[Introduction]：Le module serveur à port série unique NE2-S1 est un module de port série vers Ethernet qui réalise une transmission transparente bidirectionnelle du port série et des données Ethernet. Les utilisateurs n'ont pas besoin de se soucier des détails spécifiques, et la conversion du protocole est effectuée à l'intérieur de l'appareil. Il dispose d'une variété de modes de passerelle Modbus et de modes de passerelle IoT MQTTC/HTTPC, qui peuvent répondre aux fonctions de mise en réseau de divers appareils/PLC série ; il adopte des normes de conception de qualité industrielle pour garantir la fiabilité des équipements. Ce module Ethernet utilise une interface à trou embouti de 1,27 mm et est de taille compacte, ce qui facilite l'intégration des utilisateurs dans le système.
| Serial Number | Pin Function | describe |
| 1 | RX_P | Ethernet receives RX+ signal; |
| 2 | RX_N | Ethernet receives RX- signal; |
| 3 | TX_P | Ethernet transmits TX+ signal; |
| 4 | TX_N | Ethernet transmits TX- signal; |
| 5 | NC | Default is floating; |
| 6 | NC | Default is floating; |
| 7 | TXD | For serial port data transmission, TTL level communication voltage is only supported at 3.3V. If 5V is connected, level conversion is required. |
| 8 | NC | Default is floating; |
| 9 | NC | Default is floating; |
| 10 | RXD | For serial port data reception, TTL level communication voltage is only supported at 3.3V. If 5V is connected, level conversion is required. |
| 11 | 485_EN | The serial port operates in full-duplex mode by default. If an external RS485 chip is connected, a 1k pull-down resistor is connected to this pin, and the pin function becomes an RS485 enable control pin. It is set high when the serial port sends data and low under normal conditions. |
| 12 | NC | Default is floating; |
| 13 | NC | Default is floating; |
| 14 | NC | Default is floating; |
| 15 | RST | External reset input, valid for more than 100ns when low; internal weak pull-up. |
| 16 | NC | Default is floating; |
| 17 | LINK | High: Network cable not connected; 2Hz square wave: Network cable connected normally but link not connected; Low: Network link connected successfully; |
| 18 | NC | Default is floating; |
| 19 | NC | Default is floating; |
| 20 | IO_RST | Factory reset pins, internal weak pull-up, can be connected to an external reset button, low level for 5~10s restores factory settings; low level for 200~800ms restarts the device; |
| 21 | NC | Default is floating; |
| 22 | TX_LED | The serial port data transmission LED indicator is set to high level by default and outputs a 10Hz square wave when transmitting data. |
| 23 | GND | Common ground terminal, negative power input terminal; |
| 24 | VCC1 | For DC 3.1~6V power supply with a positive input of 5.0V, the recommended power supply load capacity is 300mA or higher . |
| 25 | GND | Common ground terminal, negative power input terminal; |
| 26 | RX_LED | The serial port data receiving LED indicator is set to high level by default and outputs a 10Hz square wave when receiving data. |
| 27 | NC | Default is floating; |
| 28 | NC | Default is floating; |
| 29 | NC | Default is floating; |
| 30 | NC | Default is floating; |
| 31 | LINKLED | The 10M PHY indicator light goes low after successful PHY negotiation and flashes when data is being transmitted or received. |
| 32 | SPDLED | 100M PHY indicator light: pulls low after successful PHY negotiation, flashes when data is being transmitted or received; |
| 33 | NC | Default is floating; |
| 34 | NC | Default is floating; |
| 35 | VCC2 | 3.3V@50mA , with a maximum output capability of 50mA ; |
| 36 | GND | Common ground terminal, negative power input terminal; |
