1、Easy to Install: PC and ABS materials, lightweight and easy to carry. Flame retardant, safe and reliable. Embedded terminal takes up less space, while the rail mount can be inserted into the standard PZ30 distribution box. 2、Low in Voltage: Built in AC to low voltage DC module, the WiFi serial server can be directly connected to the mains, saving power adapter costs and making wiring more convenient. 3、Quick Communication: The serial device sends a series of data packets that comply with parameter configuration rules to the serial port of the IoT factory equipment, which can quickly set the parameters of the IoT factory equipment in one go. 4、Stable Connection: Supports the mutual conversion between for RTU and TCP, suitable for connecting serial devices that support the for RTU protocol with PC configuration software for communication. 5、Good Conversion: The data packets received by the device through the serial port are directly sent to the web server through the HTTP protocol, without the need for TCP Server development. Data storage and other operations can be achieved using scripting languages such as PHP and ASP, which is very practical for B/S architecture systems. 6、Data Transmission: The master function is used to actively initiate polling, query the status of devices, and then package the data into HEX format or JSON format to report to the server using TCP, UDP, HTTP, MQTT and other protocols, eliminating the tedious process of server initiated queries. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
