Overview:

RS232 to Ethernet, 5~18V power supply, one-button setting parameters, AT means to modify the module parameters in real time, automatically obtain IP, one button to restore factory settings. The module is a universal serial-to-Ethernet transparent transmission device, which can be connected to MCUs such as 51, AVR, PIC, ARM, etc. or other serial port (TTL) devices.

Features:

- Support 5V or 3.3V power supply, choose one;

- Serial TTL level, pin IO compatible with 3.3V and 5V voltage;

- Serial port baud rate supports 300 ~ 921600bps;

- The serial port supports full-duplex and half-duplex serial communication, and supports RS485 transceiver automatic switching;

- Two-way transparent transmission of serial data and network data;

- Support MDI/MDIX polarity automatic conversion, cross-connect or directly connect the network cable to any connection, the module automatically switches;

- Support DHCP to automatically obtain IP address and support DNS domain name access;

- Support KEEPALIVE mechanism;

- Support virtual serial port software, virtualize the network port into a computer COM port;

- Working mode supports TCP CLIENT, TCP SERVER, UDP CLIENT and UDP SERVER 4 modes;

- Supports 10/100M, full-duplex/half-duplex adaptive Ethernet interface, compatible with 802.3 protocol;

Set the serial port and network parameters of the chip through software and serial commands, and save the parameters after power off;

- Search and query all devices in the LAN through the UDP broadcast protocol to facilitate unified management of devices;
