[Введение]：Серверный модуль с одним последовательным портом NE2-S1-TB представляет собой модуль последовательного порта для Ethernet, который реализует двунаправленную прозрачную передачу данных последовательного порта и Ethernet. Пользователям не нужно заботиться о конкретных деталях, а преобразование протокола выполняется внутри устройства. Он имеет различные режимы шлюза Modbus и режимы шлюза MQTTC/HTTPC IoT, которые могут соответствовать сетевым функциям различных последовательных устройств/ПЛК; он принимает стандарты проектирования промышленного уровня для обеспечения надежности оборудования. Этот модуль Ethernet использует интерфейс с штампованным отверстием диаметром 1,27 мм и имеет компактные размеры, что упрощает интеграцию пользователей в систему.
| No. | Pin Function | Description |
| 1 | RX_P | Ethernet receives RX+ signal; |
| 2 | RX_N | Ethernet receives RX-signal; |
| 3 | TX_P | Ethernet sends TX+ signal; |
| 4 | TX_N | Ethernet sends TX-signal; |
| 5 | NC | Default is left floating; |
| 6 | NC | Default is left floating; |
| 7 | 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; |
| 8 | NC | Default is left floating; |
| 9 | NC | Default is left floating; |
| 10 | RXD | The serial port receives data, and only supports TTL level communication voltage; 3.3V, if connected to 5V, level conversion is required; |
| 11 | 485_EN | The serial port works in full-duplex mode by default. If an external 485 chip is connected, the pin is connected to a 1k pull-down resistor. 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; |
| 12 | NC | Default is left floating; |
| 13 | NC | Default is left floating; |
| 14 | NC | Default is left floating; |
| 15 | RST | External reset input, valid for low level above 100ns, internal weak pull-up; |
| 16 | NC | Default is left floating; |
| 17 | LINK | High: The network cable is not connected; 2Hz square wave: The network cable is connected normally but the link is not connected; Low: The network link is connected successfully; |
| 18 | NC | Default is left floating; |
| 19 | NC | Default is left floating; |
| 20 | IO_RST | Restore factory pin, internal weak pull-up, can be connected to an external reset button, the low level lasts for about 5~10s to restore the factory settings; the low level lasts for 200~800ms to restart the device; |
| 21 | NC | Default is left floating; |
| 22 | TX_LED | Serial port data transmission LED indicator, outputs high level by default, and outputs 10Hz square wave when sending data; |
| 23 | GND | Common ground terminal, negative terminal input of power supply; |
| 24 | VCC1 | DC 3.1~6V (VCC1) power supply positive input, such as 5.0V power supply, must use the VCC pin, and the 5.0V power supply load capacity is recommended to be more than 300mA. Only one of the two power supply methods can be selected. Remember not to supply power with VCC2 at the same time; |
| 25 | GND | Common ground terminal, negative terminal input of power supply; |
| 26 | RX_LED | The serial port data receiving LED indicator light outputs high level by default and outputs a 10Hz square wave when receiving data; |
| 27 | NC | Default is left floating; |
| 28 | NC | Default is left floating; |
| 29 | NC | Default is left floating; |
| 30 | NC | Default is left floating; |
| 31 | LINKLED | 10M PHY indicator, pulls low after PHY negotiation is successful, and flashes when data is sent and received; |
| 32 | SPDLED | 100M PHY indicator, pulls low after PHY negotiation is successful, and flashes when there is data being sent and received; |
| 33 | NC | Default is left floating; |
| 34 | NC | Default is left floating; |
| 35 | VCC2 | DC 3.0~3.6V (VCC2) For 3.3V power supply, it is recommended to use the VCC2 pin (VCC1 pin is not recommended) and the 3.3V power supply load capacity is recommended to be more than 300mA; only one of the two power supply methods can be selected, remember not to use it with VCC1 supplies power at the same time; |
| 36 | GND | Common ground terminal, negative terminal input of power supply; |
