Identifying Software Versions

Because we are constantly striving to improve our products, it is important to keep track of which version of each product you have.  This is especially true when you are requesting technical support or looking to upgrade to the latest revision.  The latest release version for each DEI end-user software package is shown below:

ExpeDat
1.15B
SyncDat
1.2J
Tunnel
1.0H

Packages versus Components

Each MTP/IP application consists of many components.  These may include multiple executables, installers, documentation, and sample configuration files.  The overall collection of these things is called a "package".  Whenever any component changes, the package version is updated.  As a result, the version number of a package is often different from the version numbers of the individual components.

Package versions take the form of "9.9Z".  That is, two numbers and a letter.

Component versions take the form of "9.9.9".  That is, three numbers.

Package versions are important when you are downloading an application for installation because they help identify whether you have the latest download.  But when you are requesting technical support, it is the component version that is necessary.  This is because, over time, components from different packages may become mixed and it is vital to know exactly which component is involved.

Finding Component Versions

All DEI software will display its version number when you click the "Options" or "Help" button, or when you add " ‑v " to the command line.  For example:

prompt# servedat -v
(C)2013 Data Expedition, Inc.(R) US Pat. 7158479,7313627,7404003,7630315,8014289
servedat - 1.15.0 August 2013 - DEI, DOC-1.15.0 MTP-osx-3.15.11 853
00000001: ExpeDat-1.15A Data Expedition Inc., DEI Main Server

The version output contains many important pieces of information, some of which describe the software and some of which describe the person or company who purchased the software.

 Component Version 
The name of the software component and its version number.
 Build Code 
A serial number indicating when the software was produced.
 Customer ID 
The customer identification number for this license.
 Package Version 
The name and release version of the application package.
 License Name 
A description of the person or company licensing the software.  Customers may specify their own description at the time of purchase.
 Label 
A description of an individual component license or configuration.  Customers may specify a label for each server, typically short descriptive text which may be displayed to client users.  For trial software, the label usually shows the expiration date.

Server software will also display its full component identification as part of its diagnostic output each time it is started.  This output may be displayed on the console or recorded in a log file.  For example:

prompt# servedat
V 20130904 08:56:20.784 servedat 1.15.0 "August 2013" DEI [2017] (8080)
C 20130904 08:56:20.785 (C)2013 Data Expedition, Inc.(R) US Pat. 7158479,7313627,7404003,7630315,8014289
C 20130904 08:56:20.785 servedat - 1.15.0 August 2013 - DEI, DOC-1.15.0 MTP-osx-3.15.11 853
C 20130904 08:56:20.785 00000001: ExpeDat-1.15A Data Expedition Inc., DEI Main Server

Whenever you request technical support, please copy all lines of version information.

Production versus Trial

Most distribution package names end with either 'P' or 'T' to indicate whether they are perpetually licensed or time limited.  These are often referred to as "Production" and "Trial" packages, respectively.

expedat-win32-1.15A-P.zip

Software contained in "P" packages is perpetually licensed and will run continuously, but may require a license code.

expedat-win32-1.15A-T.zip

Software contained in "T" packages will only run for a limited time period, but usually does not require a license code.
