An all-points-addressable (APA) display provides a screen presentation of 720 x 384 picture elements in a viewable area of 240mm (9.4 in.) by 172mm (6.8 in.) and requires no color convergence adjustments. The new 3192 G models are compatible with the 3179 Models G10 and G20 in both alphanumeric and presentation graphics applications. Their workstation capabilities are significantly enhanced by a print buffer with line trimming capability which allows print support for local alphanumeric and graphic screen copy or host-addressable alphanumeric-only printer output. Host-directed printer support is addressed as a logical terminal. A 4201, 4202 or 5201 Model 2 monochrome printer or a 3852 Color Jetprinter Model 2 can be attached directly to the display or via a 3979 Expansion Unit for local alphanumeric and graphics screen copy, or host-directed alphanumeric-only print output. Operator set-up of bit switches on the underside of the keyboard selects either 6 or 8 lines per inch line pitch. For printer attachment requirements, see "Hardware Requirements" below. Depending upon the model, a Typewriter or Typewriter/APL2 keyboard, each with either 122 or 104 keys, is provided. The keyboards feature modifiable keycaps, 24 program function (PF) keys, improved cursor-move function keys, and a selectable field tab function key for light-pen detectable fields. The 104-key keyboards offer the user a shorter keyboard if a numeric keypad is not required. The modified keyboard layouts are defined by switches located on the underside of the keyboard (refer to "3192-G Color Graphics Display Station Operator Reference and Problem Solving Guide" (GA18-2591) for information) and can be set by the operator. The keyboard definition utility allows customer definition of three specific keyboard layouts. A keycap removal tool is standard so that the keycaps can be interchanged conveniently. The 3192 G models provide enhanced connectivity via the IBM Cabling System to an appropriate 3174 or 3274 Control Unit or Workstation Subsystem Controller of a 9370 processor without requirement for baluns. In addition, these models may attach to an X.21 leased/switched network via the 3174 or 3274. For attachment requirements, see "Hardware Requirements" below. Host interactive graphics support on S/370, 43XX, 303X, 308X, 3090 and 9370 processors is included in Graphical Data Display Manager (GDDM) Version 1 Release 4 or GDDM Version 2. Screen management functions are extended to interact with graphics information as well as alphanumeric information. One 3979 Expansion Unit can be attached to the display station to allow attachment of a 5277 Mouse and a 6180, 6184, 7371, or 7372 Color Plotter. When attached, the 3979 also provides the port for the 4201, 4202, 5201 Model 2, or 3852 Model 2 printer. OPERATOR FACTORS The 3192 G models have an etched screen, which minimizes glare and fingerprints. Indicators are displayed in symbols on the bottom row of the screen, outside the data area, and provide useful operator information. Updating the screen from the host is accomplished without refresh interruption (i.e., no blinking). An underline type cursor and a rectangular reverse video cursor, with blinking option, are provided. An enhanced full-screen cross-hair cursor or alternate cross cursor is featured for graphic operations. An audible alarm is provided to alert the operator. The volume of the alarm can be adjusted by the operator via switches on the keyboard underside. The video element may be tilted (4.4 degrees forward and 15 degrees backward), and may be rotated 180 degrees to change the screen angle for individual viewing comfort. The keyboard has a low profile, is lightweight, has textured keytops to reduce glare, attaches with a flexible coiled cable permitting operator positioning, and may be inclined at any of three angles (122-key: 6, 12 or 18 degrees. 104-key: 4, 12 or 18 degrees) for individual comfort. INPUT EDITING CAPABILITY Cursor move, tab, home key, back tab, insert, delete, extended erase (erase to end-of-field, erase all keyboard input data, and erase entire screen) and cursor select keys are all basic. All alphanumeric and special symbol keys have typamatic capability. Cursor move keys cause acceleration of the cursor when held down. Simultaneous depression of vertical and horizontal will cause diagonal movement. Fields of data can be selected by positioning the cursor, then using the cursor select key. If data fields are light pen detectable, the Selectable Field Tab function key will provide more rapid location. The 24 Program Function (PF) keys are provided on the keyboard in lower case mode. Entry assist is supported. The 3192 G models Entry Assist provides capabilities which facilitate operator entry and editing of text material. The capabilities include margins, tabbing, word-wrap, improved cursor positioning, improved character/word delete, cursor position indicator and an audible end-of-line warning tone. Entry Assist is intended for use primarily with a specific set of host editor programs. The 3192 G models provide a screen trimming function which enables the operator to set screen boundaries for both upper and lower screen lines, and left and right columns of the display for local screen print copy. The boundaries are independently set for both the 1920 (24 lines x 80 characters) or the 2560 (32 lines x 80 characters) screen sizes. The boundaries are independently saved until either updated by the operator or power is turned off on the 3192 G. At power-on, the boundaries are reset to the top and bottom lines and to the left most (column 0) and right most (column 79) columns of the display area.

Customers operating under ACF/VTAM with ACF/NCP over BSC lines must be at an ACF/NCP Version 3 or higher level. Customers should contact their service representative for PTF prerequisites including the following PTFs. - NCP V3 on 3705 - PTF UR12445 - NCP V3 on 3725 - PTF UR12446 - NCP V4 - PTF UR12444 - SSP V1R2.2 - PTF UR13293 - SSP OS/MVS - PTF UR13294 - SSP VM - PTF UR13295 o Printer Logical Terminal (LT) address must be assigned in the host software to support host directed printer output at the 3192-G workstation. COMPATIBILITY: o The 3192 G models are data stream compatible with the IBM 3179 Models G10 and G20. o The 3192 G models use only existing attachment interfaces. o Host directed printer data stream is compatible to the IBM 3287 Printer. As host-directed printing, the 3192 G models support alphanumeric data in 3270 data stream as an SNA Logical Unit type 1 (LU-1) printer, as an SNA Logical Unit type 3 (LU-3) printer, or as a non-SNA printer. See "Limitations" below. LIMITATIONS: o Category "B" terminals such as IBM 3277 Display Stations cannot be attached to a 3174 customized to support 3192 G models. o Plotters are only supported via IEEE-488 interface. o For host addressable printing, 3192 G models support the 3852-2, 4201, 4202, and 5201-2 printers as an SNA Logical Unit type 1 (LU-1) printer, as an SNA Logical Unit type 3 (LU-3) printer, or as a non-SNA printer with the following limitations: - APL2 is supported on 4201, 4202 printers only, - No Programmed Symbols (PS), and - Buffer size is 2K bytes maximum. o Existing alphanumeric applications will run on 3192 G models unless: - The program is affected by 3274 Control Unit restrictions (e.g., no Category B terminals); or - The program is affected by required display station configuration function restrictions not available with the 3192 G models (e.g., magnetic readers, light pen, triple-plane programmable symbols, encryption/decryption, or unsupported screen sizes). o The 3192 G models may attach to an X.21 leased/switched network via a 3174 or 3274 Control Unit. One IBM 3178, 3179-100, 3180-1, 3191, 3192, 3278, or 3279 display or 3270 PC operating in control unit mode is required as a network control terminal attached to the 3174 or 3274. o BSC Copy Command is not supported. o Programmable Symbols (PSA and PSB only) are supported in single color. PERFORMANCE: The 3192 G models will have performance characteristics similar to those of the 3179 G models. Use of the vector-to-raster conversion in the 3192 G models may offer graphics performance advantages as compared to the IBM 3279 Color Display Station Model S3G. Host processing service time will be reduced. It will now be more practical to run graphics applications on entry-level IBM 43XX and 9370 systems. The graphical output response time of the 3192 G models may be faster or slower than that of the 3279 Model S3G depending on the application, length, and content of the data stream. Customers should understand that special character fonts and complex graphic output composed of many short vectors increase the data stream length and require longer processing time in the 3192 G models than corresponding operations in the 3279 Model S3G. Host application programmers should be aware of the enhanced terminal functions provided by the 3192 G models to improve performance: o If the "area fill" function is specified to the terminal in lieu of being implemented by vectors from the host, the data stream content is simplified and performance is improved. o If programmable and image symbols are loaded in the 3192 G models storage, subsequent screen refresh due to graphic modification will improve performance by not invoking a symbol reload. o If the default vector symbols stored in the 3192 G models are utilized, performance is improved. However, excessive use of default vector symbols may result in longer processing time in the 3192 G models than corresponding operations in the 3279 Model S3G. When 3192 G model terminals are used for alphanumeric data only, they will have performance characteristics that are similar to other IBM 3270 display stations. For additional performance information, contact your IBM marketing representative. PLANNING INFORMATION The customer should have on hand, or should order, the IBM 3179-G/3192-G Color Graphics Display Station Description (GA18-2589) for site planning and preparation work.
