Product Description

The Mgate3204 is a Din rail industrial Modbus gateway. It supports serial port conversion to UDP, TCP, Modbus, HTTPD, WebSocket, MQTT and other protocols, and can realize communication between Modbus RTU/ASCII and Modbus TCP protocols. This product provides 2*100M copper ports and 4*RS232/RS485 serial ports. It supports DC 9~60V dual power supply redundant input. There is no polarity on power supply connection.

The product supports WEB configuration of various network management functions, such as serial port/network working mode, serial port forwarding, network card mode, DNS, access control, IP/MAC filtering, log management, email alarms, SNMP alarms, serial port restart, system management, etc.; supports Modbus RTU Master/Slave, Modbus ASCII Master/Slave, UDP, TCP Client/Server, UDP Multicast, RealCOM_MCP/CCP/MW, Pair Connection Master/Slave, HTTPD Client, WebSocket Client, MQTT and other conversion modes to realize serial port to Ethernet network or Modbus TCP protocol. Supports one-click restart or factory reset. The hardware adopts high-standard industrial protection design, with industrial-grade components and high-strength aluminum alloy casing, which is sturdy and durable; Mgate3204 is featured with low power consumption, -40℃~+85℃ wide temperature and wide voltage design, fanless casing for heat dissipation, and passed strict safety regulations and EMC tests to meet the application needs of harsh industrial environments. The Modbus gateway can be widely used in industrial automation, integrated energy, smart cities, smart transportation, smart mines, smart factories and other fields.

Features and Benefits
  1. High-performance CPU processing power, Cortex-A7 core, running frequency up to 800MHz
  2. Dual ethernet ports can be configured as two independent network segments or cascade ports
  3. Serial port supports 300bps-460800bps baud rate range
  4. Support UDP and UDP Multicast mode. Point-to-point, point-to-multipoint or multipoint-to-multipoint communication can be achieved through UDP protocol, which is fast and efficient.
  5. Support TCP Client/Server mode, establishing session connections through TCP protocol. TCP Client supports up to 16 session connections, TCP Server supports up to 32 session connections, and supports RFC2217 instructions to dynamically modify communication parameters such as serial port baud rate
  6. Support Pair Connection Master/Slave mode, devices can be used in pairs, easy to operate
  7. Support Modbus RTU/ASCII Master/Slave mode to realize Modbus TCP and Modbus RTU/ASCII protocol conversion
  8. Support RealCOM_MCP/CCP/MW mode, maps the network to local COM, and seamlessly connects
  9. Support HTTPD Client mode and can perform GET or POST operations with HTTPD server
  10. Support WebSocket Client mode, enabling two-way communication with the WebSocket server
  11. Support multiple sub-packaging mechanisms, converts serial port data into Ethernet data packets according to data length or time, to meet the real-time needs of different networks
  12. Support frame header and tail mode. The serial port can filter data frames based on the start byte and end byte of the frame
  13. Support registration package and heartbeat package to realize connection verification and connection status detection
  14. Support Modbus virtual ID, mapping the real ID of the Modbus slave to a virtual ID for data communication to avoid duplication of slave IDs
  15. Support DES/3DES/AES/RC2/RC4/RC5/BlowFish and other data encryption algorithms to ensure data security
  16. Support SSL (TLS1.0/1.1/1.2) connection encryption, one-way/two-way certificate verification, ensuring connection security
  17. Support HTTP/ HTTPS/ SSH/ TELNET access control, and IP/ MAC address filtering
  18. Support event alarms such as device restart, login events, configuration changes, password changes, etc, and supports email and SNMP alarm methods
  19. Support serial port communication parameters, working mode, statistics of sent and received frames
  20. Support log local storage, network storage and serial port log output
  21. Support serial port/device restart, factory settings restoration, device upgrade and NTP client
