. It is possible to exceed this limit thanks to very top-of-the-range cables (Teflon + Argent + Or with low impedance (90 Ohms)) and by using two active terminations.
