  Operating modes 

WIZS2E  module  supports  TCP  server,  TCP  client  and  UDP  modes;  Below  demonstrate 

these operating modes.

Figure 3-1 TCP server mode diagram 

Figure 3-1 shows, W7500S2E-R1 module open a local port to listen TCP requests in TCP server 
mode.  The  default  port  number  is  5000  and  it  is  waiting  for  client  connections.  After  the 
connection has created, it will start data communication.

Figure 3-2 TCP client mode diagram 

According to figure 3-2, W7500S2E-R1 module will starts to connect to TCP server that set in 
the  module  for  TCP  client  mode.  If  connection  fails,  client  will  base  on  reconnection  setting 
condition  and  try  to  connect  with  the  TCP  server.  After  its  connected,  it  will  start  data 
communication.
