[Introducción]：El módulo de servidor de puerto serie único NE2-T1B es un puerto de súper red que realiza una transmisión transparente bidireccional de datos desde el puerto serie al puerto Ethernet. Los usuarios no necesitan preocuparse por detalles específicos y la conversión del protocolo se completa dentro del servidor. Tiene una variedad de modos de puerta de enlace Modbus y modos de puerta de enlace IoT MQTTC/HTTPC; Adopta estándares de diseño de grado industrial para garantizar la confiabilidad del dispositivo. El producto viene con una interfaz RJ45, paquete de pines y es fácil de usar debido a su tamaño compacto (también conocido como "superpuerto de red"). Puede cumplir con las funciones de red de varios dispositivos seriales de nivel TTL y MCU/PLC.
| No. | Pin | Function |
| 1 | VCC | Positive power input, supports 3~6V input; |
| 2 | GND | Common ground terminal, negative terminal input of power supply; |
| 3-5 | NC | Default is left floating; |
| 6 | IO_RST | Restore factory pin, internal weak pull-up, can be connected to an external reset button, the low level lasts about 5~10s to restore the factory settings; the low level lasts 200~800ms to restart the device |
| 7 | LINK | Off: The network cable is not connected; Flashing: The network cable is connected normally but the link is not connected; Steady on: The network link is connected successfully; |
| 8 | POWER | Off: The device is not connected to the power supply; Steady on: The device is connected to the power supply. |
| 9 | LED_TXD | Serial port data sending LED indicator, outputs high level by default, and outputs 10Hz square wave when sending data. |
| 10 | TXD | When sending data through the serial port, the TTL level communication voltage only supports 3.3V. If it is connected to 5V, level conversion is required. |
| 11 | RXD | The serial port receives data, and the TTL level communication voltage only supports 3.3V. If it is connected to 5V, level conversion is required. |
| 12 | 485_EN | The serial port works in full-duplex mode by default. If an external 485 chip is connected, the pin is connected to an external 1k pull-down resistor, and the pin function becomes the RS485 enable control pin. When the serial port sends data, it is set high and the normal state is low. |
| 13 | LED_RXD | Serial port data receiving LED indicator, outputs high level by default, and outputs 10Hz square wave when receiving data |
| 14 | RST | External reset input, valid for low level above 100ns, internal weak pull-up; |
