NOTE:

A 12 VDC power source is necessary to power Wi-Fi functions of the CR300-WIFI.

NOTE:

The user is responsible for emissions if changing the antenna type or increasing the gain.

See also Communications specifications.

Hosting a Wi-Fi network

By default, the CR300 series-WIFI is configured to host a Wi-Fi network. The LoggerLink mobile app for iOS and Android can be used to connect with a CR300 series-WIFI. Up to eight devices can connect to a network created by a CR300 series. The setup follows the same steps shown in: CR6-WIFI Datalogger - Setting Up a Network .

Configure the data logger to host a Wi‑Fi network

Follow these instructions to check the data logger settings or reconfigure it.

  1. Ensure your CR300-WIFI is connected to an antenna and 12 VDC power.

  2. Using ClosedDevice Configuration Utility Software tool used to set up data loggers and peripherals, and to configure PakBus settings before those devices are deployed in the field and/or added to networks., connect to the data logger.

  3. On the Deployment tab, click the Wi-Fi sub-tab.

  4. In the Configuration list, select the Create a Network option.

  5. Optionally, set security on the network to prevent unauthorized access by typing a password in the Password box (recommended).

  6. Click Apply.

Connect your phone to the data logger over Wi-Fi

  1. Open your phone settings  and connect to the Wi-Fi network hosted by the data logger. The default name is CR300 followed by the serial number of the data logger.

  5. Save.

  6. All LoggerLink features are now available until the Wi-Fi connection times out with inactivity. See the in-app help for more information about LoggerLink.

Connect your computer to the data logger over Wi-Fi

  1. Open the Wi-Fi network settings on your computer.


    (Click image to expand/collapse display)

  1. Select the Wi-Fi-network hosted by the data logger. The default name is CR300 followed by the serial number of the data logger. In the previous image, the Wi-Fi network is CRxxx.

  2. If you set a password, select the Connect Using a Security Key option (instead of a PIN) and type the password you chose.

  3. Connect to this network.

Set up LoggerNet or PC400W

  1. Using Closeddata logger support software LoggerNet, RTDAQ, and PC400 - these Campbell Scientific software applications include at least the following functions: data logger communications, downloading programs, clock setting, and retrieval of measurement data., launch the EZSetup Wizard.

  1. Select the IP Port connection type and click Next.

  2. In the Internet IP Address field, type 192.168.67.1. This is the default data logger IP address created when the CR300-WIFI creates a network.

  3. Click Next.

  4. The ClosedPakBus ® A proprietary communications protocol developed by Campbell Scientific to facilitate communications between Campbell Scientific devices. Similar in concept to IP (Internet Protocol), PakBus is a packet-switched network protocol with routing capabilities. A registered trademark of Campbell Scientific, Inc. address must match the hardware settings for your data logger. The default PakBus address is 1.

    • Set an Extra Response Time if you want the data logger support software to wait a certain amount of time before returning a communication failure error. This can usually be left at 00 seconds.

    • You can set a Max Time On-Line to limit the amount of time the data logger remains connected. When the data logger 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 data logger.

  5. Click Next.

  6. By default, the data logger 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. See Data logger security for more information.

  7. Click Next.

  8. Review the Setup Summary. If you need to make changes, click Previous to return to a previous window and change the settings.

  9. Setup is now complete, and the EZSetup Wizard allows to you finish, or click Next to test communications, set the data logger clock, and send a program to the data logger. See Test the connection for more information.

Joining a Wi-Fi network

By default, the CR300-WIFI is configured to host a Wi-Fi network. Alternatively it can be set up to join an existing Wi-Fi network. Then a computer or mobile device on the same network can communicate with it.

Configure the data logger to join a Wi-Fi network

  1. Ensure your CR300-WIFI is connected to an antenna and 12 VDC power.

  2. Using ClosedDevice Configuration Utility Software tool used to set up data loggers and peripherals, and to configure PakBus settings before those devices are deployed in the field and/or added to networks., connect to the data logger.

  3. On the Deployment tab, click the Wi-Fi sub-tab.

  4. In the Configuration list, select the Join a Network option.

  5. Next to the Network Name (SSID) box, click Browse to search for and select a Wi-Fi network. To join a hidden network, manually enter its SSID.

  6. If the network is a secured network, you must enter the password in the Password box and add any additional security in the Enterprise section of the window.

  7. Enter the IP Address, Network Mask, and Gateway. These values should be provided by your network administrator. A static IP address is recommended.

    • Alternatively, you can use an IP address assigned to the data logger via DHCP. To do this, make sure the IP Address is set to 0.0.0.0. Click Apply to save the configuration changes. Then reconnect. The IP information obtained through DHCP is updated and displayed in the Status section of the Wi-Fi subtab. Note, however, that this address is not static and may change. An IP address here of 169.254.###.### means the data logger was not able to obtain an address from the DHCP server. Contact your network administrator for help.

  8. Click Apply.

Set up LoggerNet or PC400W

For each data logger you want to connect to network, you must follow the instruction in Wi-Fi communications option, using the IP address used to configure that data logger (step 7 in this instruction).

  2. Click Next.

  3. Select CR300 Series from the list, type a meaningful name for your data logger (for example, a site identifier or project name), and click Next.

  4. Select the IP Port connection type and click Next

  5. Use UDP Search... to find and Add the data logger IP address.

  6. Click Next.

  10. Review the Setup Summary. If you need to make changes, click Previous to return to a previous window and change the settings.

  11. Setup is now complete, and the EZSetup Wizard allows to you finish, or click Next to test communications, set the data logger clock, and send a program to the data logger. See Test the connection for more information.

Wi-Fi LED indicator

When the data logger is powered, the Wi-Fi LED will turn on according to Wi-Fi communication states:

  • Off: Insufficient power, Wi-Fi disabled, or data logger failed to join or create a network (periodic retries will occur).

  • Solid for 2 seconds: Attempting to join or create a network.

  • Flashing: Successfully joined or created a network. Flashes with network activity and once every four seconds when there is no activity.
