Convert Server has two TCP/UDP Socket: Socket A and Socket B. Serial data written to the Convert Server ,
will be sent to the Socket
A
and B simultaneously; TCP/UDP data that Convert Server receives through either
Socket
A
or B,will be sent to the serial port.
Dual Socket through different settings, you can achieve a variety of network interconnect. When the Convert
Server shipped only open Socket A, Socket B default is not to connect, if the user needs to use, please set by
AT
commands.

Socket
A
has three work mode: TCP Server, TCP Client, UDP.The setting method, please refer to the
AT+NETP command instruction.
When Socket
A
configured as TCP Server, it supports Multi-TCP link connection, and maximum 32 TCP
clients permitted to connect to Socket A.
Multi-TCP link connection will work as following structure:
Upstream: All dates from different TCP connection or client will be transmitted to the serial port as a
sequence.
Downstream: All data from serial port (user) will be duplicate and broadcast to every TCP connection or
client.

With variety work mode, socket B can provide users with flexible data transfer methods.For example, Socket
B can connect to a remote server in order to achieve remote control.
