The VT520 is like having four terminals in one. You can support four
independent sessions over a single wire with SSU (Session Support Utility)
or you can access applications via the three connectors provided on the
terminal. For example, with the VT520, a telemarketing sales representative
talking on the telephone can easily flip from a stock status application to
a customer profile report to an order-entry system to a credit and
collection report.
The VT520 offers other multi-session features
such as split-screen viewing of any two sessions, labeling of each
session, session
status indicators, as well as copy and paste within and between connected
sessions. Although the sessions are independent, you can use common
features like setup, review previous lines, define key editor, and page
memory allocation, to name a few.
Compatibility
The VT520 is compatible with more than 30
operating systems, including VMS, OpenVMS, UNIX�, PICK�, MUMPS, and
Multi-user DOS. Included are 17 terminal emulations, such as Digital,
Wyse�, TeleVideo, and ADDS.
Ease of Use
The VT520 features an easy-to-use
Windows�-like setup, support for 25 languages and a choice of five setup
languages. All keys are programmable to eight levels, and contents are
storable in non-volatile memory.
Designed to meet international standards and to have a minimal impact on
the environment, the VT520 offers users advanced
functionality, ergonomic design, "best in class" performance and
a comprehensive three-year warranty.
The VT520 is part of a family of terminals which also includes the VT510
monochrome text terminal and the VT525 color multi-session text terminal.
The VT500 family of products is completely backwards and cross-compatible,
and is available to multi-vendor environments
requiring ANSI, ASCII or PCTerm protocol.
