Copyright © 2002 by LSI Logic Corporation. All rights reserved.

The following applies to the high-density SCSI connector described in

Table A.3

:

A hyphen before a signal name indicates that signal is active low.

The connector pin refers to the conductor position when using 0.025
inch centerline flat ribbon cable with a high-density connector
(AMPLIMITE.050 Series connectors).

Eight-bit devices connected to the P-Cable must leave the following
signals open: -DB (8), -DB (9), -DB (10), -DB (11), -DB(12), -DB (13),
-DB (14), -DB 15), and -DB (P1).

All other signals should be connected as defined.

Caution:

Lines labeled RESERVED should be connected to Ground
in the bus terminator assemblies or in the end devices on
the SCSI cable. RESERVED lines should be open in the
other SCSI devices, but can be connected to Ground.
