Product Description

IEM308-DEMO-8D485 is a dual-port 8* RS232 / 485 embedded Ethernet serial port server, used with IEM308-8D core module. The product provides 2*100 MB Ethernet interfaces and 8* RS232 / 485 serial ports, support DC9~48V power input, using embedded installation mode, to meet the needs of a variety of industrial bus or network field. The hardware adopts low power consumption, wide temperature, wide pressure design, selected industrial components, using high performance and low power processor, support-40℃ ~ + 85℃ working wide temperature, through strict safety regulations and EMC test, suitable for various harsh field environment. The products can be widely used in industrial automation, comprehensive energy, intelligent transportation, smart city, smart mining and other fields.

The IEM308-8D core module supports WEB configuration with a variety of network management functions, Such as serial port / network working mode, serial port forwarding, network card mode, DNS, access control, IP / MAC filtering, log management, mail alarm, SNMP alarm, system management, serial port restart, system management, etc.; Support for multiple conversion modes, such as Modbus RTU Master/Slave, Modbus ASCII Master/Slave, UDP Client/Server, TCP Client/Server, UDP Multicast, RealCOM_MCP/CCP/MW, Pair Connection Master/Slave, HTTPD Client, WebSocket Client, MQTT, Implement the serial port to Ethernet or Modbus TCP protocol

Features and Benefits

Dual network ports can be configured as two separate network segments or cascade ports

Serial port support 300bps-460800bps port rate is optional

Support UDP Client / Server / Multicast mode, and can realize point-to-point, point-to-many or many-to-many communication through UDP protocol, fast and efficient

It supports TCP Client / Server mode, establishes session connection through TCP protocol, TCP Client supports up to 16-way session connection, TCP Server supports up to 32-way session connection, and supports RFC2217 instructions to dynamically modify communication parameters such as serial port and portport rate

Support Pair Connection Master / Slave mode, devices can be used in pairs, easy to operate

Support the WebSocket Client mode for two-way communication with the WebSocket server

Support RealCOM MCP / CCP / MW mode, mapping network for local COM, seamless connection

Support HTTPD Client mode and can perform GET or POST operation with HTTPD server

Support the WebSocket Client mode for two-way communication with the WebSocket server

Support serial port forwarding, realize transparent data transmission between serial ports and other serial ports, and provide one-directional forwarding / receiving and two-directional forwarding direction control

Multiple subcontracting mechanisms are supported to convert serial port data into Ethernet data packets according to the data length or time, to meet the real-time needs of different networks

Support frame head and tail mode, serial port can filter data frames according to the start and end bytes of the frame

Support for registration packages and heartbeat packages to realize connection verification and connection status detection

Support Modbus virtual ID, map Modbus slave real ID to virtual ID for data communication, and avoid slave ID duplication

Support DES / 3 DES / AES / RC2 / RC4 / RC5 / BlowFish and other data encryption algorithms to ensure the security of data

Support SSL (TLS1.0/1.1/1.2) connection encryption, one-way / two-way certificate verification, to ensure the security of the connection

Support for HTTP / HTTPS / SSH / TELNET access control, along with IP / MAC address filtering

Support device restart, login event, configuration change, password change and other events alarm, support email and SNMP alarm mode

Support serial port communication parameters, working mode, sending and receiving frame number statistics

Support log local storage, network storage, and serial port log output

Support serial port / device restart, restore factory setting, device upgrade and NTP client
