WIZ127SR User’s Manual 

26 

modes  supports  both  of  Server  and  Client.  The  communication  process  of  each  mode  is  as 

below. 

 

TCP server mode Communication 

At the TCP Server mode, WIZ127SR waits for the connection requests. 

TCP  Server  mode  can  be  useful  when  the  monitoring  center  tries  to  connect  to  the  device 

(where WIZ127SR is installed) in order to check the status or provide the commands. In normal 

time WIZ127SR is on the waiting status, and if there is any connection request (SYN) from the 

monitoring  center,  the  connection  is  established  (ESTABLISH),  and  data  communication  is 

processed (Data Transaction). Finally connection is closed (FIN). 

In order to operate this mode, “Device IP”, “Subnet mask”, “Gateway” and “Local port” should be 

configured first. 

 

The Data transmission proceeds as follows, 

1.  The host connects to the WIZ127SR which is configured as TCP Server mode. 

2.  As  the  connection  is  established,  data  can  be  transmitted  in  both  directions 

–  from  the 

host to the WIZ127SR, and from the WIZ127SR to the host 

 

TCP client mode Communication 

If WIZ127SR is set as TCP Client, it tries to establish connection to the server. 

To operate this mode, “Device IP”, “Subnet mask”, “Gateway”, “Remote host”, and “Remote port” 

should be set. If “Remote host” has domain name, you should be confirmed the “DNS server” 

field. 

In  TCP  Client  mode,  WIZ127SR  can  actively  establish  a  TCP  connection  to  a  host  computer 

when power is supplied. 

 

The Data transmission proceeds as follows: 

1.  As power is supplied, WIZ127SR board operating as TCP client mode actively establishes 

a connection to the server. 

2.  If the connection is complete, data can be transmitted in both directions 

– from the host to 

the WIZ127SR and from WIZ127SR to the host 

 

Mixed mode Communication 

In this mode, WIZ127SR normally operates as TCP Server and waits for the connection request 

from the peer. However, if WIZ127SR receives data from the serial device before connection is 

established, it changes to the client mode and sends the data to the server IP. Therefore, at the 

mixed mode, the server mode is operated prior to the client mode. 

As like TCP Server mode, the Mixed mode is useful for the case that the monitoring center tries 

to connect to the serial device (in which WIZ127SR is used) to check device status. In addition
