Overview

The NL241 provides Wi-Fi connectivity to dataloggers and peripheral devices over standard 802.11b/g/n networks. 

The NL241 is a wide-operating-temperature and low-power-consumption device, making it ideal for providing Wi-Fi client and access point functionality in demanding and remote applications. The wireless access point feature allows any Wi-Fi device to connect, including your PC, phone, tablet, or even another NL241 or NL240. It can be always on, cycled on an off under program control, or brought up with the touch of a button. Unlike the NL240, the NL241 is a true access point and does not rely on ad hoc networking.

This wireless network link interface is configurable to support a number of different types of connections including PakBus, TCP serial server and client, Modbus/TCP gateway, and Wi-Fi to CS I/O port bridging.

Benefits and Features

  • Wi-Fi access point for onsite connectivity
  • Mode button for easily turning access point on and off
  • Wi-Fi client allowing connectivity to existing networks
  • Low power consumption
  • IP communication with LoggerLink smartphone app and LoggerNet PC software

Compatibility

Bridging of Wi-Fi to CS I/O (also known as CS I/O IP or bridge mode) is only available over a CS I/O connection. Bridge mode only works with dataloggers that have a CS I/O port such as the CR800, CR1000, CR3000, CR6, and CR1000X.

The NL241 is compatible with the following: 

  • Device Configuration Utility (version 2.15 or greater)
  • CR800, CR1000, or CR3000 datalogger OS (version 31.08 or greater)
  • CR6 datalogger OS (version 06.08 or greater)
