2 Installation

1.2 Introduction

There are two ways in which the Logic Engine software can be installed. The basic method, in which only the Logic Engine Tool set is available from within DESQview or the advanced method, in which the Logic Engine Tool set is available along with other applications that have been set up for use with DESQview. If you are not currently using DESQview, it is recommended that the basic method be used. Later, when the full power of DESQview is desired, the Logic Engine software can be reinstalled using the advanced method. If you are currently using DESQview or wish to use all the power of DESQview immediately, use the advanced method of installation. If you wish to use only the LE PI tool to develop your own tools, you will not need to install DESQview or the Logic Engine software at all. See section 2.6 for the procedure to install only the LE PI tool.

2.2 Before Installation

In order for the LE software tool set to run properly, your system should meet the following requirements:

2.3 Basic Installation

  1. Place the diskette labeled INSTALL in floppy drive A (other floppy drives can be used, simply use the appropriate drive letter instead of A)
  2. Type A: and press the RETURN key. From now on we indicate this with the line 
    A:
  3. Type TYPE README for any last minute instructions or modifications to the manual.
  4. Type INSTALL DV LE where: DV is the location where DESQview has been installed and LE is the location where the Logic Engine software tools are to be installed.
    Example:
    INSTALL C:\DV C:\LE

If an error occurs during the installation, an appropriate error message will be displayed. After an error, installation can be continued by correcting the problem and restarting the installation.

During installation, messages will be displayed indicating the progress of the installation. When installation is complete, a message will be displayed indicating so. At this point the Logic Engine software is ready to run as described in section 2.5.

2.4 Advanced Installation

The advanced installation procedure will install the following programs into the DESQview Open Window menu with the key stokes listed below:
Program Name Key Stroke
to Open Program
LE Panel PA
LE ASMB LE
ED PLD ED
TERM TR

If any of these key strokes interfere with a program that is already installed in DESQview, the advanced installation script (ADVANCE.BAT) can be edited to make the appropriate changes.

Performing the advanced installation procedure will create several new files in the DESQview directory and modify the file DESQVIEW.DVO. The old version of the file DESQVIEW.DVO will be stored in the file DESQVIEW.OLD.

The advanced installation procedure is as follows:

  1. Place the diskette labeled INSTALL in floppy drive A (other floppy drives can be used, simply use the appropriate drive letter instead of A)
  2. Follow the procedure for the basic installation (if this has not already been done)
  3. Type ADVANCE DV LE where DV is the location where DESQview has been installed and LE is the location where the Logic Engine software tools have been installed.

    Example: 

        ADVANCE C:\DV C:\LE

    During the advanced installation, messages will be displayed indicating the progress of the installation. If there is a conflict between one of the programs being installed and another program already installed, an error message will be displayed indicating that the program was not installed and installation will proceed with the next program. Once the advanced installation is complete, the programs will be available from the DESQview Open Window menu the next time DESQview is started.

    2.5 Starting Up the Logic Engine Software

    After installing the Logic Engine Software, you should do the following:
    1. Add LE to the PATH environmental variable in autoexec.bat
    2. Add the line set LE= LE to autoexec.bat
    3. Reboot
    Where: LE is the location of the installed Logic Engine software. If the Logic Engine software was installed using only the basic method, you will be using the Logic Engine Menu to start up the Logic Engine tools. To start the Logic Engine Menu type 
       LE
    Figure 2. Logic Engine Menu
    This will start up DESQview and bring up a menu as illustrated in Figure 1. DESQview should not be running before the Logic Engine Menu is started. The menu has five selections, one for each of the Logic Engine tools and one for DOS. To start up one of these programs, select it in one of four ways.
    (a) Type the two letters on the right side of the selection.
    Example: Type PA to select the LE Panel Tool.
    (b) Use the cursor keys to highlight the selection then press the Space Bar or Enter Key.
    (c) Use the mouse to highlight the selection then press the left mouse button.

    If the Logic Engine menu is ever obscured by other windows, it can be raised by moving the mouse to a spot on the screen which is not occupied by a window and pressing the left mouse button.

    If the Logic Engine software was installed using the advanced method, any of the Logic Engine tools can be started from the DESQview Open Window menu. See the DESQview manual for details about starting programs from the Open Window menu.

    2.6 Installing Only the LE PI Library

    If you desire to use only the LE PI library, it is possible to avoid installing DESQview and the Logic Engine software. To be able to link your own programs to the LE PI library you need two files off of the INSTALL diskette: 

        \bin\lelib.lib

    \include\lelib.h

    These can be copied to a convenient location on your hard disk. See 2.7 Installing the LE Board

    In order to operate the LE Board in a stand-alone fashion (no host PC), the power supply must be connected to the LE Board (see below) and plugged in and turned on. In order to operate the LE Board with the host PC, the parallel connector must also be connected to the host (see below.) Fig. 2 illustrates these connections.

    There are three connectors located on the right side of the LE Board (board oriented with switches face up and forward.) These connectors are, starting closest to the right most button and moving away:
    Parallel Connector: This is a male DB25 (25 pin) connector. It is connected to the host PC's parallel port (usually a female DB25 connector) via a male DB25/female DB25 parallel cable. This port is used for communication between the host PC and the LE Board. If any of the LE software is used to communicate with the LE Board, this connection must be made.
    Power Connector: This is a 5 conductor, unisex, color coded connector. It is connected to the power supply with an identical connector supplied with the power supply. This connection provides +5V, ground, -12V, +12V and 'power good' signals to the LE Board. The connection is made so that like colors of each connector match up. This connection must be made in order to use the LE Board.
    Serial Connector: This is a female DB9 connector. It is connected to the host PC's serial port (usually a male DB25 connector, sometimes a male DB9 connector) via a female DB9/male DB25(DB9) serial cable. This undedicated port is used to provide a serial port between the LE Board and the host PC. It is strictly for the designers use and is not used by any of the LE software.
