2.3 UDP client mode 

 

Work at UDP mode, Module listen a UDP port, and pc listen a UDP port, when need to send data, UDP packet will

RS232
RS485

System

 

 

 

 

2.4 UDP server Mode 

Like the socket UDP server in pc API. Many to one data transfer supported, the data from uart/232/485 part will
