Our Modbus to Davis Vantage Pro2 Weather Station Gateway allows you to easily connect your PLC (Programmable Logic Controller), RTU (remote telemetry unit) or SCADA System to one of the following Davis weather stations:

The gateway plugs into the weather station's console using the Davis WeatherLink cable (Weather Link for Vantage Pro Serial) and appears on the Modbus network as a Modbus RTU slave. This allows your programmable controller to monitor and carry out actions based on wind speed, wind direction, temperature etc.
