This is an RS232/485/422 device data acquisitor/IoT gateway designed for an industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to JSON, etc. Adopting RS232/485/422 and Ethernet interface with PoE function, it can be connected with screw terminals for power input by the power port (outer diameter: 5.5mm, inner diameter: 21mm). The rail-type case design, is small in size, easy to install, and cost-effective. It is very suitable for collecting the data of RS232/485/422 and sensors in the industrial field, including local network collection or uploading to the data that the cloud server autonomously collects and sends.

Software Features

• Support TCP server, TCP client, UDP mode, and UDP multicast. When used as a TCP client, it also supports TCP server functions. It supports 30 TCP connections as a TCP server and 7 destination IPs as a TCP client.
• The baud rate supports 1200~115200bps, the data bit supports 5~9 bits, and the parity bit can be in five ways: no parity, odd parity, even parity, mark, and space.
• Supports the function of sending MAC address on device connection, which is convenient for cloud management of devices.
• Provides a secondary development kit DLL development library for searching and configuring devices on the computer side.
• Support Web browser configuration, support DHCP to obtain IP dynamically, and DNS protocol to connect domain name server address.
• Support cloud remote search for devices, configure device parameters, and upgrade device programs.
• Support viewing the TCP connection status, and the data sending and receiving of the serial port. The virtual serial port also supports the monitoring function.

Advanced Software Features 

• Support Modbus gateway function, support Modbus RTU to Modbus TCP. It can support storage-type Modbus, which can automatically collect and store device data; it also supports non-storage-mode Modbus gateways.
• Support multi-host function: In the query mode of one question and one answer, it supports the network port to allow multiple computers to access the same serial port device at the same time.
• Support MQTT gateway function.
• Support JSON to Modbus RTU and 645-meter protocol, support upload data in HTTP POST, HTTP GET format.
• Support NTP protocol to obtain network time, which is used for serial port output, and the latter is used for protocol content upload.
• Supports custom heartbeat package and registration package functions: it can facilitate communication with the cloud and device identification.
• Supports the function that TCP requires password authentication to establish a connection to ensure connection security.
• Support the data transmission and delivery function with http, and the cloud can directly use the GET command of http to communicate with the serial port of the device.

Applications

• For connecting the device and the cloud terminal as the IoT gateway
• Electricity, smart instruments, and energy consumption monitor
• Remote monitoring and program download for various automation PLCs
• Various configuration software and equipment communication interface
• Networking of equipment in the field of access control and security
