  1. The vibratory mode is not present in #40Cs shipped after January 1, 2009.  We are glad to replace any #40C sensors still covered by our standard 2-year warranty, installed or uninstalled, regardless of whether or not vibratory mode is present.  Please let us know how many sensors you have, their serial numbers, and whether or not they were installed, and we'll replace them at no charge.

    In most cases, we will ask that the anemometers are returned to NRG but if this is not possible, there are other options.

    Contact NRGTech Support (support@nrgsystems.com), and we will assist you with getting new #40Cs.

  2. Xxxxxxxxxxlog is incorrect for a "configuration patch"; what you paste into the Subject line and into the body of the email should be a 10 digit number only.  To that email message, you attach the patch file, which has a .ptc extension.
    More detailed instructions on patch files can be found here:

    When you do a "sensor patch", the patch file will have a format of xxxxxxxxxxlog.ptc; however, what you past into the Subject line and into the body of the email should only be a 10 digit number (no "log" and without a file extension).

  3. You can use a customized export from SDR to obtain logger internal temperature and voltage data.

    The first step is to make sure you've got a recent version of SDR (6.0 or above). 

    Please contact me, and I can send you a customized *.nef that provides internal temperature and logger voltage.

    Once you have the customized *.nef, here's what you do:

    Copy the *.nef files to the SYMDR folder (your version of SDR may in fact already have the withvt.nef in there).  On my computer, the path is C:/NRG/SYMDR, so if you've got a NRG folder, look in there.

    Start SDR as usual, and then go to Site, View Database, and click the Export button as usual.
    Choose the date range, and when the 'save as' dialogue window pops up, choose your customized *.nef.

  4.  Q: Is the Minimum wind speed for TIs of 4.5 m/s shown in SDR's "Editing Wind Rose" screen a default value?  If so, can it be changed?

     A:  Yes, 4.5 m/s is the default lower limit in SDR.  While it is possible to change the mimimum value, raising it could skew TI (turbulence intensity) calculations (i.e. if you only calculate TIs based on higher wind speeds, there may be higher average TI values, but in fewer directions because some of the data will be eliminated from the TI calculations). 

    Lowering the limit is not recommended because below 4.5 m/s is close to the threshold speed for wind turbines.  While the lower range of wind speeds is not of much interest for wind energy measurements, eliminating them could artificially inflate the overall TI averages, which are very important in choosing an appropriate wind turbine.

     


  5.  Stefano - are the anemometers you are comparing both #40C anemometers?  it sounds as though there may be a problem with the scale factors.  Can you send us some raw (*.rwd) files to review?  I'd like to try to duplicate the problem you are seeing and find the solution. Thanks!

  6.  The 9200-PLUS logger has no real-time output capabilities.  It is designed for logging time-series data at a remote site.  While instantaneous wind speed and direction can be viewed on the logger's display, there is no way to output this instantaneous data.

  7. Hi, Mike - the units of measure used in the reports are determined by what units of measure (in SDR's Site Information Editor window) were used to convert the raw data files when they were imported into the database.  If you prefer MPH, go into the Site Information Editor window to scroll through all your sensor channels, change the units of measure by using the "Load Defaults" button and choosing "#40 Anem MPH" from the drop-down menu, and then go to File and choose "Save Site".  Then re-import all of your data files - the data in the database will remain in m/s until you re-import.

     Let us know if you run into any problems and we'll do our best to help.

  8. Are you trying to connect with a serial cable or an AT MODEM cable?  The iPack must be connected using an AT MODEM cable.  However, it sounds like you should probably give us a call for assistance with the rest of this.  You will need to actually open up the iPack in order to change the SIM card.

     

    Please give us a call, and we'll be happy to help you.  Thanks!

    Ideally, a CDMA iPack using a Telus account would be intialized automatically using NRG's SDR software, and during the intialization process, the iPack's phone modem would obtain the PRL (PreferredRoaming List).  Unfortunately, many customers have not been able to do the standard intialization process successfully due a Telus cellular network issue.  Following is a workaround using the hidden Phone Diagnose window in SDR: 
     
    To use the Phone Diagnose window, you will need to do thefollowing:
    1. Open up SDR (Symphonie Data Retriever) on your PC.
    2. Type nrgphone on your keyboard (you do not need to enter this in any field - just type it into blank space).
    3. A dialog box will come up entitled Phone Diagnose - click on the CDMA tab.
    4. You will click the buttons on this screen from left to right starting with Get DIR, then Unlock SPC, Go Offline, Set DIR.
    5. When Set DIR is clicked, you will need to enter the 10 digit Verizon phone number is this field with no spaces. Click OK.
    6. Click Reset Mode, then Reset.
    *This method of phone initialization does not upload the PRL of the cellular provider.
     
    If this did not work, you will still receive one of thefollowing error messages:
    ? 072 - No carrier modem response.
    ? 075 - Access denied to internet server.
    ? 001 - Cannot make call.

    If you receive an error message, and everything is correctlysetup within the *.ipk file, contact NRG Tech Support for assistance.

  10. On August 29, 2009, Verizon Wireless will be shutting down their SMTP server smtp.vzwmail.net.  This will affect any iPacks using smtp.vzwmail.net as their SMTP Server Name.

    Sending the iPack a patch file with updated SMTP server settings prior to 8/29/09 will prevent an interruption in your iPack's communication.  Please contact NRG for assistance with sending a patch file, or check out the forum entries related to patch files for detailed instructions. 

    Wireless Innovation's Packet-Mail service is inexpensive and has been tested by NRG and found to work very well with iPacks. 

    For pricing information or to contact Wireless Innovation, send email to:

    sales@wi-ltd.net

  11. Unfortunately there is no way to test the GSM and ISP settings without the Symphonie logger.  However, you may send us a copy of your *.ipk file to review.  While we can't test your actual GSM connection, we can at least review the settings and see if there are any obvious problems.  You can email the *.ipk file to me at jma@nrgsystems.com.

    If you have multiple monitoring sites, it would be good to have a spare logger on hand for testing or available for quick replacement if one of your sites gets hit by lightning.  We sometimes have refurbished units available at discounted prices - please contact our sales department for more details.
