1. Why might the numeric and graph displays (accessed from the LoggerNet Connect screen) no longer update?

   If communication is interrupted or intermittent, LoggerNet may stop updating the Table Monitor, Numeric Display, and Graphs. When this occurs, a button on the display that is normally titled Stop (to stop the update) changes to Start, and the button must be pressed to resume the update. Also, check the update interval on the display, as it may be set to a higher value than expected.

2. How can a program be removed from a datalogger using LoggerNet?

   The Retrieve button, used to retrieve a program from a datalogger, is found on the LoggerNet Connect screen. Note that some dataloggers, such as the CR200X-series, do not store the program in a retrievable format, and the Retrieve button will be disabled.

   There is also a File Retrieval tab in LoggerNet on the Setup screen that can be used to retrieve files stored on the datalogger.

3. Would there be any major problems with moving a datalogger to another communications path while someone is using the LoggerNet software?

   As long as the same device is being moved from one communications route to another, all data collection pointers, filenames, etc., will be maintained with that datalogger as it is moved.

4. How can LoggerNet be used to edit the user drive size in the datalogger settings?

   Follow these steps:

   1. Connect to the datalogger using the LoggerNet Connect screen.
   2. Find the datalogger in the Stations list, and right-click it.
   3. From the menu that is displayed, choose the Settings Editor.
5. What might cause Windows to display a "Blue Screen of Death" when LoggerNet is running?

   Typically, blue screens are the result of bad device drivers. The Internet can be very helpful in tracking down the cause of blue screens. Copy down the codes displayed. Search the Internet for “blue screen” and the code to see what device is causing the crash. Often, an updated device driver will resolve the issue.

6. How long does it take to install LoggerNet?

   The LoggerNet application is distributed on CD media and can be installed in minutes.

7. Can LoggerNet perform scheduled data collection on two dataloggers at the same time?

   Yes, but only if the communications links to the dataloggers allow simultaneous communication. For example, two mixed-array dataloggers can be contacted simultaneously using two different COM ports; however, if they are accessed via the same COM port, LoggerNet can connect to only one at a time.

8. Is there a possibility to auto-update the graphs in View Pro or other functions inside LoggerNet 4 without pushing the Refresh button in View Pro?

   View Pro is meant to be a file viewer, so there is no automatic update capability.

   To view graphs in real time, there are graphs that can be launched from the numeric monitor. For fully customizable displays, RTMC can be used. RTMC uses the LoggerNet server for its data source, but RTMC Pro (purchased separately from LoggerNet 4) can also use a DAT file.

9. What might cause trouble downloading data from a datalogger using LoggerNet with a USB-to-serial cable?

   First, make sure the most recent version of LoggerNet is being used. (Improvements were made between versions 4.0 and 4.1 that resolved some issues with LoggerNet and some USB-to-serial cable drivers.) Next, ensure that the most recent drivers from the cable manufacturer are being used. Often, newer drivers are developed for devices after they are released, and the software shipped with those devices is not updated. The drivers can be downloaded from the manufacturer's website.

10. How can data during a certain duration be erased without erasing the configuration and the program?

    There is no mechanism to selectively erase data from the datalogger for a given date range. However, the data tables in the datalogger can be reset, which effectively erases the data.

    Note: Following these steps will cause the loss of all data:

    1. In the LoggerNet Connect screen, click the Station Status button.
    2. When the dialog box opens, select the Table Fill Times tab, which shows the data tables in the datalogger and their sizes.
    3. Either select individual tables, or select the Select All checkbox.
    4. Click the Reset Tables button. This will erase all data in the tables.
