2.5.2 ST52160WC interface connector
The ST52160WC uses an 80-pin blindmate single-connector attachment
(SCA-2). It is a single-piece connector that provides power to the drive
through the SCSI bus. The remote LED, motor start options and addi-
tional binary codes are also placed on the SCSI bus. Pin 1 on the
connector is shown in Figure 3 on page 19.
We recommend the AMP blindmate receptacle assembly (part number
787311-1).
