    ritaSn reacted to Julia Austin in Technical Support Bulletin 011 - SymphoniePLUS3 SD Card Formatting   
    Technical Support Bulletin 11 ? SymphoniePLUS3 SD Card Formatting 13 August 2012


    This bulletin applies to SymphoniePLUS3 data loggers with serial numbers below 494102284 and firmware version 34 or lower. These loggers shipped from NRG Systems before 1 August 2012. Any SymphoniePLUS3 logger shipped after that date has newer firmware installed that eliminates this SD card issue.

    Description of Issue

    NRG Systems has discovered a vulnerability in the SD card data storage of SymphoniePLUS3 data loggers. The problem is an addressing issue that causes the SD card to stop storing logged data. We have seen this condition develop after approximately 250 daily raw files are written to the SD card. In some cases, the Symphonie iPack?s programming can also become corrupted. This issue does NOT affect earlier Symphonie and SymphoniePLUS loggers which use an MMC memory card.


    NRG Systems has developed a proprietary format for SD memory cards used with SymphoniePLUS3 loggers that resolves this issue. SD cards that have been formatted using this structure will work with all Symphonie loggers and will prevent the issue with SymphoniePLUS3 loggers described above.
    NRG Systems factory formatted cards can be identified by the marking ?NRG FAT-A? on the card label. This will also show as the ?volume label? if inserted in a PC and viewed in Windows Explorer.

    A Windows application - SymphoniePLUS3CardFormatter.exe - has been released and is available as a free download by following this link: http://nrgapps.com/SDformatter.php

    All SD cards used in SymphoniePLUS3 loggers that are not marked ?NRG FAT-A? must be formatted using this program. Alternatively, NRG can provide newly formatted SD cards upon request free of charge.

    What you should do:

    1) Identify which of your sites have SymphoniePLUS3 data loggers.
    2) Check RWD file numbers from each site to estimate the number of days remaining before reaching 250. SymphoniePLUS3 creates daily files, and each RWD contains a file number counter in the 3 digits to the left of the .RWD file extension: SSSSYYYYMMDDXXX.RWD SSSS = site number; YYYY = year; MM = month; DD = day; XXX = file number
    3) Schedule a field visit to install a properly formatted SD card before it reaches file number 250. If it has already stopped logging, be prepared to reprogram the attached iPack (if present) with its IPK file. Feel free to contact us if you need assistance with this.

    We are sorry for any inconvenience this may cause you, and please contact NRG Technical Support if you have any questions: support@nrgsystems.com

    ritaSn reacted to Steve_Heidra in NRG #40 anemometers   
    I have just tested two uncalibrated #40 anemometers and a calibrated #40 anemometer in a wind tunnel under identical conditions.  I was really concerned about the results and tried to make contact with NRG with no response as yet.  I tested between 1 and 20 m/s.  Above 5 m/s the results showed reasonable agreement.  Below 5 m/s the new calibrated #40 show significant sticking.  Extrapolating the above 5m/s calibrated results below 5 m/s indicates the uncalibrated #40 anemometers (used for 8 months) showed no noticeable sticking down to 1 m/s, but rather overspeeded by more than 1 m/s.  When used in an MCP analysis for a low wind speed site these results are of a high concern.  COME ON NRG.  We need some answers.  I feel I might as well buy some cheaper product or go for a product which you can trust.

    ritaSn reacted to AppSupportDork in SymphoniePRO site files and encryption   
    I'm attempting to use the command line to process some encrypted .RLD files using SymphoniePRO Desktop. I've created a site file and saved the encryption password to it via the SymphoniePRO Desktop UI, and I've verified the encryption password has been saved, as I can import files without the prompt for the encryption password. This seems to demonstrate the site file retains the encryption password, but it doesn't work when processing via the command line. The context I'm using to process the files is:
    C:\RNRG\SymPro\> start /wait SymPRODesktop.exe /cmd convert /file <RLD filepath> /site <ndb filepath> And I keep receiving the error:
    Decryption failed: <RLD filepath> The documentation states that the /site switch uses scaling information from the site file, but nothing is mentioned about an encryption password. This is leading me to think the encryption password doesn't get retrieved from the site file when command line processing, and it might not be possible to process files in this way. Can anyone verify this, and if it indeed isn't possible to do, are there any plans to implement this in an upcoming release of SymphoniePRO Desktop?

    ritaSn reacted to pcorcoran in iPackGPS.rwd Files   
    From time to time we've heard of customers receiving 2 KB data files titled "iPackGPS.rwd" instead of the normal 14 KB files.
    When the files are opened, the following error pops up, and the file is empty:


    This is caused by a communication error between the logger and SD card, which results in the iPackGPS being unable to locate and send the correct file. Instead, it sends an empty placeholder file, which is the "iPackGPS.rwd" file. Although the placeholder file sent contains no data, the complete raw data file is still stored on the logger's SD card.

    To correct the miscommunication, install a new NRG FAT-A formatted SD card or reformat the existing SD card and reset the logger. We do NOT recommend using locally sourced SD cards!

    Option 1: Insert a new SD Card:
    Remove the existing SD from the logger, press the reset button (shown below), and then insert a new NRG FAT-A formatted SD card.
    Watch the logger screen as the SD card is "Initialized" and make sure it returns to the Home Screen without saying "Initialization Failed".  If the initialization fails, reformat the card (see instructions below) or throw the card away.
    To confirm that the SD card is working properly, press [Home 2. Status 2. Mem Card Status].
    The screen should read:
    Card Inserted
    ## Files Stored
    ### Days Left

    "Call Now":
    In order to verify that the new or reformatted SD card is working properly, perform a Call Now to send a data file. Please note that you will have to wait until just after the top of the hour for the logger to write a file to the SD card (this is done at the top of each hour).

    On the logger keypad, press [Home --> 3. Utilities --> 4. iPack --> 1. Call Now].

    Watch as the call goes through and then confirm with whoever receives the data that they got a file and it is readable.

    NOTE: If "Partial Files" are turned off on the iPackGPS, no data file will be sent. The iPack settings will need to be modified in order for a test call to be made and a file sent. The other option is to wait until the next scheduled call and then confirm that the files are being sent correctly.

    Option 2: Reformat the SymphoniePLUS3 SD card:
    1.    Navigate to www.renewablenrgsystems.com/technical-support/software and select "SymphoniePLUS3CardFormatter.zip" to download.

    2.    Extract ZIP file to any local folder (for example, C:\NRG\SymDR\).

    3.     Insert NRG SD card into SD card reader.

    4.    Launch Windows Explorer (Start -> Computer) and find the drive letter associated with the card. The card is often read by drive (E:)

    5.    Navigate to the directory where the zip file was extracted.

    6.    Launch by double clicking SymphoniePLUS3CardFormatter.exe.

    7.    Select the drive letter from the drop-down list in the tool that corresponds to the SD card (per step #2). Click the button labeled "Format SD Card" to start the process.

    8.    Press the ?Enter' key when prompted by the command line pop-up window that will appear.

    9.    Wait for the program to complete, look for the message indicating that the format completed successfully.  Then look at the SD card in Windows Explorer, where it should look like this:

    10.    Remove the SD card from the reader. It is now ready to be used in a SymphoniePLUS3 data logger.

    11.    Confirm that the SD card is working properly by pressing [Home --> 2. Status --> 2. Mem Card Status].
    12.    Perform a "Call Now" as described in the previous section to verify that the iPack is able to get the right file.


    If the format fails, try again. If it keeps failing, try doing a simple Windows format, and then try to format the card again with the SymphoniePLUS3 Formatter App. If card formatting continues to fail, try using an SD card reader instead of the computer's built-in SD card slot. If this does not work, or if an external card reader is not available, try running the program on a different computer.

    ritaSn reacted to johng in How do I interpret the SDR wind rose report?   
    See the example PDF above...
    The extension of each bar in the wind rose from ?inner
    circle? towards ?outer circle? represents the percentage of the time the wind
    blew from those various directions. 
    The outer circle percentage indicates
    the amount of relative uniformity of the wind direction.  For example, if
    there was a very strange site where the wind only blew from one direction all
    the time, and never from any other direction, there would be a single bar going
    out from 0 to 100%.  Most sites, however, have more scatter with wind
    directions distributed among numerous directions. 
    All of the bars
    extending out will of course add up to 100% of the time period that was
    measured.  The ?outer circle? value is intended to provide some context
    for the graph so that at a quick glance, you can tell that at the site below,
    almost 30% of the time, the wind direction was southwest, another 25% or so was
    north, and then the rest of the directions are distributed among the other
    directions to add up to the remaining 45%.

    ritaSn reacted to ltj in Update on #40C Sensor Shipments   
    For some time now we have been studying and checking NRG #40 anemometer tolerances and manufacturing processes in tremendous detail to understand what has been causing some of the sensors to intermittently underreport wind speed. 
     Recently we reported that a vibratory mode had been identified as the cause of the slow down. As a result of our analysis and testing, we have revised the specifications of certain materials and tightened the tolerances of certain dimensions of the sensor.  These improvements have eliminated the vibratory mode in test sensors in our laboratory. We have further validated these improvements in wind tunnel tests and in limited field tests. Final validation of these improvements must await the results of longer term field data which will take another 6 to eight weeks.
    We are confident, based upon the results of our laboratory testing, that these changes have a high potential to significantly reduce the probability that a sensor will degrade in the field. Therefore, we believe that it is appropriate to integrate these modifications into the NRG#40 immediately.  As of January 5, 2009, all sensors will ship with the improvements.

    ritaSn reacted to pcorcoran in Upgrading SymphoniePRO Logger & iPack Firmware   
    Version 1.2 and higher of the SymphoniePRO Desktop Application will detect when new firmware is available for SymphoniePRO Loggers and iPacks and notify the user that they are available. The following instructions show how to use the Desktop Application to upgrade the firmware. 
    Downloading Firmware Files:
    A flag in an orange box will appear to the left of the File menu on the top menu bar if there is new firmware available for SymphoniePRO Loggers and/or iPacks. Clicking the flag will open the 'SymphoniePRO Application Updates' window, which will list the latest firmware versions available.

    Click the Download button to download the firmware. The firmware will download into the Documents\Renewable NRG Systems\Firmware folder by default.
    [You can change the location that the firmware files are downloaded by clicking 'File' in the upper right hand corner of the application screen and choosing 'Settings'].
    *Note: If you are using an older version of SymphoniePRO Desktop Application (1.x.x.x.x), you will need to go to the RNRG Software/Firmware Downloads page http://www.renewablenrgsystems.com/services-support/documentation-and-downloads/software-downloads to download the latest firmware for the instruments you have. Place the downloaded firmware file in the Documents\Renewable NRG Systems\Firmware folder.
    Upgrading Logger Firmware with a USB or MetLink (remote) connection:
    Connect to the logger by establishing a MetLink connection or directly connecting the logger to the PC with a USB cord.
    Go to the Logger tab, and press the Upgrade Logger Firmware button in the Configuration section to open the Upgrade Logger Firmware window.

    Browse to wherever the latest firmware version is stored on your PC (by default it will be the 'Firmware' folder), select the firmware version, click 'Open' and then press 'Start Upgrade' to begin upgrading.

    Upgrading iPack Firmware with a USB or MetLink (remote) connection:
    To upgrade the iPack firmware, go to the iPack tab, and press the Upgrade iPack Firmware button in the Configuration section to open the Upgrade iPack Firmware window.

    Browse to wherever the latest firmware version is stored on your PC, select the firmware version, and click Start Upgrade to begin upgrading.

    Scheduling an automated firmware upgrade
    If you would like to schedule a remote firmware upgrade when you are not currently connected to a logger, this can be done in the Automation tab. Next to Logger (or iPack), check the Upgrade Logger (or iPack) Firmware box, browse to wherever the latest firmware version is stored on your PC, and open the firmware version. After selecting the firmware to upgrade, click Save to Site File at the top of the screen.

    The next time a MetLink connection is established (either Logger Initiated or Logger Listening), the firmware will be upgraded.
    Note: The only way to upgrade firmware remotely is through a MetLink connection. Therefore, it is highly recommended that you enable a MetLink Logger Initiated schedule, a MetLink Logger Listening Schedule, or both, when programming your SymphoniePRO logger.
