1. Is there any way to set a variable in the data logger using LoggerNet to gain manual control over when data is collected by the data logger?

   A program snippet, such as the one below, would work for this purpose. The Boolean variable can be toggled from the Ports & Flags screen in LoggerNet (accessed via the Connect screen), through the Numeric Display (also accessed via the Connect screen), or under program control.

   public StoreDataFlag as boolean

   DataTable (ConditionalTable,StoreDataFlag,100)

             Sample (1,counter,Long)

   EndTable

   When storing data conditionally, be sure to allocate a specific number of records in the size parameter of the DataTable() instruction. For more information, see the Data Table Memory Allocation Tutorial.

2. 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.

3. Is there a way to set LoggerNet to download only the last x number of hours of data?

   On table-based data loggers, in the LoggerNet Setup screen, on the Data Files tab, there is the Collect at Most option that can be used to indicate how many records to collect. Based on how often data is stored, a calculation can be made to determine how many records represent x hours of data.

4. After installing an upgrade to the current version of LoggerNet, why does the Toolbar no longer show all the buttons?

   There is a difference between the Toolbar initialization files used in earlier 3.x versions of the software and more recent versions.

   To resolve this, close LoggerNet. Go to C:\Campbellsci\LoggerNet\sys\inifiles and delete the Toolbar.ini file. When LoggerNet is reopened, the Toolbar should display the default buttons.

5. Can backups from older versions of LoggerNet work on newer versions?

   Typically, a backup from an older version of LoggerNet will work on a newer version, but there will be issues trying to go from a newer version back to an older version.

6. How can data that has been transmitted from a data logger to LoggerNet then be transmitted to a webhost that displays the data graphically?

   The CSI Web Server enables the viewing of RTMC projects using a web browser. CSI Web Server allows configuring the web server, checking the status of the web server, and easily browsing to sites running on the web server. An RTMC project can be published to either a PC website or to an HTTP-enabled data logger. The CSI Web Server is included with RTMC Pro. It also can be purchased separately for use with the standard RTMC Development application that is bundled with LoggerNet, LoggerNet Admin, LoggerNetData, and RTDAQ.

7. Can the LoggerNet software used for a CR10X be used with a CR850 or CR800?

   LoggerNet version 3.3 and newer supports the CR10X, the CR800, and the CR850.
8. Can the CRBasic Editor be purchased without LoggerNet, or do they have to be purchased together?

   The CRBasic Editor is included with LoggerNet, PC400, and RTDAQ, which are software options available for purchase. The CRBasic Editor can also be purchased separately: www.campbellsci.com/crbasiceditor. 

   The CRBasic Editor has a number of features, such as syntax highlighting, context-sensitive help, a program precompiler, etc. However, the CRBasic Editor is not required to edit a data logger program. All data logger programs are simply text files that can be edited with any editor capable of handling plain text, such as Notepad, WordPad, vi, or Emacs. Caution should be used, however, editing a program in a text editor. Coding mistakes can make the data logger program run incorrectly or not at all.

9. Where is the data logger security code set up in LoggerNet?

   The security code is set up in the data logger Hardware tab of the LoggerNet Setup screen. Unlike the Device Configuration Utility, LoggerNet will not prompt for the security code on connection, so the setting has to be in the setup information.

10. What might cause trouble downloading data from a data logger 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.
