SCSI Centronics50 male forced perfect terminator (FPT). FPT terminator is recommended over the passive and active types for high-speed devices and long distance applications. It goes beyond stabilizing the power applied to the terminator by altering its impedance to actively compensate for variations among many different cables and devices by means of diode switching and biasing. It has built-in troubleshooting LEDs. (Connectors: Cen50 Male)
