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.
