The E-Lins 4g sim card router can convert the RS-232/485 serial port into TCP/IP network interface and realize the two-way transparent transmission of data between the RS-232/485 serial port and TCP/IP network interface. Make serial port equipment can immediately have TCP/IP network interface function, connect the network for data communication, greatly expand the communication distance of serial port equipment.

Serial port server working mode
1.TCP/UDP communication mode: in this mode, 4g sim card router serial port servers are used in pairs, one as the server side and the other as the client side. The connection between them is established through IP address and port number to realize two-way transparent data transmission. This pattern is suitable for transforming the bus connection between two serial port devices into a TCP/IP network connection.
2. Use virtual serial port communication mode: in this mode, one or more converters establish a connection with a computer, supporting two-way transparent transmission of data. By the computer's virtual serial port software management below the converter, can achieve a virtual serial port corresponding to multiple converter. This mode is suitable for serial port device controlled by computer 485 bus or 232 device connection.
3. Based on network communication mode: under this mode, the application program on the computer is written based on SOCKET protocol, and directly choose to support SOCKET protocol on the converter Settings.

E-Lins 4g sim card router H685 has RJ45 port 1WAN+1LAN, optional support RS232 or RS485, 115200bps at most. Can works as server or client.
