Unmanned weather stations play an essential role in the effort to analyze and predict the world? ever-changing weather patterns. The unmanned stations collect and store large amounts of weather data and then download the data at regular intervals to a backend host for analysis and long-term storage. MOXA Ethernet I/O modules can be connected to UC-7420 via RS-485 to take care of data acquisition from the sensors at the weather station.

For this application, UC-7420 can be programmed to handle protocol conversion before transmitting the weather data back to the central weather station. In addition, UC-7420 can be used for preliminary data processing before the data is downloaded to the central computer. One of UC-7420's serial ports can also be connected to a V.90 or GPRS modem for PPP connections, and a PCMCIA port is available for installing a wireless LAN card for 802.11b/g networks.
