•We recommend using active SCSI terminators on fast single-ended SCSI busses. The active terminator helps maintain a high degree of signal integrity and improves noise immunity.

•A minus sign (-) next to the signal indicates an active low signal.

•All passive terminators use a 220Ω pull-up resistor and 330Ω pull-down resistor for each signal. Resistor tolerances in the terminator network are ±5%, or less. Use resistors with ±1% tolerance for improved noise margins.
