Product Description

Mgate3202 is a dual network port DIN-rail industrial Modbus gateway with 2 serial ports. It support serial port conversion to UDP, TCP, Modbus, HTTPD, WebSocket, MQTT and other protocols, and can realize conversion between Modbus RTU/ASCII and Modbus TCP protocols.This product provides 2x100M copper ports and 2×RS232/485 serial ports, support dual DC 9~60V redundant power input, the power supply connection has no polarity, and adopts standard Din-rail installation method to meet the needs of various network sites.

The product support 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, system management, serial port restart,etc. Support 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 achieve Serial port to Ethernet or Modbus TCP protocol. Support one-click restart or factory reset. The hardware adopts high-standard industrial protection design, with selected industrial-grade components and high-strength aluminum alloy casing, which is sturdy and durable; low power consumption, wide temperature and wide voltage design, fanless casing for heat dissipation, and support -40℃~+85℃ operating temperature, passed strict safety regulations and EMC tests to meet the application needs of harsh industrial environments. Products 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 network ports can be configured as two independent network segments or cascade ports
  3. Serial port Support 300bps-460800bps baud rate optional
  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 Support up to 32 session connections, and support 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 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 certificate verification, ensuring connection security
