Installing and Using The VT320 Video Terminal

This document is a comprehensive user manual for the VT320 video terminal, published in June 1987. It provides detailed instructions for installing, operating, and maintaining the international version of the terminal, primarily for Western European countries.

The manual is structured into seven chapters and five appendices, covering:

• Installation: Step-by-step guidance on unpacking, connecting the keyboard, power cord, and system/printer cables, adjusting the display, and initial configuration such as selecting keyboard language and baud rate (default 9600 baud).
• Terminal Overview: A description of the VT320's components (14-inch monochrome screen, keyboard), its function for interacting with host computer applications, and its ability to emulate VT200, VT100, or VT52 series terminals.
• Keyboard Functions: Detailed explanations of the main, editing, numeric, and top-row function keys, along with descriptions of indicator lights and audible alerts (keyclick, margin bell, warning bell).
• Set-Up Procedures: Instructions on how to access and navigate the terminal's seven set-up screens (Set-Up Directory, Display, General, Communications, Printer, Keyboard, Tab) to customize various operating features and save settings to nonvolatile memory.
• Character Sets and Composition: Information on the supported 8-bit multinational (DEC Multinational, ISO Latin-1) and 7-bit National Replacement Character (NRC) sets. It guides users on composing special characters not found directly on the keyboard through two- or three-stroke sequences.
• Peripherals and Communication: How to connect and utilize printers (with modes like Normal, Auto Print, Printer Controller, Local Controller) and modems, detailing communication standards (RS232-C, DEC-423) and flow control (XON/XOFF).
• Troubleshooting and Service: Solutions for common operational issues, information about the power-up self-test and error messages, and options for obtaining service from Digital Equipment Corporation.
• Appendices: These sections provide technical specifications, ordering details for optional accessories and related documentation, comprehensive communication protocols (cables, pin assignments), various keyboard models, and a summary of VT320 control functions for programmers.

The manual is designed to be a complete resource for both end-users and programmers dealing with the VT320 terminal.
