The Name column will be populated with each variable name found in the Dimension Variable List of the DataGauge+ main screen. See "DataGauge+ Workspace" for more information.

3. Select the Device ID from the drop-down list for each variable. This defines the gauge device used to measure that dimension variable. These values come from the defined RS-232 modes and network connections defined in the Communication Configuration wizard.

4. As needed define the appropriate Channel for each variable from the drop-down list. Some devices have pre-configured channels that cannot be changed. The channel in those cases are automatically selected when the Device ID is set and are grayed out.

5. Click on the Apply these changes to all other cells with the same settings check box if appropriate. Otherwise, leave unchecked.

6. Click the Save button to save any changes made to the dialog. Click the OK button to save any changes made and return to the DataGauge+ main screen. Click the Cancel button to exit the dialog without saving any changes and return to the DataGauge+ main screen.

Note: When saving the Channel Selection settings, DataGauge+ will saved the data into an xml file named AssignedChannel.xml in the install path of the application.
