5.0 WHAT'S NEW IN Version 5.34 Service Pack 3 of E-DAS
    Digi-Trend Central for Windows
_____________________________________________________________

5.1 Poll Manager and Poller Focus

Two flags were added to the [POLL] section of the EDAS.INI
file to allow the user to give the Poll Manager and/or
Poller window focus.  By setting the PMFOCUS to YES
(PMFOCUS=YES), the Poll Manager will have window focus
when it runs.  In the same manner, setting FOCUS to YES
(FOCUS=YES) will cause the Poller to have windows focus.
The default value for both flags is NO.


5.2 Data Editor Flags

A change to the data editors was made to allow the user to
assign a null value code to the "<" flag.  Previously, the 
"Set Flag Colorsand Null Value Codes" option did not work
properly for the "<" flag.  This problem has been fixed.
In order for the modifications to take effect, the user
first must delete the ESCFLAGS.TXT file located in the E-DAS
Program directory. After deleting the file, run the Matrix
Data Editor from the E-DAS Editors menu, and select the
"Set Flag Colors and Null Value Codes" option from the
editor's Flag menu. You can then assign a null code to the
"<" flag.

_____________________________________________________________

6.0 WHAT'S NEW IN Version 5.34 Service Pack 2 of E-DAS
    Digi-Trend Central for Windows
_____________________________________________________________

6.1 There are no significant changes to 5.34 Service Pack 2
of E-DAS Digi-Trend Central for Windows. 


_____________________________________________________________

7.0 WHAT'S NEW IN Version 5.34 Service Pack 1 of E-DAS
Digi-Trend Central for Windows
_____________________________________________________________

7.1 Purge Settings in EDAS.INI File

Additional settings were added under the [PURGE] heading of
the EDAS.INI file to allow the user to better manage disk
space used by various log files such as the Communication
Error Log, the Operator Message Log, etc.  The user may
also configure a minimum disk space limit, which will
generate an alarm if available disk space should become
lower than the limit.

These settings were previously defined in the file FILELIST.LIM


7.2 Hiding Configuration Menus in EDAS.INI File

Under the [SYSTEMTYPE] heading of the EDAS.INI file, the system
administrator may now hide configuration menus from users by
setting the SHOWCONFIG setting to NO (SHOWCONFIG=NO).  The
default setting is YES.  A typical network user of E-DAS
would have this setting to NO to prevent the network user
from altering any configuration data.


7.3 New Report

A Multi-Hourly Monthly Report has been added to the Report
Menu.


7.4 EDAS.INI Editor now allows edits on all settings

The EDAS.INI Editor available for administrators (logging
in with the "master" password) now supports all EDAS.INI
settings, allowing the administrator to edit the file from
the E-DAS Menu directly.


_____________________________________________________________

8.0  WHAT WAS NEW IN Version 5.34
_____________________________________________________________

8.1 Automatic Update of EDAS.INI File

As detailed in Section 4.0 of this README file the EDAS.INI file 
contains advanced options settings. Version 5.34 added some new 
fields to this file and will automatically update the existing 
EDAS.INI file during installation  to include these new fields, 
while retaining the user's previous settings for all other fields.


8.2 Matrix Data Editor

Users can now assign a different typeface for data flagged with
the less-than flag ("<"). This will allow the color of the 2nd 
priority flag to be viewed, while also indicating the presence of 
the less-than flag via the different type style.  The user can 
choose between, normal, bold, italic, and italic/bold type faces.  
Colors can no longer be assigned to the less-than flag.

8.3 On-Line Help

On-Line help is now available (WinHelp format) anywhere in the 
program. Pressing F1 or selecting Help|Help Topics will present 
on-line help, featuring Contents, Index, Find, and AnswerWizard 
(for asking questions in plain English).


_____________________________________________________________

9.0  MINIMUM REQUIREMENTS
____________________________________________________________

Each PC is different and larger monitoring networks may need more 
resources for optimum performance.  The following minimum PC 
hardware and operating system requirements are recommended for 
successful installation and operation of version 5.42 of the 
E-DAS software:

  300 MHZ Pentium processor

 128 MB RAM

  2 GB hard disk

  SVGA color monitor and graphics adapter 

  One serial port (A second port is necessary for remote 
  call-in to the PC.)

  One parallel port

  Printer (e.g., LaserJet, DeskJet)

		summary reports and monthly reports require 
		landscape printing.

  One internal CD-ROM drive
  
  Microsoft Windows 98/NT/2000/XP

10.0  EDAS.INI OVERVIEW
_____________________________________________________________

The E-DAS software uses a proprietary initialization 
file (.INI file).  It contains advanced options settings that 
usually do not need to be changed.  When an INI setting needs to 
be changed, the EDAS.INI file can be edited.  For example, a 
particular word processor can be specified to view reports.  The 
"VIEWERNAME" setting defaults to WordPad in Windows 95, 98,or NT.

The EDAS.INI file is located in the E-DAS program directory and it 
can be edited in two ways.  After logging on with the master 
password,  administrative personnel can edit the file via the 
"Admin" menu.  Operators without the master password can edit the 
EDAS.INI file directly in the E-DAS program directory. 

To make changes to the INI file after logging in with the master 
password, select Edit EDAS.INI file from the "Admin" menu.  You 
will see an INI File Editor.  To see the subcategories under each 
heading, double-click the heading or click the "+" sign to the 
left of the heading.  The subcategories will drop down.  Only the 
subcategories can be edited.  When you select a subcategory (e.g., 
"REPORTS | VIEWERNAME"), the current setting for that function 
will be displayed in the top-right text box labeled "Value".  The 
"Default" for that function will be displayed directly below the 
"Value".  To change the "Value", highlight it in the list and 
enter a new "Value" text box.  The "Default" cannot be changed.  
Click "OK" to save changes, or click "Cancel" to discard changes.  
You will return to the main menu.  

Operators without access to the "Admin" menu can edit the EDAS.INI
file directly in the E-DAS program directory via the 
Windows Explorer.  To make changes to the EDAS.INI file directly 
in the program directory, select "Programs | Windows Explorer" 
from the Windows 95, 98, or NT "Start" menu on the taskbar. In the 
left side of the Windows Explorer, double-click to open the 
Digi-Trend program directory.  In the right side of Windows 
Explorer, double-click the "EDAS.INI" (or "edas") icon within the 
program directory to open the EDAS.INI file in Notepad or WordPad.  
From the Notepad "Search" menu, select "Find" and enter the 
setting you need to change.  Click "Find Next".  (You can also scroll 
through the file and find the setting.)	 Edit the setting. From the 
Notepad "File" menu, select "Save," then "Exit."

Windows NT users need to modify the INI file if they get an error 
message ("Error displaying file") when they try to view reports.  NT 
users should open the EDAS.INI file as described above.  Find
"VIEWERNAME" under "REPORTS" and change the path to the viewing 
software from the default path of:
 
"VIEWERNAME=C:\PROGRA~1\ACCESSORIES\WORDPAD" 

to the path of your viewer, for example: 

"VIEWERNAME=C:\PROGRA~1\WINDOW~1\ACCESS~1\WORDPAD"
(Do not include quotation marks.)

If that setting does not work, or you are using Windows 2000, try: 

"VIEWERNAME=C:\PROGRAM FILES\WINDOWS NT\ ACCESSORIES\WORDPAD.EXE" 

	NOTE:	Every PC is different.  If neither configuration 
		works on your computer, select "Find | Files or 
		Folders" from your Windows "Start" menu and 
		enter "WORDPAD.EXE" to locate WordPad.  
		In the EDAS.INI file after "VIEWERNAME=," 
		enter the path to WordPad as it is listed in the 
		"In Folder" column of the "Find" screen.  If you 
		still get an error message, contact ESC 
		Windows technical support.
