兼容性

Wi-Fi ad hoc networking is provided for the purpose of networking between NL240 interfaces. Ad hoc networking is supported by iOS, allowing an iOS device to connect to an NL240 that has created a network. Wi-Fi ad hoc networking is not supported natively by Android OS and is difficult to support on Windows 7 and greater.

Software

Our Device Configuration Utility must be version 2.03 or higher.

Notes:
♣The CR300 connects to the NL240 using a 10873 serial cable that is not supplied with the CR300 or the NL240. The CR300-series dataloggers are not compatible with the bridge mode functionality in the NL240 interface.
* The data logger OS must be OS 25 or higher for bridge mode applications.
** It is possible to use an NL240 to connect to a mixed-array data logger (e.g., CR10, CR10X, CR23X, 21X, CR7) by using an SC32B between the data logger's CS I/O port and the NL240's RS-232 port.

常见问题解答

NL240: 15

展开全部收起全部

  1. Is the NL240 compatible with a WPA-Enterprise network?

    No, it is not.

  2. Does the NL240 come with a whip antenna?

    No. Antennas are ordered separately, allowing customers to choose the best antenna for their application and site.

  3. Does Campbell Scientific support IPv6 networking?

    Yes. We currently have, and continue to develop, a variety of products that are compatible with IPv6 networking. For example, the NL200/201 and NL240 can serve as IPv6 serial servers for our data loggers and communications peripherals. We anticipate IPv6 compatibility to be included in the CR800, CR850, CR1000, and CR3000 by mid-2014. 

  4. Using a CR800 or CR850 with a Wi-Fi adapter positioned near a Wi-Fi network hotspot, could a distant PC running LoggerNet collect the data logger data (or could the data logger send the data to the PC)?

    Yes. The NL240 wireless network link was designed for this purpose.

  5. What might cause a connection issue between a data logger and an NL240 in LoggerNet?

    If the NL240 is on a different network from the server running LoggerNet, either the station or LoggerNet needs to be able to initiate a connection to the other:

    • The NL240/data logger needs an IP address that is accessible to the LoggerNet computer

    OR

    • LoggerNet needs an IP address that is accessible to the NL240/data logger.
  6. Is there an Ethernet module available for the CR800 or CR850?

    The NL201 and NL240 are available options.

  7. In terms of a network link interface, what is "bridge mode"?

    The NL200-series of devices can be set to bridge the Ethernet or Wi-Fi interface and the CS I/O interface. All packets that come into the device via Ethernet or Wi-Fi will be transferred to the data logger over the CS I/O port. This enables the data logger to make all of its IP-related services available. Configuring an NL200-series device with bridge mode enabled is analogous to adding a native Ethernet or Wi-Fi port to the data logger. Bridge mode does not use PPP.

  8. Can communication be established between a computer and a CR3000, CR1000, CR800, or CR850 datalogger in a Wi-Fi network environment?
    Yes, using an NL240.
  9. How can two data loggers be connected to a single NL240 device?

    Connect one data logger to the RS-232 port (6784) and the other data logger to the CS I/O port (6783). To access a data logger on the RS-232 port, use the IP address xxx.xxx.xxx.xxx:6784. To access a data logger on the CS I/O port, use xxx.xxx.xxx.xxx:6783. For setup instructions and configuration assistance, refer to the NL240 instruction manual, use the LoggerNet Network Planner tool, or contact Campbell Scientific. 

  10. What are the powering options for the NL201 and NL240?

    The NL201 and NL240 are powered via the DC barrel connector and/or the CS I/O port. Sometimes, users who are using the network link
    interface as a serial terminal server, PakBus router, or Modbus gateway want to connect their devices via the CS I/O port while
    providing power only through the DC barrel connector and a 12 V source (such as a data logger SW12V output). In this scenario, a jumper
    inside the NL201 or NL240 can be removed, preventing the interfaces from always being powered by the CS I/O connections. For more
    information, refer to the instruction manual for the interface.
