Table 2: SCSI Interface Connector Pin Assignments
SCSI Interface Connector
The SCSI interface connector pin assignments are supplied for your convenience.
NOTE:
All odd pins except Pins 23, 25, 27 and 29 are connected to ground. Pin
25 is left open.
CAUTION:
Pin 25 must not be connected to ground at the HOST end or the drive end
of the cable. If the I/O connector is accidentally plugged upside down,
terminator power on Pin 26 will be shorted to ground.
The minus (-) sign next to the signals indicates asserted state is the low
voltage of the two levels used for logic signals.
Pins 23, 27, and 29 are reserved.
