Retrieve Data

Logger Pro allows the LabQuest, LabPro, Go! Motion, or WDSS to be used remotely. In remote operation the interface stores data on board, and later the interface is reconnected to the computer and data are retrieved. You can also use this feature if you have data on a Garmin GPS.

The Retrieve Data command is used to retrieve this remote data from a device to the computer. In all cases remote data are stored in new Data Sets, and are graphed on existing graphs if possible. If no existing graphs match the data units, then new graphs are created for the retrieved data.

For information on setting up an interface for remote data collection, see Remote Setup.

The initial steps of remote data retrieval vary slightly with the device and connection type:

Devices with a USB Connection - LabQuest, LabPro, GPS, or Go! Motion

  1. Connect the device to the computer by USB.
  2. Launch Logger Pro, if it is not already running.
  3. Logger Pro will detect the presence of remote data, and display the Remote Data Available dialog.
Devices with a Serial Connection - Windows Only
  1. Connect the device to the computer by serial cable.
  2. Logger Pro, if it is not already running.
  3. Choose Remote > Retrieve (device name) > Com port number used from the Experiment menu, where Com port number used is the particular serial port used to connect the device.
  4. Logger Pro will detect the presence of remote data, and display the Remote Data Available dialog.
WDSS with Wireless Connection
  1. Launch Logger Pro, if it is not already running.
  2. Choose Remote > Retrieve WDSS > WDSS name from the Experiment menu, where WDSS name is the name of the particular WDSS unit.
  3. Logger Pro will detect the presence of remote data, and display the Remote Data Available dialog.

You can choose any of the following options:

Cancel - Logger Pro will ignore the device and the data will remain on the device intact.
No - Select this option if you wish to proceed to live data collection. Important: If you are using a LabPro or Go! Motion and live readouts are enabled, the data will be overwritten. For other devices, live readouts or data collection will not affect the data on the device. Data will remain on the device and can be retrieved at a later time by choosing Remote > Retrieve (device name) from the Experiment menu.

If you choose Yes, the following window will appear:





Retrieve Remote Data into the Current File... The data will be retrieved into the current Logger Pro session. This option is useful when you have already prepared Logger Pro to display your data in a particular way.

Retrieve Remote Data into a Chosen File... Import the data into a previously customized and saved file. The remote data will be retrieved, and then you can choose an existing experiment file into which the data will be placed. This option is useful if you have prepared a file to display your data, but it is not currently open.

If you want to put the remote data onto two or more computers, check Make Data Available for Multiple Retrievals.



Remote Data for the WDSS

The WDSS will display an additional dialog box after clicking OK in the Retrieve Remote Data dialog, or by clicking the Manage Memory button in the WDSS dialog:

This dialog reports the memory status of the WDSS, including the number and type of data points stored in the device.

Here you can choose to retrieve the data and/or delete it from the WDSS, on a run-by-run basis. Unless you want to keep data on the WDSS to retrieve again later, you will probably want to delete the runs as you retrieve them. When you click OK, the indicated action will take place.



Remote Data for the GPS

When retrieving remote GPS data you will see an additional dialog box after clicking OK in the Retrieve Remote Data window.

 

For GPS data import you can choose to retrieve selected Waypoints, a single Track, or a Route. Select one Data Type, then select the particular data to retrieve. Click OK to retrieve the data and store it in a new data set in Logger Pro.

Regardless of the current GPS setting, locations are downloaded in decimal Latitude/Longitude format.
