OpenLogger Getting Started Guide
Welcome to the getting started guide for the OpenLogger. This guide walks through getting the OpenLogger set up to start logging data, from installing all required software, to calibrating the device and updating its firmware. At the end of this guide, the Digilent Agent and Waveforms Live will be running and configured to work with an OpenLogger connected to the local computer. This whole process will take approximately 10 minutes.
Set Up the Digilent Agent
The Digilent Agent is a service that runs in the system tray on Windows, Mac, and Linux and enables WaveForms Live to communicate with Digilent hardware. The Digilent Agent makes it easy to update the OpenLogger's firmware, configure its WiFi, and calibrate its instruments.
Download and install the Digilent Agent using the installers found on the Digilent Agent'sResource Center.
Important
The OpenLogger is not compatible with versions of the Digilent Agent older than 1.2.0. If an old version of the Digilent Agent is installed, please uninstall it, then install the newer version.
More details on the Digilent Agent and how to install it can be found on itsResource Center
Launch WaveForms Live and Connect the OpenLogger
波形生活provides a browser-based instrumentation environment for managing devices and acquiring data. More information about WaveForms Live and how it interacts with the OpenLogger can be found on their Resource Centers (波形生活,OpenLogger).
1.
Launch the Digilent Agent. The Digilent Agent must be running to allow Waveforms Live to communicate with the OpenLogger.
2.
Connect the OpenLogger to the computer via with a microUSB cable.
Note:It may take the several seconds for the computer to recognize the device the first time it is connected. Subsequent connections will be established faster.
3.
Launch WaveForms Live by navigating towaveformslive.comon a web browser. Alternatively, right click the Digilent Agent in the system tray and clickLaunch WaveForms Live- this will navigate to waveformslive.com in the default web browser if internet access is available, or a locally hosted version of WaveForms Live otherwise.
4.
In WaveForms Live, at the top of the screen, click theADD A DEVICE按钮。
5.
Choose theAGENToption to connect WaveForms Live to the OpenLogger.
6.
Click the'plus'(+) button to add a new device via the Digilent Agent.
7.
Choose the suggested OpenLogger device that appears in the drop down box.
Update the OpenLogger's Firmware
Upon establishing a connection to the OpenLogger for the first time, WaveForms Live will check the device's firmware to see if needs to be updated. The firmware must be updated from the factory default before the OpenLogger can be used.
Note:After the first required update, described in this guide, an OpenLogger's firmware can be checked and updated through its Configuration Menu, found through the Device Manager in WaveForms Live.
1.
ClickUpdate Firmwareand follow the instructions to update the firmware on the OpenLogger.
2.
Review theCurrent Firmware Versionon the device and theLatest Firmware Versionavailable.
3.
Select the latestAvailable Firmware Version.
4.
At the bottom right corner of the screen, clickUpdateto load the new firmware onto the device. The firmware update will take about 10 seconds to complete.
5.
With the update complete, clickDone.
Calibrate the OpenLogger
Before being used for the first time, a new OpenLogger must first be calibrated. This process determines constants used to accurately calculate analog voltages for data points being logged, and stores these constants in non-volatile memory.
Note:After first-time calibration, described in this guide, a device can be recalibrated, if desired, through its Configuration Menu, found through the Device Manager in WaveForms Live.
1.
When the device is connected to WaveForms Live for the first time, a prompt to calibrate the OpenLogger will appear. ClickOK.
2.
Connect the provided 2×18 flywires to the OpenLogger with thenub side facing towards the centerof the OpenLogger.
3.
Connect the red wire on pin 6 (DC OUTPUT 1) to the solid orange wire on pin 35 (Analog Input 1). Take a look at theOpenLogger Pinoutin the Reference Manual for details on which wire corresponds to which OpenLogger pin.
4.
In WaveForms Live, click theBeginbutton to begin calibrating Analog Input 1.
5.
Wait for the calibration initialization to complete.
6.
Connect the solid blue pin 33 (Analog Input 2 to the same red wire previously used and click theNext按钮。
7.
After calibrating Analog Input 2, continue through the remaining 6 analog inputs (the pink, green, gray, purple, yellow, and brown wires) until calibration is complete. Once all analog inputs have been calibrated, click theDONE按钮。
8.
A final calibration complete screen will appear. Click theDONEbutton - see the image to the right.
9.
Click theDONEbutton at the bottom of the page to back out to the configuration screen.
10.
In the device configuration screen, click the back arrow at the top left of the page to return to the device selection screen.
