Network transparent transmit mode:

4G Network Transparent Iot Ethernet Module Pluggble Terminals 0

  • In this mode, the user's serial device, through the module to send data to the specified server on the network. The module can also accept data from the server and forward the information to the serial device.
  • Users do not need to focus on serial data and network data packet data conversion process, just through a simple parameter settings, you can achieve data transparent communication between serial device and network server.
  • The CX-4G module supports four socket connections, Socket A, Socket B, Socket C, and Socket D, which are independent of each other.
  • The CX-4G module supports four channels that are set to long and short links, and when set to long connections, the module remains connected when the module is connected to the server. When the short link is set only when the serial port has the data to send the connection, establish a connection without data transmission over the set time-out time automatically disconnect, used to save the server resources and traffic.4G Network Transparent Iot Ethernet Module Pluggble Terminals 1
