Ruggedized Terminals

Overview

Information is highly critical to manufacturing operations. It must be read, it must be current, and it must be readily available – regardless of local conditions.

Digital's RT family of ruggedized terminals – the RT100, RT102, RT103, and RT137 – are specifically designed for use in harsh, industrial environments. But what is a harsh, industrial environment and how can ruggedized terminals withstand the conditions there?

Digital's RT terminals work with any UNIBUS or LSI-11 PDP-11, VAX, or DECsystem-10 and -20 processor and are supported by all Digital operating systems.

RT100 Ruggedized Terminal

The RT100 ruggedized video terminal combines full VT100 functionality with packaging to withstand the abuse of hostile industrial environments where full data collection capability is needed. Its industrial packaging includes:

The RT100 possesses full universal VT100 performance characteristics and compatibility. Like the VT100, an RT100's performance can be enhanced with the advanced video option, which adds such video attributes as blinking, underlining, bolding, and reverse video. For more details on the RT100's capabilities, read the description of the VT100 terminal.

The following RT100 models are available:

RT100-AA
Industrial VT100, 120 Vac, 50/60 Hz, RS232 interface.
RT100-AB
Industrial VT100, 240 Vac, 50/60 Hz, RS232 interface.
RT100-BA
Industrial VT100, 120 Vac, 50/60 Hz, 20 mA interface.
RT100-BB
Industrial VT100, 240 Vac, 50/60 Hz, 20 mA interface.

RT102 Ruggedized Terminal

The RT102 terminal, a ruggedized version of Digital's VT102 video terminal, contains all the universal performance characteristics of the VT100 terminal, the ruggedized features of the RT100 terminal, and the built-in advanced video option and printer port of the VT102.

For formatting, prompting, guidance, and alarm functions, the RT102's advanced video feature permits any character to be displayed in a user-selectable combination of blinking, underlining, boldface, and reverse video. The advanced video option also increases screen capacity by greater than 70 percent. The RT102 includes the built-in printer port connector. Immediate printout of data on the video display is possible by either operator or host command for use when additional analyses or status documentation is required.

The following RT102 models are available:

RT102-AA
Industrial VT102, 120 Vac, 50/60 Hz, RS232 interface.
RT102-AB
Industrial VT102, 240 Vac, 50/60 Hz, RS232 interface.
RT102-BA
Industrial VT102, 120 Vac, 50/60 Hz, 20 mA interface.
RT102-BB
Industrial VT102, 240 Vac, 50/60 Hz, 20 mA interface.

RT137 Terminal with Bar Code Capability

The RT137 monitor and keyboard are housed in metal enclosures, like the other members of Digital's industrial terminal family, and provide bar code handling capability.

Designed for data-collection applications that require or can benefit from machine-readable input, the RT137 combines the flexibility of bar code with RT100 terminal features.

A bar code reader module that is an integral component of the RT137 architecture, a bar code wand, and adaptable bar code keyboard provide versatility for data collection applications. The RT137's construction not only means it can operate reliably in harsh industrial environments, but also allows the terminal to be located right where you need it.

The bar code legend can be used to represent almost any form of data, allowing the encodement of part numbers, quantities, transaction types, warehouse locations, and badge numbers, to name a few.

The RT137 contains all the ruggedized features of the RT100 terminal, but also includes a bar code wand. This wand is a ruggedly constructed visible-light pen that is virtually immune to mechanical shock and vibration.

As with other ruggedized Digital terminals, the RT137 has all the universal performance characteristics of our VT100 terminal, plus the following features.

The following RT137 models are available:

RT137-AA
RT137-AE and VT100 keyboard, 120 Vac, EIA interface.
RT137-AE
