Virtual Ethernet over USB (RNDIS)

CR6 series dataloggers with OS version 7 or greater support ClosedRNDIS Remote Network Driver Interface Specification - a Microsoft protocol that provides a virtual Ethernet link via USB. (virtual Ethernet over USB). This allows the data logger to communicate via TCP/IP over USB. Watch a video at https://www.campbellsci.com/videos/ethernet-over-usb or use the following instructions.

  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). Alternatively, 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. NOTE:

    Ensure the data logger is connected directly to the computer USB port (not to a USB hub). We recommended always using the same USB port on your computer.

  1. Physically connect your data logger to your computer using a USB cable, then in 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. select your data logger.

  2. By default, the RNDIS address is 192.168.66. You can see the address by selecting IP as the Connection Type.

    If you wish to change the RNDIS address, click the Settings Editor tab >Advanced sub-tab > USB Virtual Ethernet Address (RNDIS) and enter the desired address. Note that 0 for the address defaults to 192.168.66.1.

  3. The Virtual Ethernet (RNDIS) address can be used to connect to the data logger using Device Configuration Utility or other computer software, or to view the data logger internal web page in a browser. To view the web page, open a browser and enter the IP address (for example, 192.168.66.1) into the address bar. For more information, see Web interface.

To secure your data logger from others who have access to your network, we recommend that you set security. For more information, see Data logger security.

NOTE:

Ethernet over USB (RNDIS) is considered a direct communications connection. Therefore, it is a trusted connection and Administrator privileges are automatically granted for all functionality.
