NE2-S1 TTL serial port to Ethernet patch module communication data transparent transmission serial port to network port rj45 edge acquisition modbusTCP to RTU MQTT communication network
[Introduction]：NE2-S1 single serial port server module is a serial port to Ethernet module that realizes bidirectional transparent transmission of serial port and Ethernet data. Users do not need to care about the specific details, and the protocol conversion is completed inside the device. It has a variety of Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, which can meet the networking functions of various serial devices/PLCs; it adopts industrial-grade design standards to ensure equipment reliability. This Ethernet module uses a 1.27mm stamp hole interface and is compact in size, making it easy for users to integrate into the system.
| Project | Instruction |
| Operating Voltage | DC 3.1~6V (VCC1) If the power supply is 5.0V, the VCC pin must be used, and the load capacity of the 5.0V power supply is recommended to be above 300mA. DC 3.0~3.6V (VCC2) If the power supply is 3.3V, it is recommended to use the VCC2 pin (it is not recommended to connect the VCC1 pin) and the 3.3V power supply load capacity is recommended to be above 300mA. Only one of the two power supply methods can be selected, and remember not to supply power at the same time. |
