Overview

The NL121 is the easiest and lowest-cost way to add an Ethernet interface connection to your CR1000 or CR3000. This small device, about the size of a deck of cards, simply plugs onto the data logger’s peripheral port. Through the NL121, you can access the Internet capabilities of your data logger, such as PakBus, Modbus, and DNP3 over TCP, as well as web, email, file transfer, and cloud-based application clients. You can collect from and control your data logger over any standard IP network—within your office or across the Internet.

Benefits and Features

  • The easiest way to add Ethernet to a CR1000 or CR3000
  • Provides a native Ethernet connection, allowing the data logger to communicate directly using a variety of Internet protocols
  • Integrated protection for surge and ESD
  • Data-logger-controlled power management for low-power operation
