Mode Declaration

net transparent transmission mode 

 

In this mode, the serial port device can send data to the specified server on the network through this module. The module can also accept data from the server and forward the information to the serial port device.

Users do not need to pay attention to the data conversion process between serial port data and network packets, only through simple parameter settings, data transparent communication between serial port devices and network servers can be achieved.

This module supports two Socket connections, Socket A and Socket B, which are independent of each other. Socket A supports TCP Client, TCP Server and UDP Client. Socket B support TCP Client and UDP Client
