Hosting a Wi-Fi network

By default, theCR300 series-WIFI is configured to host a Wi-Fi network. TheLoggerLinkmobile app for iOS and Android can be used to connect with aCR300 series -WIFI. Up to eight devices can connect to a network created by aCR300 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. 确保你的 CR300 -WIFI连接到天线和12 VDC吗power.

2. UsingDevice Configuration UtilitySoftware 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 theDeploymenttab, click theWi-Fisub-tab.

4. In theConfigurationlist, select theCreate a Networkoption.

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

6. ClickApply.

Connect your phone to the data logger over Wi-Fi

1. Open your phone settingsand connect to the Wi-Fi network hosted by the data logger. The default name is CR300followed by the serial number of the data logger.

2. Select theIP Portconnection type and clickNext.

3. In theInternet IP Addressfield, type192.168.67.1. This is the default data logger IP address created when the CR300 -WIFIcreates a network.

4. ClickNext.

   • Set anExtra Response Timeif 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 at00 seconds.

   • You can set aMax Time On-Lineto 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 of0in this field indicates that there is no time limit for maintaining a connection to the data logger.

6. ClickNext.

7. By default, the data logger does not use a security code or a PakBus encryption key. Therefore, theSecurity Codecan be set to0and thePakBus Encryption Keycan be left blank. If either setting has been changed, enter the new code or key. SeeData logger securityfor more information.

5. Next to theNetwork Name (SSID)box, clickBrowseto 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 thePasswordbox and add any additional security in theEnterprisesection of the window.

7. Enter theIP Address, Network Mask, andGateway. 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 to0.0.0.0. ClickApplyto save the configuration changes. Then reconnect. The IP information obtained through DHCP is updated and displayed in theStatussection of theWi-Fisubtab. Note, however, that this address is not static and may change. An IP address here of169.254.###.###means the data logger was not able to obtain an address from the DHCP server. Contact your network administrator for help.

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.
