The 3483 InfoWindow* II Modular Display Station is a mainframe system (ES/9000*, S/370*, etc.) display terminal that attaches to a variety of IBM host computers. The 3483 InfoWindow II Modular Display Station provides a wide range of features and price points to meet various customer needs. This series is offered in a range of models and features a modular design of a logic, a keyboard, models with no monitors, models with various IBM PS/2* and PS/ValuePoint* monitors.


  • Modular design: separate modular logic unit (floor/wall/desk mount) with user selectable IBM monitor
  • Support of some new IBM monitors for high screen resolution, 27 x 132 (mode 5) and 50 x 80 (twin screen) formats, and advanced power management
  • Support of IBM PS/2 Host Connect Keyboard
  • 3481/3482 compatible with enhancements: Dynamic color assignment for foreground and background colors, 195,000 Color palette, Record/Play enhancements, Security controls


The monitors supported by the 3483 include a 14-inch conventional color CRT, a 15-inch FST color CRT, and the 17-inch Trinitron** (TR) color CRT, the latest technology products. With an attachment of the new multi-frequency monitors, the 3483 provides improved ergonomics for increased user comfort.

  • Advanced power management that meets the power consumption requirements defined by the EPA "Energy Star" program, and by specification 803299 of the Swedish NUTEK organization.
  • ISO Standard 9241 Part 3 to provide users with display modes for flicker-free viewing of crisp, clear, bright, high-contrast text.
  • Swedish MPR-II guideline for low electric, magnetic and electrostatic emissions.

The 3483 also supports the IBM PS/2 Host Connect Keyboard which has both host (mainframe) and PC nomenclature on the keytops. This modular design concept allows the customer to maintain monitor and PS/2 Host Connect Keyboard investment when migrating to a PC environment in the future.

The 3483 is 3481/3482 compatible with enhancements. The enhancements include:

  • Dynamic color assignment of foreground and background color from a 195,000 color palette
  • Record/Play enhancements
  • Security control

Modular Design

The 3483 offers a modular design: modular logic unit, keyboard, and supports attachment of many IBM monitors.

Investment Protection - Upgradability Improvements

The modular design of the 3483 meets today's customers' various business needs and investment protection. It provides a choice of monitor that best fits into each customer's environment in terms of monitor size, color, ergonomics, price range, power management. It also supports the new 122-key IBM PS/2 Host Connect Keyboard which has both host (mainframe) and PC nomenclature. With the combination of the monitor choice and PS/2 Host Connect Keyboard, the customer can maintain an investment in both the monitor and the PS/2 Host Connect Keyboard if migrating to a PS/2 in the future. The 122-key IBM PS/2 Host Connect Keyboard will have a proper PC nomenclature for a PC environment.

Support of New IBM Monitors

When used with the applicable new IBM monitors advantages include:

  • Regulatory compliance
  • Advanced power management
  • Twin screen
  • High screen resolutions
  • High screen refresh rates

Business Solutions - Regulatory Compliance

The 3483 is designed to meet or exceed standards and guidances that have recently emerged for workstations.

  • MPR-II 1990:08 guidelines for Electromagnetic Fields (Swedish National Board of Occupational Safety and Health). The new stringent Swedish requirements for low frequency electric and magnetic fields as well as electrostatic fields from monitors. MPR-II includes:
    • Very Low Frequency Magnetic Fields (VLMF)
    • Extremely Low Frequency Magnetic Fields (ELMF)
    • Very Low Frequency Electric Fields (VLEF)
    • Extremely Low Frequency Electric Fields (ELEF)
    • Electrostatic Fields (ESF)
  • ISO 9241 Part 3 Visual Displays (International Organization for Standardization). Part 3 defines "Front of Screen" characteristics related to uniformity of presentation over the entire display area. Following are some items defined by ISO 9241 Part 3.
    • Character height
    • Character width-to-height ratio
    • Character format
    • Character size uniformity
    • Between - character spacing
    • Between - line spacing
    • Linearity
    • Orthogonality (squareness)
    • Brightness
    • Glare
    • Display luminance
    • Luminance balance
    • Luminance uniformity
    • Temporal instability (flicker)
    • Spatial instability (jitter)
  • DIN 66 234 VDU Workstations
    • Geometrical design of characters
    • Perceptibility of characters on Screens
    • Grouping and formatting of data
    • Coding of information
    • Principles of ergonomics dialogue design
The compliance to the ISO 9241 Part 3, DIN 66 234 and MPR-II depends on the monitor attached.

Business Solutions - Advanced Power Management

With the attachment of the applicable new IBM monitors, the 3483 supports an advanced power management feature. This feature is a multistage power management, and turns off components in the monitor not in use during periods of inactivity. It reduces the power consumption up to 90% and reduces component stress which results in a longer product life.

Stages of power management are:

  • Auto Dim - blanks the display screen after a period of inactivity thereby preserving the screen phosphor.
  • Standby - turns off deflection components which reduces power consumption up to 65%. Recovery takes approximately 1-2 seconds.
  • Inactive Standby - Turns off CRT cathode and filament which prolongs CRT life. This reduces power consumption up to 90%. Recovery takes approximately 3-5 seconds.

Some models feature a power management capability that meets both the power consumption requirements of the EPA (US Environmental Protection Agency) "Energy Star" program and the lower power consumption requirements defined in specification 803299 of the NUTEK (National Board for Industrial and Technical Development in Sweden).

End-User Productivity - Improved Worker Productivity

The twin screen mode is available with some new IBM Monitors. This mode displays two full 24 rows by 80-columns formats on the screen by top-bottom. One 24 x 80 format can be used online, and the other as reference. Customers can copy all or a part of the screen between online session and the reference area.

Dynamic Color Assignment

The 3483 allows a customer to select foreground and background colors out of 195,000 color palette.

End-User Productivity - Interoperability Improvements

Customers can dynamically select any preferable 7 foreground colors and 1 background color from 195,000 color palette. This can be selected by a local user setup panel.

Record/Play Enhancement

The 3483 record/play enhancements include:

  • Support of the local function keys (Calculator or Copy)
  • Insert delay in the playback sequence to communicate to the host

End-User Productivity - Improved Worker Productivity

The 3483 will enhance the record/play function. The local function keys such as Calculator or Copy etc., can be included in the record/play sequence. Also, a certain interval of delay can be inserted into the record/play sequence so that customers can perform play back with host interactions by suspending the play back while the host is busy. The 3483 acknowledges the host busy status, suspends the play back, and resumes when the host busy status is cleared.

The 3483 allows customers to have up to 6000 key strokes in total of record keys identical to the 3481/3482.

Expansion Cartridge

The expansion cartridge slot allows for possible future functional enhancements or to meet customers' unique requirements. The demonstration cartridge is available that allows the 3483 to be demonstrated at a customer's site without an attachment to a host.

Security Controls

The 3483 provides auto key-lock mechanism after being unattended for a certain time, and the key-lock should be released when a correct password is entered. The 3483 also has VPD (Vital Product Data) lock-out feature to inhibit customers to change VPD record.

3481/3482 Compatible Functions

  • Calculator
  • Host Addressable and Local (Screen/Trim) Print
  • Extended Vital Product Data (VPD)
  • Auto Dim
  • Rule Line
  • Record/Play/Pause
  • Cut & Paste

Customer Setup (CSU)

The 3483 and specify features are customer set up (CSU). CSU publications will be in English or National Language.
