A.2.2 The SCSI Interface
The SCSI interface conforms to ANSI X 3T10.11/1142. The SCSI
interface operates as 16-bit, synchronous or asynchronous, SE or LVD,
and supports Ultra160 SCSI protocols. Arbitration is supported for 8-bit
(at lower SCSI speeds) and 16-bit. Active SE or LVD SCSI termination
is provided automatically. SCSI termination power is supplied by the
board.
Connector J3 is a 68-pin HD right angle connector that protrudes through
the back panel bracket and is used for external connections. Connector
J4 is a 68-pin HD right angle header used for internal connections.
Table A.4 and Table A.5 show the signal assignments for J4 and J3
respectively.
