Revision History

Version 3.2.8 (Updated 28th Sep 2011)

- Added optional trace of logger Current Consumption to Harvest graphs.
- No longer allows apostrophe characters to be used in the logger Group and Tag.  No longer allows them to start with a space either - it is confusing.
- Added note for Windows 7 users if they cannot see any files when looking for logger data in C:\Program Files\Harvest\data\.  Under Windows 7 and Windows Vista, users may need to select the "Compatibility Files" option in Windows Explorer from the C:\Program Files\Harvest\ directory in order to find the data files within the "data" folder.
- Renamed "Plot Battery Voltage" to "Plot System Status" on graph right click menu for clarification.
- Added SDI-12 channel resolution display (for information purposes) on the Calibration options for an SDI-12 channel. This is to show the resolution that results after converting the floating point values from the sensor to scaled unsigned integers in order to store the values on the logger itself.
- Added In-Situ Aquatroll 100 and 200 Water Quality sensors to default SDI-12 sensor list.
- Added Ponsel SDI-12 Water Quality sensors to sensor list.  These include the OPTOD Optical Dissolved Oxygen sensor, Turbidity sensor, pH Redox Temperature and C4E Conductivity sensor.
- Added example file for FROG with OTT Pluvio Raingauge and FROG with IMP ultrasonic level sensor.
- Modified transparent SDI-12 command to Request Sensor ID to work for Aquatroll 100 and 200 sensors. It was considering the response to be invalid (a modem response) because it contained "AT".
- Fixed issue with multi column (multi parameter) CSV export where one channel was a periodic one and the other was non periodic (e.g. Rainfall).  The rainfall tips were shown as blank if they did not match the periodic interval timestamps.
- Includes firmware
  Hawk XT Mk 1 1.48, 1.58, 1.71, 2.03 and equivalents.
  Hawk XT Mk 2 102.03 and equivalents.
  Hawk RT 1.48 and equivalents.
  FROG RX 1.35 and equivalents.
- Fixed issue with Firmware Upgrades where if you did not have the Identify Device and Read and Reset Device tickboxes checked and the Firmware upgrade was cancelled, it was saying that the Firmware Upgrade had finished OK even though it hadn't.
- Added option to communicate directly with Fixed IP outstations without the need for a modem.  When entering the Dial Number you can now put in the IP address of the logger and the TCP port to connect on and it will try to connect and communicate to the logger through the internet instead of having to do a CSD call as before.  Harvest remembers both Fixed IP address and phone number for sites so they can be contacted by either method.  This requires Fixed IP firmware on the logger and the logger must be fitted with a Fixed IP SIM card.
- Added call duration and GPRS data volume statistics to XDQ files saved and to logger summary page.
- Added advanced option to show extra comms debug information.

Version 3.2.7

- Firmware version feature identification/description modified on tabbed configuration window to include Standard, DNP3, Fixed IP, GPRS.
- Fixed string buffer overflow possibility on saving XDQ file.
- Fixed xml to float array conversion issue.
- Added support for F1260 device.

Version 3.2.6

- Fixed occasional crash with drawing of rainfall alarms setpoints.
- Handles graphing and exporting of rainfall files where multiple tips have exactly the same timestamp.
- Removed FROG configuration option of setting SDI-12 current level via the Configure -> Set Current Level -> SDI-12 tab.   This was an error and should only apply to non SDI-12 level sensors.  The way to set the current level with a FROG and SDI-12 level sensor is to use the Configure All Parameters option.
- Added 5 minute GPRS checkin option on alarm condition (where the firmware supports it).

Version 3.2.5

- Fixed issue with configuration of FROG derived channels including adding an offset to a single channel. 

Version 3.2.4 (Updated 26th Apr 2011)

- Made clarifications to SDI-12 sensor wiring to include more terminology that may be used to
  describe the different sensor wires and how they should be wired to the FROG.
- Clearer warnings are given when exiting the configuration screen without
  applying any changes to the logger.  Renamed "Save" and "Load" buttons
  to "Save to Disk..." and "Load Config" respectively.
- Includes firmware
  Hawk XT Mk 1 1.48, 1.58, 1.71, 1.94 1.95 (Fixed IP) and DNP3 equivalents.
  Hawk XT Mk 2 1.96, DNP3 21.96 and Fixed IP 1.97.
  Hawk RT 1.46, DNP3 21.46 and Fixed IP 1.47.
  FROG 1.32 and DNP3 21.32 (supports D and E rev FROG board).  Fixed IP 1.33 and DNP3 Fixed IP 21.33.
- Added Ponsel Generic 5 Parameter SDI-12 sensor configuration.
- Added Alarm Count for logger on Summary screen and latest alarm details hover text.
- Fixed bug with Cursor position when you click on the graph to see details
  for a particular record.
- DNP3 firmware now supports DNP3 reporting of "offset" type of derived channels.
- Does not show GPRS checkin offset option for Daily Checkin option - this was misleading.
- Shows DNP3 Scaling Factor for Channel Parameter for Hawkeye 1, Hawkeye 2, FROG, Hawk XT and Hawk RT devices.
- Fixed issue with calibration parameter dialog for X and Y velocities on ChannelMaster SDI-12 configuration.
- Added plot of modem signal strength for XDQA plotting or for multiple XDQ files loaded together.
- Fixed issue where software would crash on rare occcasions if logger channel being read had a corrupt configuration.
- Fixed issue where loading a template file for the Isodaq digital interface would result in a version error message.
- Fixed issue on Isodaq SDI-12 Digital Interface configuration was not set up correctly having the mode '0' instead of the correct mode 'D'.

Version 3.2.2 (Updated 8th Feb 2011)

- Fixed CSV export issue in Pocket Harvest - strange characters were being appended to the end of the CSV file names.
- Does not give the choice of regular alarm check-ins on Hawk XT firmware version 1.58 as it does not support it.
- Fixed issue with drawing of XDQA alarms on graphs.  One alarm was sometimes not drawn or the wrong type of alarm was drawn.

- Patched version of Harvest 3.2.2 released on 8th Feb 2011 includes firmware

  Hawk XT 1.48, 1.58, 1.71, 1.84 and 1.85 (fixed IP) and DNP3 equivalents.
  Hawk RT 1.38 and DNP3 21.38.
  FROG 1.26, 1.27 (fixed IP) and DNP3 21.26 (supports D and E rev FROG board).  

  Hawk XT 21.84 and FROG 21.26 DNP3 supports some types of derived channels.

 The new firmware versions are the only changes - the Harvest executable remains unchanged from the preceding 3.2.2 Harvest release on 1st Feb 2011.

Version 3.1.9

- Added GPRS check-in options of 4, 6, 8 and 12 hours with 15 min updates on alarms.  No need for any firmware changes to support this.
- Prevented possible issue writing datanum to Hawkeye 2 devices.

Version 3.1.8

- Does not allow FROG to be configured for Isodaq 8 Way Digital Status SDI-12 sensor if firmware is 1.20 or less.
- Does not allow FROG to be configured for Daily Pulse Count Totals if firmware is 1.21 or less.
- Allows different storage intervals for different SDI-12 sensors as long as they are a factor of one another e.g. 5 minutes and 15 minutes.
- No longer uses ?! to wake up SDI-12 sensors in transparent mode when sending SDI-12 commands from Harvest e.g. Requesting measurements from SDI-12 sensor.
- Fixed issue in FROG configuration where 4-20mA sensor was enabled and SDI-12 channel was enabled but no parameters were selected and it incorrectly configured 2 channels.
- No longer displays Low Battery and Telemetry Disabled warnings if you are loading a saved XDQ template as by double clicking or loading it in Harvest.  These warnings only apply if there is real data in the XDQ file.
- Added support for 1072 FROG device.
- Added check-in offset option for GPRS check-in.  e.g.  Check-in every 12 hours with a 4 hour offset gives check-ins of approximately 0400 and 1600 instead of 0000 and 1200 with no offset.
- New feature allows user to select SDI-12 measurement command.  Before it would always use M! and you could not change that.  Now you can select M!, M0!, M1!, M2! etc.  This is of use for sensors that do not return the parameters that you want to record to the M! command.
- Check-in times and Timeswitch times are specified in UTC.  GPRS check-in offset is specified in terms of UTC+4 hours, for example.
- Fixed issue with multiple derived channels on the Hawk XT.

Version 3.1.7

- Added new feature to display full output filenames and links after exporting data to CSV/RLS file etc.
- Save as XDQA option.
- Added support for 8 way digital SDI-12 sensor in Multi-Parameter CSV.
- Added some system and memory diagnostics to About dialog.
- Added example Hawk RT data files for A42, A43, A44, A46, A52 and A61 application cards.  Added wiring details for Hawk RT A52 and A61 application cards.
- Channel Units in logger configuration can be edited on the Channel tab without having to go into Change Sensor/Calibration.
- SDI-12 units can be edited from table on SDI-12 tab without having to click on Calibration.
- COM port selection uses the previously selected port by default so it no longer has to scan the list of all available ports which can take quite some time on some machines.  COM port can still be changed but it is only done when the user specifically chooses to change it.
- Added a Generic 8 Channel SDI-12 Sensor to the list of SDI-12 sensors.  The range, units and parameter names can be modified to suit the sensor being used.

Version 3.1.6

 - Fixed intermittent issue setting SDI-12 level with some Hawk XT units.  When setting level, XT would not go back into SDI-12 transparent mode to retrieve the water depth from the sensor.  Extended comms activity to ensure XT always goes into this mode.

 - Fixed bug with exporting multi channel data immediately after it was read from the logger - only one channel was being exported.

Version 3.1.5

- Added Isodaq SDI-12 8 Way Digital Sensor
- New versions of firmware
- FROG DNP3 version 21.17 (Fixed bug with DNP3 Rainfall reporting)
- Hawk XT version 1.79 DNP3 version 21.79 (Fixed bug modem shutdown glitch)
- Fixed small memory leak with graph popup detail text.
- Windows 7 specific Harvest fixes.  View Data File now works - uses Temporary Internet folder to temporarily store XML file instead of c:\Program Files\Harvest\.  Data is automatically saved in c:\Program Files\Harvest\data\ by default but you have to either save it somewhere else or go to the folder in Windows Explorer and select Compatibility Files and it will then display the hidden XDQ data files in that folder.  Check For Updates does not work in Windows 7 because of tight security on the directory c:\Program Files\Harvest\.  Check for Updates link now takes you to a link on the Isodaq website on Windows 7.
- Added option Help -> Logger Manuals to provide an automatic web link to get the latest version of the data logger manuals for Hawk XT, Hawk RT and FROG.

Version 3.1.4  (Updated 28th April 2010)

- Added option for Daily Flow Totals with alarms on FROG and Hawk RT.
- Added Vietnam GPRS configuration settings.
- New versions of firmware with updated GSM and GPRS support for Telit GSM modem and Daily Flow Totals configuration option.
-  FROG version 1.16 (DNP3 version 21.16)
-  Hawk RT version 1.36 (DNP3 version 21.36)
-  Hawk XT version 1.78 (DNP3 version 21.78)

Version 3.1.3

- Fixed issue with pulse input and a derived flow channel on the Hawk XT and FROG.
- Fixed issue displaying two digital channels on Hawk RT with A45 card Ch 1 and Ch 3 digitals configured. 
- Fixed issue with GPRS check-in options Daily Checkin with more regular check-ins when in alarm condition. Loggers were checking in hourly etc all the time instead of only in alarm condition.

Version 3.1.2

- Added SDI-12 sensor management.  The user can now add, edit or remove SDI-12 from a User Defined SDI-12 Sensor list.  The full sensor list XdqSens.xml comes with the Harvest software installer and gets updated on every new installation or software update.  The library of User Defined SDI-12 Sensors
is maintained in the file UserSdi12Sensors.xml and it is not overwritten when a new version of the software is installed. 
- Lets you choose the SDI-12 level calibration type even if the Channel tag is not "Stage".  The SDI-12 channel calibration now has an option for all channels of "SDI-12 Normal" calibration or "SDI-12 Set Level" calibration.
- Added example data files for FROG with In-Situ RDO PRO and FROG with In-Situ Aqua Troll 200.
- Added YSI 600 OMS SDI-12 sensor.
- Fixed problem with number formatting on with numbers of 1000 or over. This
 was related to the new floating point formatting using the Windows locale.

Version 3.1.0

- Added "joins" on graph for XDQA file display.  Will show system status values when you hover over check-in date.
- Changed SDI-12 level setting.  Local comms no longer requires "last logged value" to be valid when setting SDI-12 level - now talks directly to sensor when setting SDI-12 level.  Setting SDI-12 level remotely by dialling site with a modem still uses "last logged value" method.
- Fixed bug where you could not set level to 0.0 with an SDI-12 sensor.
- Formats floating point numbers using Windows locale.  e.g. 1,6 or 1.6.

Version 3.0.9

- Removed possible bug with SDI-12 channel re-calibration.  When re-calibrating an SDI-12 channel on a sensor it was possible that a "Stage/Level" level reading could get corrupted.
- Added In-Situ RDO Pro DO SDI-12 sensor.
- Fixed bug with Setting level Below Datum with an SDI-12 sensor.  There were issues when changing from Above to Below datum.

Version 3.0.8  (Updated 4th February 2010)

- Added Campbell Scientific Temperature And Relative Humidity CS215 SDI-12 sensor
- Added OTT SE 200 SDI-12 shaft encoder sensor.
- No longer allows 10s or 30s logging for SDI-12 on Hawk XT or FROG.
- Contains Slovakian GPRS settings
- Now possible to specify the number of decimals for an SDI-12 channel.
- Fixed FROG bug where adding a second SDI-12 sensor would cause a problem.
- Fixed FROG bug with derived channel where you could not select the channel to be derived from.
- Fixed FROG and Hawk XT bug with derived channel where it was sometimes not shown correctly.
- Fixed bug with FROG configuration where if you selected SDI-12 address 2 it would appear as a Channel 2.
- Now only shows appropriate sensors for FROG Channel 1 (Digital) and Channel 2 (4-20mA).
- No longer shows FROG "Description" field which is not available on the FROG.
- No longer shows GPRS data usage field as Telit QC864 modem does not support it
- Fixed bug with DNP3 address changing when using "Set Telemetry Parameters" only (it would not change the values on logger even though you entered them).
- Comes with Hawk XT firmware 1.76 and 21.76, Hawk RT firmware 1.32, FROG firmware 1.12 and 21.12.  This provides support for Telit QC864 modem in addition to GR64 and GM47 GSM/GPRS modems.
- Plots HLC history
- Hawkeye 1 and 2 firmware no longer comes with the installation.

Version 3.0.6  (Updated 20th October 2009)

- Added Channel Number e.g. Ch 6 to SDI-12 data graph title.
- Fixed bug that meant that the SDI-12 address that you entered did not get used when you were sending a "Request Measurements" SDI-12 command.  It was always defaulting to address 0 no matter what was selected.
- Fixed issue where Hawk RT Rainfall example file could not be loaded.
- Added GSM Signal Test option to save graph of results to the Clipboard for putting in reports or saving to bitmap file.
- Updated list of SDI-12 sensors.
