TERMINATION

To keep signals on the SCSI bus from being reflected, “terminators” must be placed at each end of the physical bus.

These terminators may be either active or passive. Passive termination is a resistor network. Active termination uses a

voltage regulator (the active component) to regulate the power of the resistor network to provide more stable termina-

tion. Active termination is always preferred over passive termination.

Depending on your SCSI device, termination is supplied by a using a physical connector, by flipping a dip switch, or by

selecting the termination setting in software.

Termination is always at both physical ends of the bus. (Note that all HP jukeboxes use active termination.)
