Section 5
This section describes the features available on the Interrogator screen. DataLINE provides an interface to extract data from the DataCorder portion of the container refrigeration unit through the Interrogator utility. A set of features contained in the Interrogator utility allow the user to successfully download the recorded data and save the data into DCX files on the PC.
The Interrogator screen (Figure 5.1) is displayed when the user clicks on the Interrogator button in the Container Group Box on the Launch Pad.

The DataLINE application refreshes the screen in one of the following ways:
•AutoRefresh - Every 30 seconds the Interrogator screen automatically updates all data in the Recorder and Controller Group Boxes.
•Refresh Button - Provides the capability to manually trigger a refresh of the Interrogator screen.
•F9 - Provides a shortcut to manually trigger a refresh operation.
The Interrogator can perform the interrogation of the DataCorder using one of the following methods:
•By Date - Extract data between user specified dates.
•By Trip - Extract data for the user selected trip.
•Last 30 Days - Extract the last 30 days of data from the DataCorder.
•All Data - Extract all available records from the DataCorder.
The ViewData utility can be launched from the Interrogator screen (if successful connection is complete) by checking the box marked “View Data After Interrogation” before starting the interrogation.
Before starting the interrogation, it is important that a successful connection is established with the DataCorder. The status of connection can be determined as follows:
•If the connection is established only with the DataCorder, data is displayed in the fields of the Recorder Group Box.
•If the connection is established with both the Controller and the DataCorder, data is displayed in both the Controller Group Box and the Recorder Group Box.
•If the connection is not established with the DataCorder, all data in the fields in the Recorder Group Box will be displayed as “X's.” If the connection is not established, the Interrogator Group Box is disabled and the user is unable to interrogate.
•If the connection is not established with the Controller, all data in the fields in the Controller Group Box will be displayed as “X's.” Interrogation of the DataCorder can still proceed without a connection to the Controller.
If at any time during the display of the Interrogator screen the connection is not established or is lost, the user is alerted to the status of the connection.
After selecting the interrogation method and ensuring a successful connection has been made with the DataCorder, click on the “Start” button to begin interrogation.
Once interrogation has started and the data is being downloaded from the DataCorder to the file in the working directory, a progress bar displays the progress of the data download.
Interrogation can be stopped at any time during the download of data from the DataCorder. To suspend interrogation, click on the “Stop Interrogation” button.
After clicking the “Start” button to start downloading, the user is prompted to enter an interrogation file comment. The file comment is stored in the DCX file along with the interrogated data and is included in the reports generated using the ViewData utility.
The File Comment screen (Figure 5.2) is displayed when prompted to enter an interrogation file comment.

5.3.1Interrogation Results Summary Screen
The DataLINE application automatically converts the data from the DataCorder to a DCX file after download. After the download and conversion completes successfully, the Interrogation Results Summary screen (Figure 5.3) appears displaying the following:
•File name where data downloaded
•Number of records attempted for download
•Number of records successfully downloaded
•Number of records successfully converted to a DCX file
•Number of records not converted
