Terminal
Types
Click
on your terminal type to view models and specifications.
Terminals are classified according to host
attachment.
ASCII -- Typically
attach to Unix, AIX, or Linux hosts (RS/6000,
Sun, DEC and others) via a RS/232 or RS/422
port found on the terminal. This port is
usually a D-shell 25-pin female connector.
Also attaches to other hosts that support
ASCII terminals. Popular models: IBM Infowindow
3151, Infowindow II 3153, and Wyse 55.
Twinax -- Attach
to a midrange host (AS/400, iSeries and
the like) via a twinaxial port found on the
terminal. Almost all twinax terminals can
be identified as such by the twinax "pigtail" that
attaches to the communication port. Also
known as 5250 devices.
Popular models: IBM 3197, 3476; Infowindow 3477,
3486, 3487 and 3488; I/O 2677-C, 2677-M; CLI 5476,
5488; Praim 5488+. Also worthy of mention is the CLI ET2000, a unique 5250 terminal that uses
ethernet cabling instead of twinax..
Coax -- Attach to a
mainframe host (S/390, ES/9000, Amdahl GS, etc.)
via a male coaxial connector (BNC type) found on
the terminal. Also known as 3270 devices. Popular
models:
IBM 3192, Infowindow 3471, 3472, 3481, 3482,
and 3483.
Ethernet Dumb Terminal -- Functions
as twinax, coax, or ASCII terminal, attaching
via ethernet cable in a TCP/IP network. Uses
TN5250e and TN3270e, and VT100 emulations.
This is a multi-protocol, simple substitute
for coax and twinax terminals. Example: CLI
ET2000.
Windows-Based Ethernet Terminals
and Thin Clients -- Attach to Windows
Servers (NT 4.0 Terminal Server, Windows Terminal
Services 2000/2003), IBM Midrange AS/40 (5250),
IBM Mainframe (3270), Unix/Linux (legacy serial
connections available on some models). A
highly-simplified alternative to the typical
network PC, where all software processing and
upgrades are done on a remote server.
