Gateway
The LG90E is the
Murata
family’s wireless Ethernet gateway for DNT90 900 MHz
Frequency Hopping Spread Spectrum (FHSS) based products, including the SN90xx
series sensor modems and the ZN-90M RS-485 serial modems. On the 900 MHz
side, the LG90E’s DNT90 radio provides robust wireless communications. On the
wired side, the LG90E provides a 10/100Base-T interface to connect to virtually any
Ethernet network. In between is the intelligence to allow seamless integration of
DNT90 based devices into network or Internet cloud based applications. The wide
array of Ethernet and Internet protocols supported reduces the effort to tie LG90E
networks into existing sensing and monitoring applications. The LG90E gateway
shares the same API as the other
Murata
gateway products, letting you pick the
wireless technology that best suits your requirements with only a minimum of
changes to your application.
