1. Get started
Getting Started provides a cursory view of data acquisition and walks you through a procedure to
set up a simple system. You may not find it necessary to progress beyond Getting Started.
However, should you want to dig deeper into the complexity of the datalogger functions or
quickly look for details, extensive information is available in the online help or product manual.
This exercise will guide you through the following steps:
l Connecting the datalogger to a computer
l Attaching a sensor to the datalogger
l Creating a program for the datalogger to measure the sensor
l Making a simple measurement
l Storing measurement data on the datalogger
l Collecting data from the datalogger with a computer
l Viewing real-time and historical data with a computer
In addition to your datalogger, the following items are used in this exercise (many are shipped
with your datalogger and all are available on www.campbellsci.com). If you do not have all of
these items, you can provide suitable substitutes.
l Power supply (if not connecting via USB)
l Type-T Thermocouple, 4 to 5 inches long; one is shipped with the datalogger
l For a USBconnection:
o
Computer with a USBport
o
USB cable
l For an RS-232 connection:
o
Computer with a nine-pin RS-232 port
o
Serial cable
l Datalogger support software
Additional Campbell Scientific publications are available online at www.campbellsci.com.
Generally, if a particular feature of the datalogger requires a peripheral hardware device, more
information is available in the help or manual written for that device.
1. Get started 1
2. USB or RS-232
communications
Setting up a USB or RS-232 connection is a good way to begin communicating with your
datalogger. Because these connections do not require configuration (like an IPaddress), you
need only set up the communications between your computer and the datalogger. Use the
following instructions or watch a video.
Initial setup instruction follows. These settings can be revisited using the datalogger support
software Edit Datalogger Setup option .
1. Using datalogger support software, launch the EZSetup Wizard.
l
PC200W and PC400 users, click Add Datalogger .
l LoggerNet users, click Setup , click the View menu to ensure you are in the EZ(Sim-
plified) view, then click Add Datalogger.
2. Click Next.
3. Select your datalogger from the list, type a name for your datalogger (for example, a site or
project name), and click Next.
4. If prompted, select the Direct Connect connection type and click Next.
5. If this is the first time connecting this computer to a CR300 series via USB, click Install
USBDriver, select your datalogger, click Install, and follow the prompts to install the
USBdrivers.
6.
Plug the datalogger into your computer using a USBor RS-232 cable. The USB connection
supplies 5 V power as well as a communications link, which is adequate for setup, but a 12V
battery will be needed for field deployment. If using RS-232, external power must be
provided to the datalogger.
NOTE:
The Power LED on the datalogger indicates the program and power state. Because the
2. USB or RS-232 communications 2
datalogger ships with a program set to run on power-up, the Power LED flashes 3 times
every 10 seconds when powered over USB. When powered with a 12 V battery, it flashes
1 time every 10 seconds.
7. From the COM Port list, select the COMport used for your datalogger.
8. USB and RS-232 connections do not typically require a COM Port Communication Delay this allows time for the hardware devices to "wake up" and negotiate a communications
link. Accept the default value of 00 seconds and click Next.
9.
The baud rate and PakBus address must match the hardware settings for your datalogger.
The default PakBus address is 1. A USB connection does not require a baud rate selection.
RS-232 connections default to 115200 baud.
NOTE:
Unlike the RS-232 port on some other Campbell Scientific dataloggers that autobaud,
the CR300 RS-232 port does not. If the hardware and software settings for baud rate
and PakBus address do not match, you will not be able to connect.
10. Set an Extra Response Time if you have a difficult or marginal connection and you want
the datalogger support software to wait a certain amount of time before returning a communication failure error.
11. LoggerNet and PC400 users can set a Max Time On-Line to limit the amount of time the
datalogger remains connected. When the datalogger is contacted, communication with it
is terminated when this time limit is exceeded. A value of 0 in this field indicates that there
is no time limit for maintaining a connection to the datalogger.
12. Click Next.
13. By default, the datalogger does not use a security code or a PakBus encryption key. Therefore, the Security Code can be set to 0 and the PakBus Encryption Key can be left blank. If
either setting has been changed, enter the new code or key.
14. Click Next.
15. Review the Communication Setup Summary. If you need to make changes, click Previous to
return to a previous window and change the settings.
Setup is now complete, and the EZSetup Wizard allows to you click Finish or click Next to test
communications, set the datalogger clock, and send a program to the datalogger. See Testing
communications and completing EZ Setup (p. 4) for more information.
2. USB or RS-232 communications 3
3. Testing communications and
completing EZ Setup
1. Using datalogger support software EZSetup, access the Communication Test window. This
window is accessed during EZ Setup (see USB or RS-232 communications on page 2 for
more information). Alternatively, you can double-click a datalogger from the station list to
open the EZ Setup Wizard and access the Communication Test step from the left side of
the window.
2. Ensure the datalogger is connected to the computer, select Yes to test communications,
then click Next to initiate the test.
3. With a successful connection, the Datalogger Clock window displays the time for both the
datalogger and the computer.
l The Adjusted Server Date/Time displays the current reading of the clock for the com-
puter or server running your datalogger support software. If the Datalogger
Date/Time and Adjusted Server Date/Time don't match, you can set the datalogger
clock to the Adjusted Server Date/Time by clicking Set Datalogger Clock.
l Use the Time Zone Offset to specify a positive or negative offset to apply to the com-
puter time when setting the datalogger clock. This offset will allow you to set the
clock for a datalogger that needs to be set to a different time zone than the time
zone of the computer (or to accommodate for changes in daylight saving time).
4. Click Next.
5. The datalogger ships with a default QuickStart program. If the datalogger does not have a
program, you can choose to send one by clicking Select and Send Program. Click Next.
6. LoggerNet only - Watch a video or use the following instructions:
l The Datalogger Table Output Files window displays the data tables available to be
collected from the datalogger and the output file name. By default, all data tables set
up in the datalogger program will be included for collection. Make note of the Output File Name and location. Click Next.
l Check Scheduled Collection Enabled to have LoggerNet automatically collect data
from the datalogger according to a schedule. When the Base Date and Time are in
3. Testing communications and completing EZ Setup 4
the past, scheduled collection will begin on the first Collection Interval. Click Next
twice.
7. Click Finish.
3. Testing communications and completing EZ Setup 5
4. Connecting the datalogger to
a computer
Once you have configured your hardware connection (see USB or RS-232 communications on
page 2)(see Setting up Communications with the Datalogger for more information), your
datalogger and computer can communicate.
l
PC200W and PC400 users, select the datalogger from the list and click Connect .
l
LoggerNet users, select Main and click Connect on the LoggerNet toolbar, select the
datalogger from the Stations list, then Connect .

5. Creating a program in Short
Cut
Use the Short Cut software to generate a program for your datalogger. Short Cut is included with
your datalogger support software.
This section will guide you through programming a CR300 series datalogger to measure the
voltage of the datalogger power supply, the internal temperature of the datalogger, and a
thermocouple. With minor changes, these steps can apply to other measurements. Use the
following instructions or watch a video.
1. Using datalogger support software, launch Short Cut.
l
PC200W and PC400 users, click Short Cut .
l
LoggerNet users, click Program then Short Cut .
2. Click Create New Program.
3. Select CR300 Series datalogger and click Next.
NOTE:
The first time Short Cut is run, a prompt will ask for a noise rejection choice. Select 60 Hz
Noise Rejection for North America and areas using 60 Hz ac voltage. Select 50 Hz Noise
Rejection for most of the Eastern Hemisphere and areas that operate at 50 Hz.
A second prompt lists sensor support options. Campbell Scientific, Inc. (US) is usually the best
fit outside of Europe.
To change the noise rejection or sensor support option for future programs, use the Program
menu.
4. A list of Available Sensors and Devices and Selected Measurements Available for Output display. Battery voltage BattV and internal temperature PTemp_C are selected by default.
During operation, battery and temperature should be recorded at least daily to assist in
5. Creating a program in Short Cut 7
monitoring system status.
5. Use the Search feature or expand folders to locate your sensor or device. Double-click on a
sensor or measurement in the Available Sensors and Devices list to configure the device (if
needed) and add it to the Selected list. For the example program, expand the Sensors/Temperature folder and double-click Type T Thermocouple.
6. If the sensor or device requires configuration, a window displays with configuration
options. Click Help at the bottom of the window to learn more about any field or option.
For the example program, accept the default options:
l 1 Type TTCsensor
l Temp_C as the Temperature label, and set the units to Deg C
l PTemp_C as the Reference Temperature Measurement.
7. Click OK.
8. Click Wiring Diagram on the left side of the window to see how to wire the sensor to the
datalogger. With the power disconnected from the datalogger, insert the wires as directed
in the diagram. Ensure you clamp the terminal on the conductor, not the wire insulation.
Use the included flat-blade screwdriver to open/close the terminals.
9. Click Sensors on the left side of the window to return to the sensor selection window, then
click Next at the bottom of the window.
10. Type 1 in the How often should the datalogger measure its sensor(s)? box.
11. Use the Output Setup options to specify how often measurements are to be made and how
often outputs are to be stored. Note that multiple output intervals can be specified, one for
each output table (Table1 and Table2 tabs). For the example program, only one table is
needed. Click the Table2 tab and click Delete Table.
12. In the Table Name box, type OneMin to change the name of the table.
13. Change the Data Output Storage Interval to 1 minute.
14. Click Next.
15. Select the measurement from the Selected Measurements Available for Output list, then
click an output processing option to add the measurement to the Selected Measurements
for Output list. For the example program, select BattV and click the Average button to add
it to the Selected Measurements for Output list. Repeat this procedure for PTemp_C and
Temp_C.
5. Creating a program in Short Cut 8
16. Click Finish to compile the program. Replace the untitled.cr300 default name with MyTemperature.cr300 and click Save.
17. If LoggerNet or other datalogger support software is running on your computer, and the
datalogger is connected to the computer (see Connecting the datalogger to a computer on
page 6 for more information), you can choose to send the program. For the example program, click No.
NOTE:
A good practice is to always retrieve data from the datalogger before sending a program;
otherwise, data may be lost. See Collecting data (p. 13) for detailed instruction.
If your data acquisition requirements are simple, you can probably create and maintain a
datalogger program exclusively with Short Cut. If your data acquisition needs are more complex,
the files that Short Cut creates are a great source for programming code to start a new program
or add to an existing custom program using CRBasic. See the CRBasic Editor help for detailed
information on program structure, syntax, and each instruction available to the datalogger.
NOTE:
Once a Short Cut generated program has been edited with CRBasic Editor, it can no longer
be modified with Short Cut.
5. Creating a program in Short Cut 9
6. Sending a program to the
datalogger
The datalogger requires a CRBasic program to direct measurement, processing, control, and data
storage operations. The program file may use the extension .CR300 or .DLD.
A good practice is to always retrieve data from the datalogger before sending a program;
otherwise, data may be lost. To collect data using LoggerNet, connect to your datalogger and
click Collect Now . Some methods of sending a program give the option to retain data when
possible. Regardless of the program upload tool used, data will be erased when a new program is
sent if any change occurs to one or more data table structures in the following list:
l Data table name(s)
l Data output interval or offset
l Number of fields per record
Use the following instructions or watch a video.
1. Connect the datalogger to your computer (see Connecting the datalogger to a computer
on page 6 for more information).
2. Using your datalogger support software, click Send New or Send Program (located in the
Current Program section on the right side of the window).
3. Navigate to the the program, select it, and click Open. For the example program created in
Creating a program in Short Cut (p. 7), navigate to C:\Campbellsci\SCWin and select
MyTemperature.cr300.
l Number of bytes per field
l Field type, size, name, or position
l Number of records in table
4. Confirm that you would like to proceed and erase all data tables saved on the datalogger.
The program will send, compile, then display results.
After sending a program, it is a good idea to monitor the data to make sure sensors are taking
good measurements.
6. Sending a program to the datalogger 10
7. Working with data
By default, the datalogger includes three tables: Public, Status, and DataTableInfo. Each of these
tables only contains the most recent measurements and information.
l The Public table is configured by the datalogger program, and updated at the scan interval
set within the datalogger program, It shows measurement and calculation results as they
are made.
l The Status table includes information about the health of the datalogger and is updated
only when viewed.
l The DataTableInfo table reports statistics related to data tables. It also only updates when
viewed.
l User-defined data tables update at the schedule set within the program.
For information on collecting your data, see Collecting data (p. 13).
Use these instructions or follow a tutorial to monitor real-time data.
PC200W and PC400 users, click Connect , then Monitor Data. When this tab is first opened for
a datalogger, values from the Public table are displayed. To view data from other tables, click
Add ( ), select a table or field from the list, then drag it into a cell on the Monitor Data tab.
7. Working with data 11
LoggerNet users, select the Main category and Connect on the LoggerNet toolbar, select the
datalogger from the Stations list, then click Connect . Once connected, select a table to view
using the Table Monitor box.
7. Working with data 12
8. Collecting data
The datalogger writes to data tables based on intervals and conditions set in the CRBasic
program. After the program has been running for enough time to generate data records, data
may be collected by using datalogger support software. During data collection, data is copied to
the computer but still remains on the datalogger. Collections may be done manually, or
automatically through scheduled collections set in LoggerNet Setup. Use these instruction or
follow a tutorial.

LoggerNet users, select Main and Connect on the LoggerNet toolbar, select the data-
logger from the Stations list, then click Connect .
2.
Click Collect Now .
3. After the data is collected, the Data Collection Results window displays the tables collected
and where they are stored on the computer.
4. Select a data file, then View File to view the data. See Viewing historic data (p. 15) for more
information.
8.2 Collecting data using PC200W or PC400
1.
PC200W and PC400 users, click Connect .
2. Select the Collect Data tab.
3. Select an option for What to Collect. Either option creates a new file if one does not
already exist.
l New data from datalogger (Append to data files): Collects only the data in the selec-
ted tables stored since the last data collection and appends this data to the end of
the existing table files on the computer. This is the default, and most often used
option.
8. Collecting data 13
l All data from datalogger (Overwrite data files): Collects all of the data in the selected
tables and replaces the existing data files on the computer.
4.
By default, all tables set up in the datalogger program are selected for collection.
5. Click Start Data Collection.
6. After the data is collected, the Data Collection Results window displays the tables collected
and where they are stored on the computer.
7. Select a data file, then View File to view the data. See Viewing historic data (p. 15) for more
information.
