The HP A At Work as a Data Entry Terminal

The HP 2640A CRT terminal is now being integrated into Hewlett-Packard's internal data entry and data communications system called COMSYS. A worldwide distributed network of minicomputer systems, COMSYS uses dial-up telephone lines to link 76 HP locations for the transfer of data. Currently over 150 CRT terminals of various types are being used to enter approximately three million characters of data per day. Total COMSYS traffic averages 40 million characters of data per day with peaks of over 100 million characters per day. The 2640A is being used as an operator-to-program interface with its primary COMSYS use being for data entry. Sales orders, shipping papers, payroll information, statistics and general messages are only a few of the kinds of data being entered into COMSYS via 2640A terminals. Each data entry transaction may require several forms or formats to be displayed sequentially on the CRT screen. As each format is displayed, the operator transposes coded data from a source...

IMAGE Data Base Access

Application programs access IMAGE data bases through a set of IMAGE system services. These services give the programmer high-level, applications-oriented data base access, without concern for where the data is stored or how it is accessed. Services are available to open and close a data base for access, obtain information about the data base, read all or some of the data items in a specific data entry, add a new data entry to the data set, update data item values in an existing data entry, delete a data entry from the data set, and lock and unlock the data base or a subset of it for temporary exclusive access. Using these services, programs can access the data base in one of four modes. Serial access retrieves successive data entries from the data set. It is often used to process an entire data set in one pass. Direct access retrieves data entries based upon their record locations within the data base. It is generally used when the application already knows the identity of the data...

Interfering Gas Compensation

The final correction applied to the PCO computation compensates for the errors caused by interfering gases (see box on page 16). Since the instrument is calibrated on a binary carbon dioxide and nilrogen mixture, the question is how to allow the operator to reduce the effect of the interference to acceptable limits and not compromise ease of use. It seems appropriate to allow the microprocessor to perform the correction computation, so the problem becomes one of simplifying the data entry. Three assumptions were made

Software Enhancements

Another special flag can be toggled during program execution, allowing the user to modify a program sequence during execution. The last special flag is a data entry indicator. The flag is set every time a STOP statement is encountered. Any manual data entry will reset this flag, but if the RUN key is pressed before a data entry, the flag will remain set. This can be used to terminate a string of data entries in a program.

IMAGE Data Base Structure

An IMAGE data base consists of data items, data entries, and data sets. A data item is a single piece of data, such as an employee number or employee name. A data entry is an ordered set of related data items, such as all the information about a particular employee. A data set is a named collection of data entries, such as the set of all information on all employees. A data base is a named collection of related data sets, such as all the data sets that relate to a payroll application.

By Robert G Nordman Richard L Smith and Louis A Witkin

The new terminal is a logical extension of the HP 2640A Terminal1, the first CRT terminal developed by HP and the first of a family of terminals. The 2644A was conceived as a terminal that would be less dependent upon the resources of the host computer and would be capable of significant data entry and text preparation applications totally without the aid of a supporting processor. Data entry is another application that has typically been the province of terminals requiring computer support. In general, a form is provided for the user at the terminal from the computer. The user then enters the data into the computer and it is subsequently printed on preprinted forms by the computer's line printer. With a 2644A Terminal in this application, the need for the computer disappears. Forms previously prepared on the terminal and stored on cartridges may be retrieved at the push of a button. The data is entered into the form, and may then either be printed directly or stored on a cartridge to...

An Easyto Use Chartmaker

HPEASYCHART does not use a file for data entry. Instead, the user selects a chart type and then enters individual data values to construct the desired output. This data entry method makes HPEASYCHART well suited for one-time applications, such as charts needed as illustrations in a text document or as presentation aids. Periodic charts with unchanging design specifications are more efficiently prepared using data files and a chartmaker like DSG 3000. Instead of presenting a confusing array of options, HPEASYCHART menus are uncluttered. A help menu is available with examples. Operating instructions are minimized by including sample data with each menu option. These samples not only instruct the user on correct data entry, but also serve as default values that allow the user to preview the output. New data overrides the sample values and the previewing function can illustrate how the chart has been altered. The technique of learning by example is used extensively throughout HPEASYCHART...

Interfacing to Model A

The man-machine interface is keyboard-and-menu-display, similar to Model 1610A Logic State Analyzer described in the preceding article. The CRT display is a raster-scan type for both the timing diagram and alphanumerics. Menus are called up by the keyboard and changes are made by moving a cursor to the desired location and pressing the appropriate data entry keys. The input lines can be labelled on the display to make it easier to format and evaluate data listings (Fig. 3).

Alphanumeric Features

In addition to all of its graphics features, the HP 2700 is a complete alphanumeric terminal compatible with the HP 2622A Data Entry Terminal. Applications that depend on block mode and format mode, such as VPLUS 3000, will run unchanged on the IIP 2700. There are new display enhancements that allow applications to make use of color in alphanumeric applications as well. The use of color on a menu or form allows the reader to discern much more information than is possible with a monochromatic display.

Digital System Details

The digital machine in the 3 571A is a 16-bit binary serial processor using 8K of ROM. It has four major functions the measurement routine, the data entry, the data output, and the calculation of the analog output. The data entry routine is primarily used to bring in data from the HP-IB for remote control of the 3571 A. The 3571 A, except for the power switch, is complete The controller also calculates an offset voltage to be subtracted from the log amp output so the analog output will correspond to the display. During the time that the controller is not in a measurement routine or data entry, the controller uses the digital-to-analog portions of the successive-approximation digitizer to construct an analog voltage. For a given display reference and input range, the number is constant so a follow-and-hold circuit can retain the analog voltage while the controller is occupied with the other routines. This analog signal is then added to the normal (straight through) analog output to...

Data Base Inquiry Facility

The data base inquiry (DBI) facility is used to access an IMAGE data base without an application program. It is particularly useful during application debugging to generate test data in the data base or examine data base contents. Data base inquiry is also useful for handling impromptu inquires into the data base, to display and summarize the data stored there. Using it, the user can display information about the data base structure, add data entries to a data set, delete data entries from a data set, modify data item values in a data entry, display the values of data items in selected data entries, and print data base inquiry responses on the printer. ADD EMPLOYEE DBI requests a value for each data item in the data entry, by name, on the screen. The data supplied in response is checked for validity before being stored in the data base.

Supporting Symbolic Math

One motivation for conservative translation was to maximize the perceived responsiveness of the system. In a highly interactive system wilh the range of processing speed available in a handheld environment, data entry and translation can occupy a large fraction of the overall processing time. A simple translation minimizes this operating overhead.

Digital Or Analog Recording Of Counter Measurements

Another important feature of the 562A Digital Recorder is the provision for dual input coupling. At a small additional cost, another rear input connector may be added to the instrument to permit data entry and simultaneous printing from two unsyn-chronii ed counters or other sources.

System Data Manag Ement Station

VIATRON'S System 21 is a family of data processing devices designed for data management, including data entry control, display, communication, storage and retrieval. With its modular structure, System 21 can be configured to perform a wide variety of data processing operations.

Boards and Connections

For the interconnect design of the large number ni individual circuits, manual design was ruled out. largely because of time constraints. A sophisticated design automation approach was selected to provide automated placement of components and routing of traces after initial data entry of schematic and mechanical information.

The Right Tool for the

Perhaps the HP 250's most singular commitment to human engineering is Its adjustable CRT display screen. It slides from side to side, swivels about a vertical axis, and tilts. This range of adjustment accommodates all preferences for screen position. For example, people wearing bifocals can tilt the screen just slightly downward to facilitate their viewing. Where there are lighting variations, slight angular adjustments can reduce distracting glare. Contrast can be varied to individual preference with an easy-to-reach knob. Soft Keys. Eight user-defined function keys are located along the bottom edge of the display screen. A changeable function message displayed above each soft key describes its present function. This allows ease of learning and convenience of operation, and reduces the likelihood of keystroke errors. Keyboard. Positioned at a proper height and angle, the HP 250's data entry keyboard is generously spaced yet simple and uncluttered. It closely...

Workspaces and Windows

A data communications port can be attached to any one of the workspaces at a given time. Data flow is to and from that workspace only other workspaces are unaffected. The data entry example in Fig. 3 illustrates how this feature is used. A data entry application program in the host computer first creates four workspaces in the 2626A terminal and attaches its host's data communications port to each workspace in turn to transmit a form to it. After it sends all the forms, il displays the workspace that has the first form and makes it the keyboard workspace so the user can begin entering data into the form. When the user presses the ENTER key, the program displays the second workspace with the next form

By John T Uebbing Peter B Ashkin and Jack L Hines

A new, small, rugged, alphanumeric LED display, the Hewlett-Packard type IFDSP-2000, now reduces the cost of using alphanumeric by minimizing needed supporting circuitry. Coupled with the recent availability of low-cost microprocessors and semiconductor memories, this should contribute to a rapid expansion in the use of displays with full alphanumeric capability (upper and lower case alphabet. numerals, and special symbols) where previously they have not been practical. Some of the potential applications for low-cost alphanumeric display systems are in calculators, portable computer terminals. data-entry stations, and other readout devices, all of which are becoming more common in business, medical, and telecommunications systems.

IMAGE Design Objectives

In achieving the first objective, concessions were made by reducing data entry sizes, data set capacities, and other specifications. The number of ways to open and access a data base was also reduced. Three of the eight DBOPEN modes were implemented this is sufficient to allow exclusive or shared data base access. In implementing four of the eight DBGET modes, the essential access methods (serial, direct, chained, and calculated) are supported.

Lm3914 Amateur Radio

HAL has just started shipping the units and the first users are getting on the air. I've seen the user documentation it is certainly comprehensive. At least two HF forwarding BBS implementors are adding CLOVER support, and HAL is interested in helping others to port software. With all that hardware on the card, plus software development to amortize, the cost of the PCI-4000 is a bit above the DSP-based TNCs, so I don't expect that everyone will have one. Still, if the card is as good in practice as it is on paper, I'd expect to see a substantial portion of HF forwarding traffic being sent by this mechanism by the end of 1993. Some of the RTTY AMTOR big guns are already trying this new mode. 'Raymond C. Petit, CLOVER-II A Technical Overview,

Barcode Wand Lens Photo Sensor Led

BAR CODES ARE A RAPIDLY CROWING method of manual data entry that can be used as an effective alternative to keyboards. A Liar code is a self-contained message with information encoded in the physical widths of bars and spaces in a printed pattern. Hewlett-Packard's new HEDS-3000 Digital Bar Code Wand Fig. 11 is a reliable interface between these printed bar codes and a digilal decoding system. When the handheld wand is used to scan the bar code, it converts the light reflected from the printed bars and spaces into TTL or CMOS-compatible logic levels. The resulting digital signal is available for input in a d gital decoding system. Fig. 2. The HEDS-1000 High-Resolution Reflectance Sensor used in the HEDS-3000 is also available as a separate product. This sensor contains both an emitter and detector in a single package. A bifurcated lens design focuses the light from the sensor's emitter onto the area to be sensed and focuses the reflected light back onto the defector area in the...

An Availability and Reliability Calculation Tool for Computer Systems

To make data entry easy and the output format clear and comprehensive, segmented windows on the screen prompt the user for input values and the soft keys are activated to browse back through Ihe data and edit it if needed. Results of the calculation can be inspected on the screen or can be printed in the form shown in Fig. 2. Here an abbreviation such as 2 1J means that out of n - 2 devices present only k 1 is needed for the system to be operational.

Set of Design Tools

The set contains three editors for entry of data. ED is a general-purpose text editor. ICS is a graphics editor used for the design of masks. DRAW is also a graphical editor but is used for schematic data entry rather than entering mask data. Both DRAW and ICS are described in other articles in this issue.

ToGHz Synthesized Signal Generator Has Internally Leveled Pulse Modulation

Crocomputer control provides keyboard operation, data entry from the front panel, digital sweep capability, and many other features. Calibrated output levels from -100 dBm to t8 dBm are available over the 2-to-18-GHz frequency range. Maximum power is +4 dBm to 22 GHz and 0 dBm to 26 GHz.

Designing the Applications Data Base Organization

IMAGE 250 provides a consistent way of accessing the data in the data base from all applications software modules. However, the initial design of IMAGE 250 provided for data entry only in string form. The applications development effort showed that a more effective way of breaking string into its data elements was needed. The IN DATA SET statement was invented to fill this need (see article, page 19).

The Evolution of Widgets

Athena widgets were keyboard traversal, a configurable menu system, and Preseniation Manager behavior Keyboard traversal is keyboard-only operation of the user interface without touching the mouse As an example, consider a property sheet or a data entry form that contains numerous fili-m-the-biank fields, tn the model presented by the Athena widgets, the user had to move the mouse every time there was a need to move to a different field Touch typists complained that reaching for the mouse interrupted them to such a degree that they felt the interface was unusable. By offering keyboard traversal, the CXI widgets provided a way to navigate through the interface without ever having to leave the keyboard.

SOS Technology Yields Low Cost HP Computer System

Like other HP 3000 Systems, the Series 33 runs under the Multiprogramming Executive (MPE III) operating system, including the recent additions of a new, friendlier user interface and private disc volumes. A new, easy-to-use data entry subsystem, VIEW 3000, is supported on both the HP 3000 Series 33 and the HP 3000 Series II III.

EW DATA ENTRY and program development capabilities are provided by a new HP CRT terminal, Model 262RA Display Station, which lets the user display, compare, and combine data from two different computers and four different memory workspaces simultaneously. The new terminal (Fig. lj has dual data communications ports for connection to computers or peripherals and the user can divide both the display memory and the display screen into as many as four independent work areas. Other features are line widths up to 160 characters with horizontal scrolling, screen-labeled softkeys, an optional built-in thermal forms-copy printer, programmable tones for audio cues, and keys for interactive Forms design.

Details of Operation

Two special entries are available for Model 5401A these can be selected by means of a switch on the interface control board. First, the very first data entry can be the starting channel number of the multichannel analyzer data. And second, after the final data entry, a SET FLAG-CONTINUE command can be entered by the interface. This can be used to cause a conditional branch in the calculator program.

User Definable Keys

Eight keys under the HP 250 CRT display can be defined differently in different applications programs to allow the operator to select various functions. The functions appear on the CRT above the keys. Also shown here is an example of a form in which data entry and display are programmed using standard input, enter, and disp statements. Fig. 1. Eight keys under the HP 250 CRT display can be defined differently in different applications programs to allow the operator to select various functions. The functions appear on the CRT above the keys. Also shown here is an example of a form in which data entry and display are programmed using standard input, enter, and disp statements.

Design Objectives

User sophistication varies considerably, from the data entry clerk to the very knowledgeable OEM customer. Each user needs to take advantage of a different set of features. A department manager of a data entry operation, f or example, needs to configure the terminal for use by dala entry clerks. The terminal provides configuration menus for this purpose. On the other hand, these configuration menus can be locked out and made unavailable to the clerks to avoid confusing them with details they don't need. To allow a user to draw simple bar charts without graphics capability, one of the terminal's character sets has been oxpanded to include appropriate characters. The forms-drawing keys make it easy to design data entry forms.

Friendly Syntax

The syntax for operating the instrument from the keyboard makes operation straightforward. Some examples of user convenience are short-form entry of addresses and data (omitting leading zeros), multiple consecutive data entry (holding down the ENTER key causes the same data to be loaded into successive memory locations), automatic incrementing of the address register when a data entry is made, and the single-step FWD and BACK keys.

Analog Output

Before conversion to analog form, the binary-coded-decimal numbers are first converted to binary in a BCD-to-binary converter. This converter drives the switches in a conventional 10-bit binary resistor ladder network which does the final conversion to a bipolar analog voltage. The final converter is a thin-film hybrid circuit containing the switches and thin-film resistor ladder network in one package. Manual Data Entry

Using Autoplot

Placing the AUTOPLOT disc in drive 1 and pressing the CHART TYPE key starts up the application and brings up a chart type display (Fig. 1). This serves as a home base from which all the major parts of the system can be accessed. The parts are data entry, chart format specification, text slide and labels, saving and recalling charts, combining charts, hard copy, and multiple hard copy. Pictures of the major chart types are used for selection of the type of chart to be created. The keyboard's thumbwheels are used to place the cursor on the picture of the chart type desired. Pressing the thumbwheel button brings up the interface required to con

Whats Inside

Arithmetic operations and temporary storage of data and instructions are accomplished in the nine internal registers indicated in Fig. 4. Eight of these are flip-flop (integrated circuit) registers. The ninth is a row of toggle switches for manual data entry. The contents of all but one of the flip-flop registers are available to the programmer, and are displayed on the front panel.

By A Peter Hamilton

Because the primary business applications are data intensive in contrast to the computational intensity of scientific applications, the HP 250's data base management software system is considered a significant contribution in a low-cost, entry-level system. Data base access is further enhanced through better data entry and reporting capabilities. These facilities, coupled with a powerful inquiry facility, provide easy access to timely information for better control of the business.

Return To Start

When 1 laid out my data transmitter, I used three 8-switch dip switches making for a maximum of 24 binary data entry possibilities. However, the digital tuner can use only 19 of the 24 switches. In an attempt to keep things positioned correctly for minimum data entry into the data transmitter, the binary printout is formatted with the four band hits shown on the left followed by the 15 main frequency divider bits. Spacing is provided between the switch groupings to aid user readability by matching the three blocks of switches. Because of the two-digit offset between the data transmitter switches and the tuner's register, adjusting the placement of the data bit pattern on the transmitter switches is required.

Barry Mathis

Applications for the HP 250 in larger companies tend to be departmental in scope and span a broad range of functional tasks. The HP 250 supports this type of need with powerful application tools in the IMAGE 250 data base manager, FORMS 250 data entry facility, REPORT WRITER 250 report production facility and QUERY 250 inquiry capability. These tools simplify the development of specific applications for departments of larger companies.

Human Factors

On the main alphanumeric keyboard, the arrangement of characters resembles that found on a typewriter. The philosophy here was that more people are familiar with a typewriter than with other alphanumeric keyboards, such as the teletypewriter. Keys have been added to this general arrangement to implement the full ASCII character set. Close cooperation among many HP divisions has resulted in this basic arrangement becoming a standard for a number of diverse data entry products.

The Toolkit

As mentioned above, the toolkit consists of three segments a converter, a compactor, and I O routines. VPRC, The vector-and-polygon-to-raster converter first converts vectors and polygons to a compacted form that has all of the transformations applied to it, that is, all scaling. clipping, rotating, and so on. It then rasterizes the compacted objects. The compacted data form has a fixed byte format, which means it is very easy to find the next object in the list. Unlike most vector-to-raster converters, this converter directly rasterizes polygons. This not only improves the process, but also makes it possible to fill polygons with raster fill patterns (binary patterns made by turning bits on and off).

By Timothy V Harper

Some other reasons for its popularity are the number of good application programs available for the operating system, CP M has been around a long time and a lot of programmers have had time to experiment with writing code that runs under it. Because it is a software development environment, it is naturally attractive to programmers. CP M also has a large installed base and is available on many different manufacturers' hardware. This means a big market for anything that a programmer writes.

Multiple Terminals

RPG-II 300 features an interactive multiterminal data entry extension that significantly expands the terminal accessing capability of RPG. Using this extension, an executing RPG program can accept data entered from one or more HP 300 application terminals or from the IDS. The system automatically enacts this facility by starting a dialogue with the user at the IDS before the program executes. At this time, the user tells the system which terminal or group of terminals is going to be accessed by the program. This capability can also be used dynamically to add a terminal to or remove 3. This data entry facility minimizes the number of times that the user's program must go through the source entry loop.

IMAGE Data Access

In general, access to data within a data base is carried out on the data entry level. That is. each call to a DBMS procedure accesses some or all of the data items within a data entry. The table below presents an outline of the parameter set. Some of the functions that can be accomplished through use of the DBMS procedures include adding a new data entry to a data set, deleting a data entry from a data set, reading some or all of the data items of a data entry, and changing the values of items of a data entry. In serial access, DBMS accesses the data entry whose entry number is one greater than the last until a data entry is located and read or until an end of file is encountered. When a data set is accessed by a program for the first time, a search begins at entry number one. Reverse serial access is also possible. Directed access is accomplished by an applications program's supplying an entry number. If present, the data entry with the specified entry number is read. If no such data...

Inside the A

The design of the dedicated operating program was constrained to use the four 9915A softkeys plus the shift key. Using relatively simple interaction with the 5180A. the 5181A can enable the 51 BOA so that the user can set recording parameters using the 5180A's data entry knob and then initiate action with the 5181A. To help the first-time user, the 5180A has pull-out instruction cards that indicate the correct operation of both the 5180A and the 5181A,
