performing a pause/resume or reset of the infinite average value in both the application and on 
iLC2ST. 
 

4. 

Per channel Short Term Average:

  Shows the short average of each channel on the graph.  A 

heavy vertical line shows where the target value on the iLC2ST is set.  Each channel’s reading 
is also shown in numerical form to the right of the graph, with the graph lines and the numerical 
value changing color to show the level of loudness. 

 

5. 

Status Bar:  

Three status boxes show more data that is collected from the unit.  The left box will 

display unit fault status.  Clicking on the box will display the history of faults captured by the 
Remote Dashboard software.  The center box shows Mix Monitor status of the selected tab.  
Clicking on the box will display the Mix Monitor history for that tab.  The right box displays the 
Remote Dashboard communication status.  Clicking on this box, while connected to an iLC2ST 
unit, will display additional information about that unit. 

 

 

Log Files 

   

The Remote Dashboard software’s main objective is to log your program audio loudness and have 
those measurements available for compliance verification. A new log file is created each hour and runs 
from x:00:00 to x:59:59. A new file will be created immediately if any data log options are changed. 
 
By default, measurement data log files are saved in the “logfiles” folder under the main Remote 
Dashboard application installation folder. A full day of logging each available data field once per second 
will consume approximately 27MB of storage space. Storage of files onto flash drives or other 

solid 

state storage 

devices is not recommended due to very frequent data writes the application makes and 

the “write endurance” of these devices. 
 
Logs are saved in Tab delimited format and can be imported into any database application that 
supports the importation of external data. Log files may also be imported into Microsoft Excel or 
Microsoft Access. The first line of each log file contains a column header that labels what data is 
contained within that column. 
 
 

Log File Import Example 

 

This brief procedure will demonstrate how to import the log file data into Microsoft Excel and render 
some simple graphs of the data. This procedure has only been verified to work in Microsoft Excel 
versions 2000, 2003 or 2007. 
 

1.

 

Open Microsoft Excel. In Excel 2007, click on the Data tab, and then click the Text button under the Get 
External Data group. In Excel 2000 or 2003, click on the Data menu, click Get External Data and then 
click Import Text File. 

2

 

The Import Text File box will appear. On the bottom of the window, click the Files of type drop down 
box and select All Files (*.*). Then, navigate to the location that the log files are stored in 
and select the appropriate log file. Double click on the file name or select the file and press the 

 

Import button.

The Text Import Wizard will start. Press the Finish button, as no values on these pages will 
need to be modified.
