Rear Panel Connectors 5

This section describes how to use the rear panel connectors that are

common to all models of the tape drive.

For the locations of these connectors, see the following illustrations:

Power Connector Pin

Assignments

Pin assignments for the 4-pin power connector are listed here. Pin 1 is

indicated by a solid red dot in the illustrations.

Loader/Library Interface

Connector

The connector for the library/tape drive interface is an RS-422 serial port

set to 9600 baud, 8 bits per character, no parity, and 1 stop bit. All data

sent to or from the library/tape drive interface consists of bit-wise

encoded hex values.

This 10-pin loader connector provides the signals used when the tape

drive is part of a loader/library configuration. The loader connector

provides a “universal port” that can support various serial interface

protocols. The electrical signals from the DLT-S4 tape drive need to be

translated to the appropriate serial interface protocol by a hardware and

software interface system.

The Loader/Library Controller interface conforms to the T10 Committee

Automation/Drive – Transport Protocol (ADT) Specification (see

www.t10.org).
