RT01 DEC-link Data Entry Terminal

This document describes the Digital Equipment Corporation's RTOI DEC-link Data Entry Terminal, an economical, self-contained, and remotely locatable device for data entry. It offers Teletype and EIA serial line compatibility, featuring an integral 16-character keyboard for data input and "Nixie" tubes to display up to 12 digits of numeric data, along with four programmable status indicators.

Key attributes of the DEC-link include its versatility, with character significance defined by software; portability due to its compact, typewriter-like size; and high reliability, attributed to its all solid-state design and a keyboard rated for 20 million operations, eliminating the need for routine maintenance. It boasts low cabling costs, connecting via standard 4-wire twisted pair cable or, with a modem, over voice-grade telephone lines, and is hardware compatible with DEC's full line of data communications equipment.

The terminal is suitable for a wide range of applications, such as Stockroom Inventory Control, Data Logging, Information Retrieval, Production Line and Quality Control Monitoring, Security Systems, and Management Information Systems. It effectively fills the performance and price gap between full-scale video displays and electro-mechanical, hard-copy devices. Specifications detail its power requirements (115/230 VAC, 30W), physical dimensions (15"Wx12"Dx6"H, 12 lbs), display options, control functions, and data input/output parameters, including 20MA TTY Isolated Current Loop or EIA RS232C levels, 110/300 Baud rates, and an 8-level asynchronous serial ASCII character format.
