IoT Gateway

LM Gateway402-IoT data acquisition gateway, provides 2 RS-232 serial ports, 2 10/100 Mbps Ethernet ports, supports VGA, HDMI 2 groups of output, can be any synchronous or asynchronous dual display output. The OPCDA data acquisition driver is embedded in the gateway. As a Modbus RTU and Modbus TCP server, it provides external data. The gateway provides an http server and supports two common methods: GET and POST. Users can retrieve the gateway's real-time data and stored historical data through the http server interface.
