In today's era of rapid development of the Internet of Things, the network port has become a hot term with its advantages of long transmission distance and high communication rate. Industrial automation has also gradually upgraded to automation and intelligence. The networking of serial port devices has become a major trend in the Internet of Things.

The serial port to network port device plays an important role in data conversion here. It transmits various field bus data of the industrial site through the TCP/IP protocol, realizes the rapid upload of data to the cloud, and has the ability to process edge data.

The TTL to Ethernet integrated super network port is different from the traditional Ethernet module. It is smaller in size, more integrated, more powerful, and more conducive to users to integrate into their own systems.

Our company's newly launched NE2-T1M has the advantage of small size, with an overall size of 32.5mm*17.5mm*16.5mm. Compared with the traditional network port, this module adopts a metal shielding cover full-cover design, and a grounding terminal is left in the design to release interference sources such as static electricity to the PCB board, with stronger anti-interference ability. The integrated network port, all pins are placed at the bottom, and users can treat it as a device when designing the PCB, without considering the high-speed part of the circuit, which brings great convenience to user integration and seamlessly fits the PCB board.

As an IoT terminal, the module has strong network compatibility and supports access to the Internet via TCP, UDP, MQTT, and HTTP, without worrying about protocol matching issues. It supports 2 full-function links that can run simultaneously without affecting each other. In order to reduce the complexity of users accessing the MQTT server, access points for Alibaba Cloud, Baidu Cloud, Tencent Cloud, Huawei Cloud, and standard MQTT protocols are designed to facilitate users to quickly debug.

Comes with ModBus gateway mode.

Simple protocol conversion, the device automatically distinguishes between ModBus TCP protocol and ModBus RTU protocol, and actively discards data that is not a ModBus protocol, so that the data of the entire system is cleaner and tidier, reducing the probability of data mis-triggering.

Multi-host gateway, the device can handle up to 5 Modbus TCP hosts in multi-host mode. When multiple Modbus hosts access at the same time, the Modbus gateway will schedule the bus occupancy, thereby solving the bus conflict problem and reducing the problem of data request failure. (The RS-485 bus can only process one request at a time, while the multi-host mode will sort and process according to the TCP request, and other links will wait)

Storage gateway mode: the storage gateway not only arbitrates the bus data but also stores repeated read instructions. When different hosts request the same data, the gateway does not need to inquire about the RTU device register status multiple times, but directly returns the cached data in the storage area, which greatly improves the gateway's multi-host request processing capability and shortens the time consumed by the entire request process. Users can customize the storage area instruction polling interval and instruction storage time according to their needs.

Configuration gateway mode: the gateway automatically polls the RTU device register according to the pre-configured ModBus instructions, and the instructions in the non-storage table will directly operate the RTU device. Frequently read instructions can be stored in the gateway in advance, and can be polled like a serial port device when powered on. The host request data can be returned immediately, which greatly shortens the response time.

Master upload mode: in client mode (TCP client, UDP client, MQTT client, HTTP client), the gateway will automatically poll the instructions in the storage instruction table and upload them to the server. The feedback format (Modbus RTU format or Modbus TCP format) and instruction polling interval (0-65535ms) can be selected according to needs.
