10) Network Setting Method
Select IP setting mode, you can select one of Static, DHCP.
(PPPoE mode is not supported at current version)
- Using the follow IP Address (Static)
This is option for setting WIZ107SR module’s IP with static IP address. Firstly, select
MAC address which you wanted to set as static IP in the board list. Then “Device IP,
Subnet, Gateway box” will be enabled. Input Static IP address and click “setting”
button. Then set the IP address as you want.
- DHCP
Set this option to use DHCP mode. Firstly, check ‘DHCP’ and click ‘Setting’ button. If
IP address is successfully acquired from DHCP server, the MAC address will be

WIZ107SR User Manual (WIZnet Co., Ltd.) 10
displayed on the configuration window. (It takes some time to acquire IP address
from DHCP server)
When a module on the board list is selected, IP address, Subnet mask and Gateway
are displayed. If module could not acquire network information from DHCP server, IP
address, Gateway Address and Subnet mask will be initialized to 0.0.0.0.
11) Network Operation Mode
Client / server / mixed : This is to select the communication method based on TCP. TCP
is the protocol to establish the connection before data communication, but UDP just
processes the data communication without connection establishment. The Network
mode of WIZ107SR can be divided into TCP Server, TCP Client and Mixed mode
according to the connection establishing method. At the TCP server mode, WIZ107SR
operates as server on the process of connection, and waits for the connection trial from
the client. WIZ107SR operates as client at the TCP Client mode on the process of
connection, and tries to connect to the server’s IP and Port. Mixed 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, WIZ107SR waits for the connection requests.
TCP Server mode can be useful when the monitoring center tries to connect to the
device (where WIZ107SR is installed) in order to check the status or provide the
commands. In normal time WIZ107SR 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, Local IP, Subnet, Gateway Address and Local Port
Number should be configured first.
The Data transmission proceeds as follows,
1. The host connects to the WIZ107SR 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 WIZ107SR, and from the WIZ107SR to the host
<TCP client mode Communication>
If WIZ107SR is set as TCP Client, it tries to establish connection to the server.
To operate this mode, Local IP, Subnet, Gateway Address, Server IP, and Server port

WIZ107SR User Manual (WIZnet Co., Ltd.) 11
number should be set. If server IP had domain name, use DNS function.
In TCP Client mode, WIZ107SR 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, WIZ107SR 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 WIZ107SR and from WIZ107SR to the host
<Mixed mode Communication>
In this mode, WIZ107SR normally operates as TCP Server and waits for the connection
request from the peer. However, if WIZ107SR 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 WIZ107SR is used) to check device
status. In addition to this, if any emergency occurs in the serial device, the module will
change to Client mode to establish the connection to the server and deliver the
emergency status of the device.
<Use UDP mode>
UDP is not a connection oriented protocol. But the communication port should also be
defined well. If the UDP mode is selected, the data from serial interface can be defined
where to delivery via the “Sever IP Address” and “Port”, and the WIZ107SR can also be
defined where to receive Ethernet data from via the “Remote Peer IP Address” definition.
If the data destination and source are the same, the two IP address will also be the
same. Please note the destination and source are using the same port.
12) DDNS Setting
DDNS function is not supported at current version.

WIZ107SR User Manual (WIZnet Co., Ltd.) 12
2.1.2 Serial Configuration
Figure 7. WIZ107SR Configuration Tool (Serial Configuration Page)
1) Enable debug message output
If this mode is checked, you can monitor the status of module and socket message like
listen OK, connect fail etc. through serial terminal. If debug mode is on, debug message
can cause abnormal operation of the serial device. Therefore, just use this mode only for
debug mode.
2) COM port Setting
The parameters of COM port of WIZ107SR are listed well in this page. Users can set the
COM port of WIZ107SR by selecting the value of each parameter in the drop down list.
☞ By clicking the “Setting” button, changed value can be applied.
3) Serial data packing condition settings
You can designate how the serial data can be packed to send to the Ethernet.
In default mode, WIZ107SR checks the serial buffer and sends any received data to
Ethernet without any standard. Therefore, the data can be regarded as error data due to

WIZ107SR User Manual (WIZnet Co., Ltd.) 13
inconsistent data length. In order to solve this problem, the data from serial can be
packed according to the specified condition before sending to Ethernet. The condition is
as below.
Time: If there is not any new data during designated time, all data in the serial buffer is
converted to Ethernet packet. If new data is received, the time is re-calculated and
the received data is saved in the serial buffer. Time condition can be utilized when
the serial data size is variable and has no ending character, but needs to be
delivered in frame unit. (If the value is ‘0’, option is not used)
Size: When data is collected as much as the defined size in the serial buffer, it is
transmitted to Ethernet (If the value is ‘0’, option is not used)
Character: The data is collected in the serial buffer until specified character is received,
and transmitted to Ethernet. The character can be specified in Hex formation.
(The value is ‘0’, this option is not used)
One of three conditions is satisfied, the data is transmitted to the Ethernet.
Ex) Delimiter: Size=10, Char=0x0D
Serial data : 0123456789abc
Ethernet data : 0123456789
☞ “abc” data remains in the serial buffer of module.
4) Serial command mode switch code
This function is for module configuration not through network with Configuration tool but
through serial communication. At the default status, the serial command mode is disabled.
When you want to set via serial communication, check “enable”.

WIZ107SR User Manual (WIZnet Co., Ltd.) 14
2.1.3 Option Configuration
Figure 8. WIZ107SR Configuration Tool (Option Configuration Page)
1) Timer interval
- Inactivity Timer : The connection holding period when no data transmission.
- Reconnection Interval : The connection retry interval (client mode only)
After the connection is established, if there is not data transmission within the time
defined in Inactivity time, the connection is closed automatically. The default value is ‘0’. If
‘0’ is set, this function is not activated. In this default setting, the connection is maintained
even though there is no data transmission. In order to close the connection, the ‘Close’
command should be given.
This function can be used for more than two or more systems to connect to a WIZ107SR
module. If one system holds the connection to the WIZ107SR, other systems cannot
connect to the module. If there is no data transmission during the time defined in
Inactivity time, the connection will be closed for other system to be connected.
