Overview

The NL240 is a wireless networking peripheral that provides Wi-Fi connectivity to our dataloggers and peripheral devices over standard 802.11b/g/n networks. It is a low-power device that offers unique and powerful PakBus networking capabilities, but it is easy to configure. The NL240 provides direct access to all the IP capabilities of the CR800, CR1000, and CR3000 dataloggers.

Detailed Description

The NL240 can take advantage of the thousands of Wi-Fi hotspots available in cafés, universities, hotels, and airports. Wi-Fi also provides encryption to protect traffic and uses a global set of standards so the same device can be used internationally.

The NL240 is an industrial device that goes beyond the typical Wi-Fi serial device server. It supports Wi-Fi communication with an iOS or Android device when used with our LoggerLink apps. By providing direct access to all the IP capabilities of the CR800, CR1000, and CR3000 dataloggers, the NL240 provides:

  • M2M communication of data and events
  • PakBus communication over TCP/IP for remote configuration, control, and data collection
  • HTTP and FTP for posting, retrieving, and local hosting of data
  • Email client for data and control messaging
  • ModBus TCP/IP, DNP3, and NTCIP ESS industrial protocol support

Compatibility

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.
