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.
