Benefits and Features

  • Low power consumption
  • Can be configured to bridge Ethernet and CS I/O communications
  • Has CS I/O, RS-232, and USB ports


Detailed Description

The 29354 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 29354 is an industrial Wi-Fi kit 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. The 29354 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
