CIAP314R-1A2-485 is a device that can realize data communication between RS485 and Ethernet/Wi-Fi. The device supports Modbus RTU/TCP protocol conversion, through which the field serial port device can communicate with the remote SCADA system.

It integrates rich network protocols such as MQTT, TCP, UDP, SSL, etc., supports multiple networking modes, and is suitable for various scenarios. SSL encryption can protect the secure transmission of customers’ data and avoid the risk of data leakage.

The device is compact and supports DIN rail mounting, which can save installation space and reduce costs. It can be widely used in smart agriculture, smart medical treatment, factory monitoring and other scenarios.
