                                                        How to Use This Manual



Welcome!

Welcome to Screen Power, TeleSensory's new braille access software.  Screen 
Power has many advantages over other braille access software.  It is menu 
driven, so it is easy to learn.  Even computer beginners will be able to 
understand Screen Power's menu system.  And the on-line help system makes it 
possible to learn more about Screen Power on your own.

You can run all of Screen Power's functions and commands from the menu system.  
But that doesn't mean Screen Power is limited by the menu system.  Screen 
Power has a full set of built-in commands to do just about anything you need 
to do.  Use the menu system to change or add to these commands.  

Screen Power has many features that make it possible to customize commands and 
functions.  You can turn almost any menu function into a single keystroke or 
command using Screen Power's hotkeys.  Screen Power has sophisticated 
windowing and monitoring features that let you tailor the system to your 
application program.  The monitoring system looks for designated screen 
changes.  When they occur, you will automatically know and will therefore be 
able to respond appropriately and efficiently.  Our pre-set WordPerfect and 
Lotus 1-2-3 environments make working with these programs easy and efficient.  

Screen Power's integrated macros system is one of its most powerful features.  
Macros enable you to turn groups of commands into a single keystroke.  Screen 
Power macros can combine Screen Power commands, application program commands, 
and DOS commands to automate your computing functions to suit your needs.  


Manual Organization

Screen Power documentation is divided into four parts:

  Installation & Troubleshooting Guide: (this document) includes all 
  installation information, including a Quick Start Guide and a 
  Troubleshooting section.  Use the Installation Guide to install your Screen 
  Power system, including hardware and software.  This document is included in 
  print, on disk, and in braille.

  User Guide: is a step-by-step guide through Screen Power's features.  Use 
  the User Guide to learn about Screen Power.  It begins with basic concepts, 
  such as how to use basic navigation commands.  It continues with 
  intermediate and advanced usage, including how to use the menu system, how 
  to create hotkeys, place markers, and


  windows, and how to set braille options.  Each concept includes 
  step-by-step, hands-on examples.  This document is included in print, on 
  disk, in braille, and as an audio tape tutorial.  

  Menu Reference Guide: is an alphabetical guide to every Screen Power menu 
  item and concept.  Use the Reference Guide as you would a dictionary or 
  encyclopedia.  Every item is explained fully, including where it appears, 
  what its options are, what the defaults are, and how it is used.  This 
  document is included in print, on disk, and in braille.

  Command Summary: contains all Screen Power commands for both the 
  PowerBraille 40 hardware and Navigator hardware.  This document is included 
  in print, on disk, and in braille.

You should also refer to the README.TXT file on your Screen Power diskette.  
This file contains last-minute changes or additions to the product that may 
not be included in the rest of the documentation.  

You can use the SPBREAD.COM utility to read these documents on disk.  Each 
document file has a .TXT extension.  The four document files are:

  INSTALL.TXT           Installation & Troubleshooting Guide (this document)
  USERGDE.TXT           User Guide
  MENUREF.TXT           Menu Reference Guide
  CMMDSUM.TXT           Command Summary

Type SPBREAD followed by the filename.  For example, to read the disk file for 
the Installation Guide, type SPBREAD INSTALL.TXT.  For complete information 
about the SPBREAD utility, please refer to Appendix A of this document.


What's In the Package?

This product comes in two configurations: the PowerBraille 40 hardware and 
software package, and the software-only upgrade for the Navigator hardware.  
The Screen Power Braille software is identical in both packages.  Screen Power 
will give you access to the screen information displayed by an IBM or IBM 
compatible computer.

Typographical Conventions

The Screen Power documentation uses some simple typographical conventions.

Key names are italicized and referred to by the upper case print names from 
the standard keyboard.  For example, the Escape key is referred to as ESC.



Text or alphanumeric keys to be pressed are usually referred to within quotes.  
Do not type the quotes unless told specifically to do so.

Screen displays are usually indented on a line by themselves or displayed 
within quotes.  All screen displays are shown as they would appear on the 
normal unenlarged screen.  

File names are always shown in upper case bold print (i.e., FILENAME.TXT)

Where two keys should be pressed simultaneously, the keys are shown in upper 
case separated by a hyphen.  For example, CTRL-N means press the CTRL 
(CONTROL) key, hold it down, press the "N" key, and release both 
simultaneously.

                                                             Quick Start Guide


This Quick Start Guide is designed for people who are familiar with computers 
and refreshable braille systems.  If you do not fall into this category, 
please go directly to Chapter 1.  

1.    Set up PowerBraille 40 hardware: Connect PowerBraille 40's power supply.  
      Connect the parallel or serial interface cable to PowerBraille 40 and 
      your computer.  If you use the parallel connection, be sure to note 
      whether PowerBraille 40 is connected to LPT1 or LPT2.  If you use a 
      serial connection, note whether PowerBraille 40 is connected to COM1 or 
      COM2.  You do not need to have the PowerBraille 40 hardware connected to 
      run the installation program.

      If you have Navigator hardware: If you purchased the Navigator upgrade 
      package, you can only connect Navigator to a serial port.  Connect the 
      Navigator power supply and serial cable, noting whether the serial 
      interface is connected to COM1 or COM2.  You do not need to have the 
      Navigator hardware connected to run the installation program.

2.    Install software: You will need up to 500K available on your hard drive 
      to store the Screen Power files, and about 50K RAM (conventional memory) 
      to run Screen Power.  Most of the program swaps into expanded or 
      extended memory or into a swap file on your hard drive, but you will 
      still need about 50K of RAM.

      Type INSTALL from the A or B drive to run the installation program.  
      Follow the prompts to specify the port your PowerBraille 40 or Navigator 
      is connected to, accept or change the default directory of \SPB and use 
      the C drive as the start-up drive.  The installation program will create 
      a batch file called SP.BAT to run Screen Power.  If you want Screen 
      Power to start automatically whenever you turn your computer on, tell it 
      you want to modify the start-up files.  Screen Power will use the DOS 
      "CALL" statement to run the SP.BAT file.  Otherwise, you must type SP to 
      load Screen Power manually.

      Swapping Screen Power to Expanded or Extended Memory: During the 
      installation process, you will be asked to select a swap option for 
      Screen Power.  It can swap to expanded or extended memory or to a disk 
      file on your hard drive.  (If you don't have at least 120K of expanded 
      or extended memory or 200K of hard drive space, all of Screen Power will 
      go into conventional memory.)  Swapping adds a variable to the SPB 
      command line in


      the SP.BAT file.  The SP.BAT file will accept up to four variables.  The 
      following command-line options exist for swapping:

      /F    Swaps Screen Power to a disk file on the hard drive

      /T    Swaps Screen Power to extended memory

      /X    Swaps Screen Power to expanded memory

      Using View2: During the installation process, you will be asked if you 
      want to use View2, TeleSensory's on-line Grade 2 translation program.  
      If you choose to load View2, the installation program will add the line 
      SPView2 to the SP.BAT file, just before the file loads SPB.  This 
      program uses an additional 60K of conventional memory, which cannot be 
      swapped to extended or expanded memory, but can be loaded high.  View2 
      allows you to use a panel key hotkey to instantly translate your screen 
      information to Grade 2, where it is displayed on your PowerBraille 40 or 
      Navigator.  You can then type on the computer keyboard and have your 
      text translated to Grade 2 as you type, or you can use the computer 
      keyboard as a braille keyboard and input in Grade 2 directly.

      Modify AUTOEXEC.BAT File: You will also be asked if you want to modify 
      the AUTOEXEC.BAT file.  If you do, the installation program will add the 
      line CALL SP to the end of the AUTOEXEC.BAT file.  

3.    Install manual files: Screen Power documentation files are located on a 
      separate disk, which has an installation program similar to the Screen 
      Power installation.  Follow the prompts to install the manual files in 
      the directory of your choice.  The manuals are all in ASCII text format.  

4.    Running Screen Power: If you told the installation program to modify 
      your start-up files, you must reboot your computer to activate the 
      change to the AUTOEXEC.BAT file.  Screen Power will then load 
      automatically.

      If you did not choose to modify the AUTOEXEC.BAT file, you do not need 
      to reboot your computer.  You must type SP at the DOS prompt to load 
      Screen Power.  

5.    Next Step!  If you are unfamiliar with refreshable braille systems, you 
      should refer to Chapter 1 of the User Guide to introduce you to Screen 
      Power's navigation commands.  This chapter also introduces use of Grade 
      2 braille and 8-dot braille with Screen Power.  If you are already 
      familiar with the above concepts, you should go directly to Chapter 2 of 
      the User Guide.  It is titled "Intermediate Usage," and is geared for 
      those who have mastered the basics of Chapter 1.  It includes 
      information on the menu


      system, the on-line help system (activated in the menu system with the 
      F1 key), and such features as customizing panel keys, hotkeys, and place 
      markers, and setting braille options.





                                                       Chapter 1: Installation


This chapter describes how to install your PowerBraille 40 system: the 
PowerBraille 40 hardware and the Screen Power Braille software.  This chapter 
is divided into two sections: Hardware Installation and Software Installation, 
including installing the manual files on your hard drive.  If you purchased 
the Navigator upgrade package, you should already have your Navigator set up 
and ready to run.  If so, you can skip the hardware installation and go 
directly to the software installation section on page 12.  

Read through the directions once before you start and be sure you understand 
all the steps involved.  If you have any questions or are unsure of what to 
do, contact TeleSensory Technical Support at 1-800-537-3961.


PowerBraille 40 Hardware Description

The following is a brief physical description of the PowerBraille 40 hardware.  

      Top surface controls are a 40-cell braille display with a tactile button 
      above each cell, and two push-buttons, one at each end of the braille 
      display.  There is also a tactile ruler with indicator dots below each 
      braille cell.  

      Front panel controls from left to right are left rocker bar, convex key,

Battery Usage Status Displays

The PowerBraille 40 has internal NiCad rechargeable batteries located inside a 
panel on the bottom of the unit.  These batteries charge automatically while 
the power adaptor/charger is plugged in.  There should be no need for you to 
remove or replace these batteries.

If PowerBraille 40 is off, but you have the power supply plugged in, the unit 
will display a battery usage status message in North American computer 
braille.  This is because whenever the power supply is connected and the power 
switch is off, PowerBraille 40 is charging.  The status message shows usage in 
hours, minutes, and seconds, and will look something like this:

  battery usage 00:07:35, fast charge on

The battery usage information is an indication of how long the unit has been 
run on battery power.  The above message means you have used the unit for 7 
minutes and 35 seconds on battery power.  Whenever there is any time showing 
on the battery usage status, PowerBraille 40 will use a "fast charge."  While 
fast charge is on, the battery usage time will tick down until it reaches 
zero.  At that point, the "slow charge" begins.  The message will then be:

  battery usage 00:00:00, slow charge on

This message will remain displayed until you turn on the unit or remove the 
charger.  You should always turn the PowerBraille 40 hardware on either before 
or at the same time as your computer.  

Whenever you turn on the PowerBraille 40 hardware without turning on the 
computer, the PowerBraille 40 unit displays its name, version number, and 
battery usage status.  The display will look something like this:

  Braille 40 v4.0a, battery usage 00:00:35

The characters after the letter "v" tell you which version it is.  This 
message will appear whenever you turn on the unit, whether the power supply is 
connected or not.  

IMPORTANT NOTE:  PowerBraille 40 goes into a "sleep mode" to conserve energy 
whenever you are not using it.  After 4 minutes of inactivity, the braille 
characters fade away temporarily.  They gradually become mushy as all dots 
rise, until all dots in all cells are up.  This is the "sleep" mode for 
PowerBraille 40.  As soon as you press any key, the cells go back to their 
"awake" position.  However, the key you press does not take effect on the 
computer.  It just wakes up the cells.  You must press the key again to have 
PowerBraille 40 execute its function.

PowerBraille 40 Hardware Setup




This section provides instructions for setting up the PowerBraille 40 
refreshable braille hardware.  If you purchased the Navigator upgrade package, 
you should have your Navigator hardware already set up.  If so, skip directly 
to the next section on software installation.

1.    Attach the PowerBraille 40 power supply cable to the display unit.  This 
      connector is on the back panel near the left side (as you face the rear 
      of the unit).  Plug the other end into a wall outlet or power strip.

2.    Connect the parallel or serial cable to the back of the PowerBraille 40 
      display unit.  

      Serial connection: There are two 9-pin serial connectors, one female and 
      one male.  If you want a serial connection to your computer, you must 
      use PowerBraille 40's 9-pin female port.  Connect the male end of the 
      serial cable to this female port.  Connect the other end of the cable to 
      either COM1 or COM2 on your computer.  Remember whether you are using 
      COM1 or COM2 so that you can tell the Installation program.  The 
      Installation program default is COM1.  The male connector on the 
      PowerBraille 40 unit is for use with TeleSensory's BrailleMate portable 
      braille notetaker.  

      Parallel connection: The parallel connector is a 25-pin male port.  
      Connect the female end of the parallel cable to PowerBraille 40's 
      parallel port.  Connect the other end of the parallel cable to your 
      computer's parallel port, either LPT1 or LPT2.  Remember whether you are 
      using LPT1 or LPT2 so that you can tell the Installation program.  

3.    Place your laptop computer or desktop computer keyboard on the 
      PowerBraille 40 hardware unit directly behind the braille display strip.  
      You can use the enclosed Velcro strips to make a more secure attachment.  
      Be sure the rest of your computer system is completely set up, with all 
      components connected and verified to be working properly.


Screen Power Software Installation

Your system must be running DOS Version 3.3 or later.  You will have two 
3-1/2" diskettes and two 5-1/4" diskettes, one of each labelled "Program" and 
one of each labelled "Manual."

The Screen Power Program Disk you receive has compressed files on it.   During 
the installation process the files will be "uncompressed" and placed on your 
hard drive in usable format.  If you have questions about the files on your 
disk, complete the software installation process so that the files are 
restored.  Then you can look at all of them.  



Note: It is possible to install the software without having your PowerBraille 
      40 (or Navigator) hardware installed, but it is not recommended.  

You will need up to 500K (kilobytes) available on your hard drive to store the 
Screen Power program and manual files.  You will also need about 50K available 
RAM (or conventional memory) to run Screen Power.  

If you experience any problems during the installation process, please call 
TeleSensory Technical Support at 1-800-537-3961.  


Using View2 Grade 2 Translator

During the installation process, you will be asked if you want to install 
SPView2, TeleSensory's on-line Grade 2 braille translation program.  SPView2 
allows you to use a panel key command to instantly translate your screen 
information to Grade 2 braille, where it is displayed on your PowerBraille 40 
or Navigator.  You can then type on the computer keyboard and have your text 
translated to Grade 2 as you type.  

If you choose to load SPView2, the installation program will add the line 
SPVIEW2 to the SP.BAT file, just before the file loads SPB (SPView2 must be 
loaded before Screen Power is loaded).  This program uses an additional 60K of 
conventional memory, which cannot be swapped to extended or expanded memory, 
but can be loaded high.

If you are using a 386 or higher computer running DOS 5 or later, you can 
conserve the use of conventional memory by placing the following 3 lines in 
your CONFIG.SYS file:

      DEVICE=HIMEM.SYS
      DEVICE=EMM386.EXE NOEMS
      DOS=HIGH,UMB

This reduces View2's use of conventional memory to about 20K.  When less 
conventional memory is used, you will have more room for running DOS programs.  

Note: If you are upgrading a Navigator from Gateway to Screen Power Braille, 
      you must use SPView2 instead of the View2 program that came with your 
      Navigator.


Using Extended or Expanded Memory

Screen Power is designed to use about 120K of expanded or extended memory or a 
200K swap file on your hard drive, leaving only about 50K of the program in 
conventional memory.  This frees up more conventional memory for running other 
applications.  (If you don't have the necessary expanded, extended, or hard 
drive space, all of Screen Power will go into conventional memory.)  




Conventional Memory

Conventional memory is the first 1MB (1024K) of RAM (random access memory).  
DOS only allows you to use the first 640K of this memory, though, and reserves 
the rest for other tasks, such as video memory.  Today's application programs 
often use most of that 640K (for example, WordPerfect 5.1 uses over 400K), 
leaving little for access programs and other memory-resident programs such as 
Screen Power.  


Extended Memory

You can have extra memory installed in your computer.  Memory over 1MB is 
called extended memory.  DOS does not use or recognize this memory by itself.  
Screen Power will use any extended memory installed in your computer as a swap 
area if you tell it to.  


Expanded Memory

Expanded memory requires a memory management tool that lets applications be 
loaded above 640K but below 1MB, in a section of memory that passes 
information through a "frame" into extended memory.  Memory managers, such as 
QEMM and EMM 386, convert extended memory into expanded memory.  When a 
program uses expanded memory, the memory manager swaps unused parts of the 
program out of conventional memory and into expanded memory, then back again 
as needed.  Not all application programs can use expanded memory.  Screen 
Power uses expanded memory as a swap area if you tell it to.  


Disk Memory

Some programs can be swapped to a disk file on the hard drive.  The disk file 
works the same way expanded and extended memory do.  Screen Power uses disk 
memory as a swap area if you tell it to.  


Screen Power Memory Swapping

Three ways are available to load Screen Power: disk file memory, extended 
memory, and expanded memory.  A question in the installation program prompts 
you to choose one of these methods.  This will add a variable to the SPB 
command line in the SP.BAT file.  The SP.BAT file will accept up to four 
variables.  The swapping command-line variables are:

      /F    Swaps Screen Power to a disk file on the hard drive

      /M    No swapping (takes about 400K of conventional memory)

      /T    Swaps Screen Power to extended memory

      /X    Swaps Screen Power to expanded memory



You will not need to use one of these options unless you change the swapping 
option after you complete the installation process.  When you choose one of 
the swapping types, the install program automatically adds the appropriate 
option to the SPB command line in the SP.BAT file.  For example, the default 
selection is to swap to a disk file, so the install program adds the /F option 
to the SPB command line.  Therefore, every time you run the SP.BAT file, 
Screen Power enables disk file swapping and uses only about 50K of RAM.  

Note: Screen Power Braille cannot be loaded high.


Other Command Line Options

Command line options exist for specifying the communication port (COM1, COM2, 
LPT1, or LPT2) that the braille display unit is connected to:

      /Cn   (where n is 1 or 2) Specifies which serial port, COM1 or COM2, 
            Screen Power should use

      /Pn   (where n is 1 or 2) Specifies which parallel port, LPT1 or LPT2, 
            Screen Power should use

You will not need to use one of these options unless you change the port 
PowerBraille 40 (or Navigator) is connected to after you complete the 
installation process.  The installation program automatically adds each item 
to the SP.BAT file it creates.  

Two command line options exist for enabling and disabling Screen Power during 
operation:

      /D    Disables previously loaded copy of Screen Power

      /E    Re-enables Screen Power after a /D

Note: You can use the /D option while Screen Power is running by typing SPB /D 
      whenever you want to disable Screen Power's operation.  The /D option 
      disables Screen Power but does not remove it from memory.  Type SPB /E 
      to enable it again.  


Using the Installation Program

1.    Starting the Installation Program

      Start from the DOS prompt, usually C:\>.

      Put the Screen Power Program diskette in drive A or B.

      Type A: or B: and press ENTER.   

      Type INSTALL and press ENTER.

      The computer displays a screen with two menu items welcoming you to the 
      installation program and asking you if you want to


      install or exit.  Press ENTER to continue with the installation.  Press 
      X to abort the installation.

      Note: You can press CTRL-C at any time to abort the installation.

2.    Entering Your Name

      The program asks for your name.  A name can consist of any characters 
      (except %, the percent sign), but it must include at least one 
      alphabetical character.  The name you enter will be displayed on the 
      computer screen and the braille display each time you load Screen Power.  
      You will then be asked to confirm your name.  Press ENTER to confirm, or 
      press the DOWN ARROW, then ENTER to input a new name.  

3.    Specifying Communication Port

      You must specify which communication port (on the computer) your 
      PowerBraille 40 (or Navigator) is connected to.  For PowerBraille 40, 
      this can be either a parallel or a serial port.  The choices are COM1, 
      COM2, LPT1, and LPT2.  COM1 and COM2 refer to your computer's serial 
      ports; LPT1 and LPT2 refer to its parallel ports.  The default is COM1, 
      which is listed first.  Press ENTER to select COM1.  Use the DOWN ARROW 
      key to move to any of the other options.  When you make your selection, 
      Screen Power adds the information to its start-up command so that it 
      knows where to send information.  

      If you are using the Navigator hardware, you can only use serial 
      communication, so you must specify either COM1 or COM2.

4.    Creating a Directory

      The installation program asks if you want to install Screen Power in the 
      default directory or if you want to choose your own directory.  Unless 
      you have some particular reason to want your Screen Power files 
      elsewhere, press ENTER to accept the default directory, C:\SPB.  

      If you want to specify another drive or directory, backspace over the 
      current entry, then type the full drive and directory name and press 
      ENTER.  If the directory you entered already exists, the install program 
      warns you that Screen Power files may replace files that already exist 
      in the directory.  Press ENTER to type in a new directory.  

      The install program copies the correct files to the selected directory 
      in your hard disk and uncompresses files.  This may take a few minutes.  

5.    Installing On-line Grade 2 Translator

      The installation program asks you if you want to install SPView2, 
      TeleSensory's on-line Grade 2 braille translation program.  Press


      the ENTER key to install SPView2.  Press the DOWN ARROW key and then the 
      ENTER key if you do not want to install View2.  For more information 
      about View2, see the section earlier in this chapter titled "Using View2 
      Grade 2 Translator."  

      Note: If you are upgrading a Navigator from Gateway to Screen Power 
            Braille, you must use SPView2 instead of the View2 program that 
            came with your Navigator.

6.    Selecting Swap File Options

      Screen Power must be loaded with a swap option.  This means part of the 
      Screen Power program will reside in extended or expanded memory or swap 
      to a disk file on your hard drive.  Three options exist: swapping to a 
      hard drive file (adds the /F option to the SPB command line), swapping 
      to extended memory (adds /T), and swapping to expanded memory (adds /X).  
      If you do not understand these options, read the section called "Using 
      Extended or Expanded Memory" earlier in this documentation.  

      The installation program defaults to the swap to disk option.  If you 
      want this option, just press the ENTER key.  If you want one of the 
      other swap options, use the DOWN ARROW key to move to the one you want, 
      then press ENTER.  

7.    Modifying Your Computer's Start-up Files

      The next screen in the installation program asks if you want to add a 
      command to load Screen Power from within your AUTOEXEC.BAT file, which 
      is executed automatically each time you start your computer.  

      If you want Screen Power to start automatically when you turn on your 
      computer, you should select the default "Modify Start Up Files."  Select 
      the "Modify" option by pressing ENTER.  The installation program will 
      modify your AUTOEXEC.BAT file by adding the line CALL SP to the line 
      after the "PATH" statement.  Before modifying this file, the 
      installation program makes a copy of your current AUTOEXEC.BAT file, 
      which it names AUTO$$.SP.  The DOS "CALL" function runs a batch file 
      from within another file.  In this case, it will run the SP.BAT file 
      from within the AUTOEXEC.BAT file, returning to the AUTOEXEC.BAT file 
      when it is done.  

      If you don't want Screen Power to start automatically when you turn on 
      your computer, you should select the "Do Not Modify Start Up Files" 
      setting.  To make this selection, press the DOWN ARROW key, then press 
      ENTER.  



8.    Selecting the Start-up Drive

      If you chose to modify the start-up files, the installation program now 
      needs to know which drive you use to start up your computer (if you 
      chose not to modify the files, the installation program will not ask you 
      this question).   Normally, this is drive C.  If you have a standard PC 
      configuration, press the ENTER key to accept the C drive.  If your 
      start-up drive is not C, enter the letter of your start-up drive, then 
      press ENTER.  (You do not need to backspace over the existing drive 
      letter.  Just enter the new drive letter, then press ENTER.)  

      Note: Screen Power will not install to a floppy disk.  

9.    Completing the Installation

      You have now completed the installation.  A final screen tells you to 
      press any key to exit the installation program.  When you do that, you 
      will go back to the DOS prompt in your start-up drive.  

      Screen Power creates a batch file called SP.BAT that runs the correct 
      Screen Power files.  This batch file will be in both the root directory 
      and whichever Screen Power directory you designated (the default is 
      \SPB).  

      If you chose to have the installation program modify your start-up 
      files, Screen Power tells the AUTOEXEC.BAT file to automatically run the 
      SP.BAT file instructions, then return to the AUTOEXEC.BAT file to 
      execute any further instructions.  Before this can be activated, you 
      must turn off your computer, then turn it back on again, to activate the 
      change in the AUTOEXEC.BAT file.  Don't forget to remove the program 
      disk from the drive.  

      If you did not choose to have the installation program modify your 
      start-up files, you must execute the SP.BAT file some other way, either 
      by including it in your own batch file or by manually entering the 
      command SP from the DOS prompt.  


Congratulations!

You have successfully installed your Screen Power system.  See the next 
section, "Starting Screen Power," for instructions on how to run Screen Power 
when you turn on your computer.


Starting Screen Power

If you chose to have the Screen Power installation program modify your 
start-up files, then Screen Power will start automatically whenever you turn 
on your computer.  

If you did not modify the AUTOEXEC.BAT file, you should type 

      SP



and press ENTER now to load Screen Power.  You will need to do this whenever 
you turn on your computer.  Screen Power will load and display its start-up 
message.  


Installing Manual Files

The text files on your Manual Diskette are compressed.  There is an 
installation program on the Manual Diskette that expands the files and copies 
them to your hard drive.  This installation program is structured like the 
Screen Power software installation program you just used.  It is not necessary 
to have Screen Power installed and running while you install the manual files, 
but if you do, you can rely on Screen Power's braille prompts.  

Follow the prompts to put the files on your hard drive.  The install program 
will put the manual files in the default Screen Power directory (\SPB) or 
another directory if you prefer.  When you are finished, the files will all 
have a .TXT extension.  You can use the DOS TYPE command, the SPBREAD.COM 
program included with the program disk, or your word processor or text editor 
to read the files.  Please refer to Appendix A: Screen Power Utilities for 
information about the SPBREAD utility.  


Using Screen Power with Other TeleSensory Products


Using Screen Power With OsCaR

To use Screen Power with TeleSensory's OsCaR optical character recognition 
system, you must have OsCar version 3.1a or later.  You will probably need to 
upgrade your OsCaR to the latest version to have compatibility with Screen 
Power.  Call TeleSensory's Customer Service at (800) 227-8418 for details and 
latest information.  


Using Screen Power With Other TSRs

Whenever using Screen Power with other TSRs (Terminate and Stay Resident 
programs), it is best to run Screen Power last.  Any TSR larger than 175K run 
after Screen Power risks being swapped out when Screenpower swaps.  In other 
words, Screen Power prefers to be last.  If you experience any problems with 
Screen Power while other resident programs are running, try loading the other 
programs before Screen Power.  






                                              Chapter 2: Technical Information


Specifications for PowerBraille 40 I/O Ports

PowerBraille 40 has two serial ports and one parallel port.  



Port Type  Connect To   Type & GenderDefault Baud RateFixed or Changeable

DCE        Primary computer connection9-pin female9600Fixed

DTE        BrailleMate or second computer9-pin male4800Changeable

Parallel   Primary computer connection25-pin maleN/AN/A

How to Change the DTE Port Baud Rate

You can change the baud rate of PowerBraille 40's DTE port to 9600 baud for 
the current working session only.  Do this by pressing and holding cursor 
routing button 40 (the last cursor routing button) while powering on the unit.  

This is not a toggle command.  The unit will stay at 9600 for the current 
working session.  As soon as you turn the power off to the PowerBraille 40 
unit, the baud rate for the DTE port will revert to 4800 for the next working 
session.  


PowerBraille 40 Self-tests

The PowerBraille 40 refreshable braille display unit has several power-on 
self-tests.  Below is a brief description of each.


Braille Cells Test

To test PowerBraille 40's braille cells, hold the left rocker bar UP while you 
turn the power switch to the ON position.  The braille cells will all go up 
and down eight times.  The first time they will end with all cells up.  The 
next time they will end with all cells down.  This sequence will be repeated 
until you turn the unit off.  
Keypad Test




To test PowerBraille 40's panel keys, press and hold the concave key while you 
turn the power switch to the ON position.  The unit will display the message: 
"keypad test mode."  

Within 25 seconds, press each panel key once (press the rocker bars both up 
and down).  If they are all working properly, the unit will display the 
message: "keypad test ok."  

If you press more than one key at a time, PowerBraille 40 will display the 
message "keypad test error."  If you do not press all the keys within 25 
seconds, PowerBraille 40 will display the message "keypad test time out."  
This is also the message you will get if one of the keys is bad.  

To end the test, turn the unit off.  


Sensor Switches Test

Note: The sensor switches are the raised tactile dots above each braille cell.  
      In the Screen Power documentation, we refer to these as cursor routing 
      buttons.

To test PowerBraille 40's sensor switches, press and hold the right rocker bar 
DOWN while you turn the power switch to the ON position.  The unit will 
display the message: "sensor switch test."  

Wait until all the pins on all cells are down.  Then press each sensor switch, 
one at a time.  It doesn't matter what order you press the sensor switches in, 
but you must press them all within about 15 seconds.  As you press each sensor 
switch, all eight dots will come up in the cell.  When you press the last 
sensor switch, the unit will display the message: "sensor switch test ok," and 
all dots will go down.  


Removing and Charging the Battery

It should never be necessary to remove or charge the PowerBraille 40 internal 
battery.  This NiCad (nickel-cadmium) battery automatically charges whenever 
the power supply is plugged in and the unit is off.  Even if there is no 
battery power left in the unit, you can still use it with the power supply.  
It will go from no charge to fully charged in less than 7 hours.  

WARNING!!         In an emergency, you can use alkaline batteries to supply 
                  power to your PowerBraille 40.  If you use alkaline 
                  batteries in the PowerBraille 40, you must NEVER plug in the 
                  AC Adaptor (the charger unit).  This will cause PowerBraille 
                  40 to overheat and severely damage its internal circuitry!  
                  This will void your warranty!!



If you ever do need to remove the battery, follow the instructions below.

1.    Be sure PowerBraille 40 is off and the power cord is not connected.  

2.    Turn the unit upside down.

3.    The battery is housed inside a long, rectangular plate on the bottom of 
      the unit.  The plate is held in place by two Phillips-head screws, one 
      on either end.  Remove these two screws.  

4.    Gently lift the plate out from the PowerBraille 40 unit.  The battery is 
      attached to the underside of the plate, in a protective sleeve.  Two 
      wires go from the battery pack to the inside of the unit.  DO NOT REMOVE 
      OR DISCONNECT THESE WIRES.  

5.    Lift the batteries out of the sleeve.  Note the embossed icons on the 
      inside of the plastic sleeve, under the batteries.  These icons indicate 
      the correct orientation to insert each battery.  

To replace the batteries, orient each battery according to the icons in the 
plastic sleeve, and secure the panel in place with the same screws.  If you 
have new NiCad batteries, allow them time to fully charge.  

If you ever need to replace the batteries in an emergency, use four 1.5V 
C-size alkaline batteries.  Be sure to replace them with four 1.5V NiCad 
batteries before plugging in the AC adaptor.  If you plug in the AC adaptor 
with alkaline batteries inside, PowerBraille 40 will overheat.

You do not need to remove the NiCad batteries to charge them.  These batteries 
charge automatically while PowerBraille 40 is off and the charger/adaptor is 
plugged into an outlet.  The braille display shows the power usage while it is 
charging.  The numbers count down to zero (in hours, minutes, and seconds).  
When the numbers reach zero, the unit is fully charged.  


Trouble-shooting Information

The following information is intended as a guideline if anything goes wrong 
with your Screen Power system.  

Q:    What if I have some braille information but none of the panel keys work?

A:    Your braille display hardware (PowerBraille 40 or Navigator) is probably 
      connected to the same port as another device.  For example, you may have 
      connected PowerBraille 40 to LPT1, the first parallel port, but you may 
      have another device using the LPT1 interrupt request (IRQ).  The IRQ for 
      LPT1 is IRQ7.  If you have TeleSensory's Vista VGA in its default mode, 
      it uses IRQ7, so this can cause a conflict.  



      The solution is to move one of the devices to another port.  Either move 
      the braille display hardware to another port or change the IRQ setting 
      for Vista or the other device.  Many such devices require that you make 
      both a hardware (usually a jumper) and a software (usually a command 
      line option) change.  

Q:    What if I can't get Grade 2 braille on my braille display?

A:    You must load SPView2 to get Grade 2 braille output.  SPView2 is 
      TeleSensory's on-line Grade 2 braille translator.  The Screen Power 
      installation program asks if you want to install SPView2.  If you 
      answered No, you cannot get Grade 2 braille.  If you then try to load 
      SPView manually, after you loaded Screen Power, SPView2 will load BUT 
      WILL NOT WORK.  

      SPView2 must be loaded BEFORE Screen Power.  The SPView2 command line 
      comes just before the SPB command line in the Screen Power batch file 
      (SP.BAT).  The installation program does this automatically.  

      If you upgraded a Navigator from Gateway to Screen Power Braille, you 
      must use SPView2 instead of the View2 program that came with your 
      Navigator.

      The solution to any of the above situations is to either re-install 
      Screen Power and select "Load Grade 2" or edit the SP.BAT file to load 
      SPView2 before SPB.  Note that the SP.BAT file is in both the root 
      directory and the Screen Power Braille directory.  

      It is also possible that you deleted the panel key hotkey that executes 
      the Screen Power function "Enable Grade 2 Braille."  In default mode, 
      this is the PowerBraille 40 convex & concave keys (LEFT and RIGHT 
      Execute on Navigator).  If so, you can select Grade 2 Braille Display 
      Options (in the Braille Display Options menu) and select Enable OR you 
      can re-assign the panel key hotkey in the Panel Keys Hotkeys menu.  
      Follow the instructions in Chapter 2 of the User Guide.  

Q:    What if I can't load an application with Screen Power running?

A:    You probably do not have enough memory to run both Screen Power and your 
      application.  

      Screen Power is designed to use about 120K of expanded or extended 
      memory or a 200K swap file on your hard drive, taking only about 50K of 
      conventional memory for Screen Power.  This frees up more conventional 
      memory for running other applications.  If you don't have the necessary 
      expanded, extended, or hard drive space, all 400K or so of Screen Power 
      will go into conventional memory.  



      Screen Power will first look at the memory type you specified during 
      installation.  This is identified with a command line option in the 
      SP.BAT file (/X for expanded memory, /T for extended memory, or /F for a 
      file on the hard drive).  If it does not find enough of that type of 
      memory, or if you specified a memory type which you don't have, Screen 
      Power automatically uses its default setting, which is swapping to a 
      disk file on your hard drive.  If you do not have enough room on the 
      hard drive (about 200K) for the swap file, Screen Power goes entirely 
      into conventional memory and uses about 400K.  This makes it unlikely 
      that you will have enough conventional memory to run other applications.  

      The solution is to make sure you have enough expanded memory, extended 
      memory, or hard drive space for the swap file.  
      Another possibility is that you have other TSRs (Terminate and Stay 
      Resident programs) or device drivers loaded which are also taking up 
      memory.  The application you are attempting to use may require more 
      conventional memory than is available.  

      The solution to this is to eliminate some of the device drivers which 
      may be unnecessary, or load them high (refer to your DOS manual for 
      instructions).  Check your application to see if it can load with less 
      memory.  If you are not going to use Grade 2 braille, you can remove 
      SPView2 and save 20K or so.  

Q:    What if my cursor routing buttons don't work?

A:    Some applications do not permit dynamic re-positioning of the cursor on 
      the screen.  These are usually low-level editors or programs that do not 
      provide full-screen access.  An example of this is DOS Edit.  







                                            Appendix A: Screen Power Utilities


Screen Power has several utilities to help you customize your system.  
Following is a description of each.


SPBREAD.COM

Screen Power has a text-reading utility program called SPBREAD.  You can use 
this program to read any ASCII text file.  It has special commands designed 
for reading text files using a refreshable braille display.  The SPBREAD.COM 
program was installed during the Screen Power program installation process.  
It is in your Screen Power directory.  

You can use SPBREAD to read all the Screen Power user documentation files.  
These files are named INSTALL.TXT, USERGDE.TXT, MENUREF.TXT, and CMMDSUM.TXT.  
The files on the Manual Disk are compressed until you install them, so you 
will not be able to use SPBREAD.COM to read the manual files without 
installing them.  

Unlike DOS's MORE and TYPE commands which do not give you much control while 
reading text files, the SPBREAD.COM program gives you many useful commands.  
It even has the capability to read files larger than the memory of your 
computer.  It will perform forward and backward searches through the entire 
document for any text string.  

To use SPBREAD.COM, type the word SPBREAD followed by a space followed by the 
name of the file.  In the following example, the file we want to read is 
called INSTALL.TXT (the name of the file that contains this document, the 
Installation Guide).  To read it, type:
 
      SPBREAD INSTALL.TXT, then press the ENTER key.

When loaded, the SPBREAD program immediately displays the first screen of 
information.  Line 25 (the last line on the screen) contains status 
information.  You can learn about the reading commands by pressing Function 
Key 1 (F1) to bring up the Help screen. These are the commands described on 
the SPBREAD.COM Help Screen:

      ENTER                         Continue to next page
      ESCape or F10                 Terminate
      HOME or T                     Restart from top of file
      END or B                      Skip to bottom of block
      PAGE DOWN or D                Scroll down one page
      PAGE UP or U                  Scroll up one page
      W                             Wrap long lines on/off
      7 or 8                        Strip or leave hi-bit
      P                             Printer on/off


      LEFT ARROW                    Scroll left 20 columns
      RIGHT ARROW                   Scroll right 20 columns
      UP ARROW                      Previous, up one line
      DOWN ARROW                    Next, down one line
      /text                         Find text
      A or F3                       Find text again



SPBCOLOR.EXE

Purpose: Forces Screen Power's menu system to use monochrome or color mode.

Format:  SPBCOLOR /vc
         or
         SPBCOLOR /vm

Remarks: This utility must be followed by either a /vc or /vm switch.  The "v" 
         refers to video; "c" is color mode; "m" is monochrome mode.  Only the 
         menu system display in the current working session is affected.  This 
         is a good way to force Screen Power's menu system to display in 
         monochrome mode without affecting any application programs.  

Notes:   You can also use the /vc or /vm switch as a command line option to 
         the SPB.EXE program file.  To do that, just add the switch to the 
         batch file that contains your SPB.EXE program file.  The file is 
         usually named SP.BAT.  If you start Screen Power in monochrome mode 
         and later want to switch to color mode, you should not re-run the 
         SPB.EXE program file.  Instead, use the SPBCOLOR utility.


SPBPORT.EXE

Purpose: Forces Screen Power to use a specific communication port on the 
         computer.

Format:  SPBPORT /C1 or /C2 or /P1 or /P2

Remarks: The program name must be followed by a /c1 or /c2 or /p1 or /p2 
         switch.  The "c" refers to the computer's serial ports; "p" refers to 
         the computer's parallel ports.  Only the current working session is 
         affected.  Use this utility if you have loaded the SPB program but 
         the braille display hardware is not powered on or not connected to 
         the computer.  This will force Screen Power to find the braille 
         display hardware after the SPB program has been loaded.  

Notes:   If you change the communication port you use for the braille display 
         hardware, you should not use this utility to make the change 
         permanent.  Instead change the batch file.  Change the SPB program 
         line in the file to reflect the new connection. 


         Although you can use SPBPORT if you change from one communication 
         port to another, this is not the use it was designed for.  It may not 
         always find the port.
