When you open the SensorConnect application you will find an icon in the top right corner of the window that looks like 3 horizontal lines:

When this icon is highlighted in orange that indicates that an update is available.  Click on the icon and select “update available”:

This will direct you to the location of the SensorConnect downloads page on the MicroStrain website.

Click on the download that corresponds to your system’s configuration (64-bit vs. 32-bit).  Once the download has completed double click the “SensorConnect_X.X.X.msi” file to run the installation.  Follow the on-screen prompts to perform the update.  Note:  SensorConnect will need to be closed in order to complete the installation.

When you re-open SensorConnect the icon in the top right corner or the window should no longer be highlighted in orange, indicating that you are running the latest version of the application.

The % bandwidth has to do with how many nodes/channels you can use at one time.  When setting up a Synchronized Sampling network, SensorConnect will interrogate each node and assign transmission slots for them to send data to the base station.  This is designed to keep the nodes from broadcasting at the same time and causing data loss.  The more channels, and higher sample rate of a node will require more transmission slots, thus higher % of available bandwidth used.

Excel displays our time stamp incorrectly.  If you were to open the data file in Notepad you would see the correct time format. 

To correct the data in Excel, Highlight all of column A, right click on the highlighted region and select Format Cells.  Under the Number tab select Custom, Scroll to the bottom of the list that appears and select “m/d/yyyy h:mm”.  You will need to add “:ss.000” to the end of this, so it looks like this “m/d/yyyy h:mm:ss.000” .  Setting the cells to this will give you the highest resolution that Excel can show.

We use Universal Coordinated Time (UTC) to collect data on all of our devices.  There is no provision to set the time to a local time zone. 

The IEPE-Link™ -LXRS® accepts inputs from most IEPE sensors using the industry standard 10-32 mini-coaxial connector and 2.3 mA constant current excitation.
