Appearance
RS485 + RS232 DTU (Y212)
The Y212 series products are data terminals that can realize mutual transmission between serial ports and network ports. They use dual-core high-performance MCU with a main frequency of up to 240MHz, support wide voltage (5~36V) power supply, and are equipped with two serial ports that can work simultaneously. Each serial port corresponds to two sockets, and each socket supports TCP/UDP transparent transmission, HTTP Client, MQTT and other protocols, and supports SSL/TLS data encryption to meet the requirements for data security.

Two Operating Modes:
AT Command Configuration Mode
Data received on the serial port is executed as commands, and data sent from the network is discarded. In command mode, parameters can be queried and set, and the device will revert to transparent mode after a restart.
Transparent Mode
Data received on the serial port is forwarded via Socket, which is the default mode when the device is powered on.
Users can send AT commands through serial communication with a computer or MCU to query and set the parameters of this product. Each command line can only contain one AT command, with a maximum length of 256 bytes per command.
