    Barracuda 36ES Product Manual, Rev. H Notes [ ] for tables 14 through 18. See Section 9.6.4.2 for detailed electrical characteristics of these signals. The conductor number refers to the conductor position when using 0.025-inch (0.635 mm) centerline flat ribbon cable. Other cables types may be used to implement equivalent contact assignments. Connector contacts are on 0.050 inch (1.27 mm) centers.

    Barracuda 36ES Product Manual, Rev. H 9.7.1.1 Single-ended drivers/receivers for N and W models For “N” and “W” models which use single-ended drivers and receivers, typical circuits are shown in Figure 31. Terminator circuits (see Note [1]) are to be enabled only when the disc drive is first or last in the daisy-chain. Transmitter characteristics Single-ended drives use an ANSI SCSI compatible open collector single-ended driver.

  • Page 92: Terminator Requirements

    Barracuda 36ES Product Manual, Rev. H Terminator requirements N and W models have active, permanently mounted LSI terminator circuits on board the PCB. All single initiator/single target (non-daisy-chain) applications require that the Initiator and disc drive be termi- nated. Daisy-chain applications require that only the units at each end of the daisy-chain be terminated. All other peripherals on the chain must not be terminated (see Figure 27).
