Ethernet communications option

The CR310 offers a 10/100 Ethernet connection. Use Device Configuration Utility to enter the data logger IP Address, Subnet Mask, and IP Gateway address. After this, use the EZSetup Wizard to set up communications with the data logger. If you already have the data logger IP information, you can skip these steps and go directly to Setting up Ethernet communications between the data logger and computer. Watch a video at https://www.campbellsci.com/videos/datalogger-ethernet-configuration or use the following instructions.

Configuring data logger Ethernet settings

  1. Supply power to the data logger. If connecting via USB for the first time, you must first install USB drivers by using Device Configuration Utility (select your data logger, then on the main page, click Install USB Driver). Alternately, you can install the USB drivers using EZ Setup. A USB connection supplies 5 V power (as well as a communications link), which is adequate for setup, but a 12 V battery will be needed for field deployment.

  2. Connect an Ethernet cable to the 10/100 Ethernet port on the data logger. The yellow and green Ethernet port LEDs display activity approximately one minute after connecting. If you do not see activity, contact your network administrator. For more information, see Ethernet LEDs.

  3. Using data logger support software (ClosedLoggerNet Campbell Scientific's data logger support software for programming, communications, and data retrieval between data loggers and a computer., or ClosedPC400 Free entry-level data logger support software that supports a variety of communications options, manual data collection, and data monitoring displays. Short Cut and CRBasic Editor are included for creating data logger programs. PC400 does not support scheduled data collection or complex communications options such as phone-to-RF.), open 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. Also called DevConfig. .

  4. Select the CR300 Series data logger from the list

  5. Select the port assigned to the data logger from the Communication Port list. If connecting via Ethernet, select Use IP Connection.

  6. By default, this data logger does not use a PakBus encryption key; so, the PakBus Encryption Key box can be left blank. If this setting has been changed, enter the new code or key. See Data logger security for more information.

  1. Click Connect.

  2. On the Deployment tab, click the Ethernet subtab.

  3. The Ethernet Power setting allows you to reduce the power consumption of the data logger. If there is no Ethernet connection, the data logger will turn off its Ethernet interface for the time specified before turning it back on to check for a connection. Select Always On, 1 Minute, or Disable.

  4. Enter the IP Address, Subnet Mask, and IP Gateway. These values should be provided by your network administrator. A static IP address is recommended. If you are using DHCP, note the IP address assigned to the data logger on the right side of the window. When the IP Address is set to the default, 0.0.0.0, the information displayed on the right side of the window updates with the information obtained from the DHCP server. 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.

  5. Apply to save your changes.

Ethernet LEDs

When the data logger is powered, and Ethernet Power setting is not disabled, the 10/100 Ethernet LEDs will show the Ethernet activity:

  • Solid Yellow: Valid Ethernet link.
  • No Yellow: Invalid Ethernet link.
  • Flashing Yellow: Ethernet activity.
  • Solid Green: 100 Mbps link.
  • No Green: 10 Mbps link.
