controller 2.7 full version
-----------------------------
This software replaces Software controller 2.7 full version.

Correct the following error(s) 
--------------------------------
Error corrected in controller 2.7 :
  - Peak settings can now be edited without error.
  - Detecting more than 30 peaks in a run doesn't cause anymore a software crash.
  - Sedex85 with firmware 2.1a is now detected correctly.
  - Sedex75 is detected more easily (no more frequent "timeout" message).
  - Printing a method a on computer without printer installed caused a bug.

Error corrected in controller 2.6 :
  - Even without the correct user rights, a user was able to create a method by using the 
    menus.
  - The software was waiting for "Ready signal" from detector instead of using the method
    pressure and temperature check parameters.
  - Sometimes, the record file had too much data : additionnal data from previous analysis
    could have been added at the end of file.
  - If 2 detectors were running at the same time the same method, recorded datas were
    incorrect.

Added functions in controller v2.6 :
  - the unused buttons on detector keyboard in manual mode are now greyed to avoid
    confusion.

Added functions in controller v2.5 :
  - autozero after gain change in a method is now an option.

Error corrected in controller v2.5 :
  - under some conditions, first offset of a method was not always applied.

Added functions in controller v2.4 :
  - some help buttons are added.
  - data files have more complete informations saved on analysis.
  - initialization time is improved after method load.

Error corrected in controller v2.4 :
  - if gas valve is closed, a method could not start. Corrected by opening gas valve at
    method load.
  - first offset of a method was not always applied
  - temperature order saved in file was always "0".

Added function in controller v2.3 :
  - Administrator functionality is enhanced to comply with 21CFR part 11 directive. 
  - "Password length" and "password lifetime" can be edited.

Error corrected in controller v2.2:
  - sometimes, the automatic autozero is not performed when changing automatically gain in
    a method run.
  - Add the following comfort function : when editing a method, if the method name is
    changed, the software requests before saving if the user want to overwrite really the
    method or create a new one with the new name.

Error corrected in controller v2.1.2:
  - When creating a method, writing a "," in pressure check and changing the value with +/-
    buttons crash the software.

Errors corrected in controller v2.1.1:
  - When running a method list, the second method (and the following methods) are running 
    without waiting trigger (button play or detector autozero).
  - Some minors errors are corrected (word spelling, colors).


Procedure :
-----------
- Download the executable install file and place in a temporary directory on your computer.
- run the install and follow instructions. User manual remains the same.

Note :
------
- IMPORTANT : upgrading your existing controller will change some parameters to comply 
  21CFRpart11.
  This change will cancel the ability to come back to the previous software version. It is
  recommended to make a copy of the actual software folder on harddrive in case of trouble.
- By using the patch version (only executable software) to upgrade an existing 2.x software,
  you have to replace the existing controller ".exe" file. Note that the windows shortcut
  won't be correct after this operation because the new software name is not exactly the 
  same. You have to create a new desktop shortcut for your comfort (see Microsoft 
  Windows help).
