CR23X Micrologger Programming Steps

Downloading the LoggerNet Software & Connecting a NEW Datalogger

1. Download the LoggerNet software found on Campbell Scientific's website. (This software is not free to use and requires a license. You can contact Campbell Scientific for a quote on the software by taping “ordering info” on the top right hand side of the page. You will be prompted to fill out a form and submit your request for a quote.)

LoggerNet Software

2. Once you have access to LoggerNet software, click the desktop icon and the application will open.

3. Navigate to the Main tab on the top left-hand side, then choose “Setup” on the top right-hand side.

4. A setup screen will pop up and you will now choose the “Add” button on the top left-hand side. This will open the EZSetup wizard to guide you through adding the datalogger.

5. Click the “Next” button to continue throughout the wizard.

6. On the following page there is a list of common dataloggers on the left-hand side, you can navigate through the list to select the datalogger you have, in our case we will select the CR23XPB (which is the CR23X with the PakBus). After selecting the datalogger we will name the datalogger in the box labeled Datalogger Name, we will name ours “CR23XPB12Meter” and “CR23XPB4Meter” to differentiate from the two dataloggers we will have setup. Then, click “Next”.

7. The Connection Type page will display a list of modes of communication such as: Direct Connection, Phone Modem, IP Port, RF95/RF3XX, RF4XX (Non-PakBus), and MD9. We will chose “Direct Connection” for our method.

8. The COM Port Selection page will allow you to choose what port your datalogger is connected to. Ours is connected via USB Serial Port (COM4). You can also choose to have a communication delay that will allow the PC to load the necessary applications the normal delay is 2-4 seconds. We have ours set at 0.

9. Next is the Datalogger Settings page. Here we can select the baud rate that the datalogger will uses to communicate. The baud rate for the CR23X is 9600. You can also select the PakBus Address for your datalogger, we leave ours at the pre-selected value of 1. There are also options to change the Extra Response Time and Max Time On-Line, ours will be left at 0. (When pushing “Next” to advance a warning box opens and states that the PakBus Address is already being used. Just click continue and use 1 anyway.)

10. Datalogger Settings - Security is a page where you can set a code for security on your datalogger, a value of 0 means security will not be used. We will leave the code as 0.

11. Communication Setup Summary - is a chance to review the changes made to the setup of the datalogger.

12. Communication Test - Select yes to test the communication, or no to advance to the next step.

13. Datalogger Clock - Setting the datalogger clock is useful for when the displayed time and date doesn't match the date and time on the server. This step can be completed later if you aren't connected to the datalogger.

14. Datalogger Program - This screen allows you to upload an existing program. If you don't have an existing program you can skip this step by clicking “Next”. (Programming steps are going to be discussed later, so we are going to skip this step).

15. Datalogger Table Output Files - Skip this step until the program is completed.

16. Scheduled Collection - Check the box that enables scheduled collection. After you will choose how often you want the datalogger to collect data and where to output the data. We will choose 1 minute as our collection rate and the output file is: C:\Users\Dropbox\Surface\MetTrailer\data\CR23X_12M\raw\CR23X_12M.dat

17. Wizard Complete!

Programming a NEW Datalogger (CR23X)

1. Navigate on the LoggerNet software application and under Program, choose Short Cut. Here we can start the process of making a new program.

2. Once Short Cut opens, select “Create New Program”.

3. Select your datalogger from the list (CR23XTD/CR23XPB).

4. The next page will display the available sensors and devices for quick programming. For our program we decided to use generic differential voltage measurements. Under the Sensors folder, there is a folder labeled “Generic Measurements”. In the Generic Measurements folder you will see many options, we will choose “Differential Voltage”.

6. Under Voltage Measurement, you decide what to name the measurement and what units the measurement will be made in. We will chose to name ours after the channels they are wired to. Therefor, we have “CH01” measured in “mV” (a complete list of the channels, what the generic measurements are converted to and other important information is listed in the table above).

7. Range of Sensor Voltage will depend on the instruments you are deciding to connect to the datalogger (this information can be found in the manual for the instrument). Ours are all 0-5000mV, so 5000mV is selected.

8. Measurement Integration is already selected at “Reject 60 Hz Noise (16.667 ms)”, and this is the value it should stay on.

9. The Multiplier and Offset are used to convert the measurement to a different unit of measure and a calibration factor. For the multiplier a value of 0 has no effect on the measurement, a value of 0 will store 0 for the measurement taken. For the offset, a value of 0 has no effect on the measurement and is the standard value used.

Calculating the Multiplier and Offset Values

Most instruments will have the values for the Offset and Multiplier listed within their manuals. These values can also be calculated by using the range of the instrument and the range of the voltage. Here is an example:
