Das NL240 ist ein Wi-Fi Netzwerk interface, dass eine drahtlose Verbindung zu einem Logger oder einem Peripheriegerät ermöglicht. Es unterstützt auch kompliziertere Netzwerk-Funktionen, vor allem wenn es in einem PakBus-Netzwerk eingesetzt wird. Mit dem NL240 können zum Beispiel mehrere PakBus-Clients zur selben Zeit mit einem Logger verbunden werden.Lesen Sie mehr

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.
Our Device Configuration Utility must be version 2.03 or higher.
♣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.
Current NL240 firmware. Requires the Device Configuration Utility and a USB micro cable.
Note: When updating to OS 10.03 from OS 6 or previous, settings will be reinitialized to factory defaults. When updating to OS 10.03 from OS 7, settings will be retained.

No. Antennas are ordered separately, allowing customers to choose the best antenna for their application and site.
No, it is not.
Yes. The NL240 wireless network link was designed for this purpose.
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.
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 NL201 and NL240 are available options.
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.
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 datalogger 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.
It depends on the application, funds available for new hardware, and the quantity of data that will be collected. Viable options include the NL240, RF4xx spread-spectrum-series radios, RF32x UHF/VHF radios, and cellular modems.
