The Configuration function may be accessed up to three ways:

  1. Click the Configuration Tool icon if the default is set.

Screen Layout

The Configuration screen has the following areas:

Tree Area

The tree area is located on the left side of the screen. The names of each ECM on the data link are listed under the Available ECM(s) folder. Configuration Groups are listed under each ECM.

To view an individual group of parameters, click on one of the Configuration Groups. The selected Configuration Groups parameters will appear in the display area.

Display Area

The display area is located on the right side of the screen. To view a group of parameters, click on the plus [+] symbol to the left of a selected Configuration Group. The corresponding configuration parameters will be expanded.

Note: Information in both the Tree Area and Display area can be accessed using the arrow keys on the keyboard. Use the “Up” and “Down” arrows to move up and down the grid. Use the “Right” arrow to expand a selected Configuration Group. Use the “Left” arrow to collapse the group.

Note: The Configuration function has “mouse over” functionality. As the cursor hovers over the Configuration Group in either the tree or display area, the parameters within that Configuration Group are displayed in a pop up box.

The Configuration display area includes the following columns:

  • The Description column provides the name of the parameter set to configure. Icons that display in front of the parameter name give addition information about the parameter:
    • Require Factory Passwords
    • Locked through the Parameter Lockout function
    • Require Customer Passwords
  • The Value column displays the status of the current parameter
  • The Unit column displays the configuration parameter units.
  • The TT column displays the list of total tattletales. Tattletales represent the number of times a configuration value is changed. Note: For some products, Total Tattletales (TT) is not supported and will not be displayed.
