ⓕ Subnet : WIZ110SR‟s subnet mask
ⓖ Gateway : WIZ110SR‟s Gateway addressⓗ PPPoE ID/Password : If you select „PPPoE‟ mode, input ID/Password which you received
from ISP company.

ⓘ Server IP/Port : When WIZ110SR is set as “Client mode” or Mixed mode”, server IP andport should be set. WIZ110SR attempts to connect this IP address.

ⓙ Network 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 thedata communication without connection establishment.
The Network mode of WIZ110SR can be divided into TCP Server, TCP Client and Mixed
mode according to the connection establishing method. At the TCP server mode, WIZ110SR
operates as server on the process of connection, and waits for the connection trial from theclient. WIZ110SR 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 andClient. The communication process of each mode is as below.

<TCP server mode>

Figure 4. TCP Server mode

At the TCP Server mode, WIZ110SR waits for the connection requests.
Copyright © WIZnet All Rights Reserved

WIZ110SR | 11 page

TCP Server mode can be useful when the monitoring center tries to connect to the device(where WIZ110SR is installed) in order to check the status or provide the commands. In
normal time WIZ110SR is on the waiting status, and if there is any connection request (SYN)
from

the

monitoring

center,theconnectionisestablished(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.
As illustrated in the above figure, data transmission proceeds as follows,
1. The host connects to the WIZ110SR which is configured as TCP Server mode.
2. As the connection is established, data can be transmitted in both directions – from the hostto the WIZ110SR, and from the WIZ110SR to the host

<TCP client mode>

Figure 5. TCP Client mode

If WIZ110SR 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 number
should be set. If server IP had domain name, use DNS function.
In TCP Client mode, WIZ110SR can actively establish a TCP connection to a host computerwhen power is supplied.
As illustrated in the above figure, data transmission proceeds as follows:
1. As power is supplied, WIZ110SR board operating as TCP client mode actively establishes aconnection to the server.
2. If the connection is complete, data can be transmitted in both directions – from the host to
the WIZ110SR and from WIZ110SR to the host

Copyright © WIZnet All Rights Reserved

WIZ110SR | 12 page<Mixed mode>
In this mode, WIZ110SR normally operates as TCP Server and waits for the connection requestfrom the peer. However, if WIZ110SR receives data from the serial device before connection isestablished, it changes to the client mode and sends the data to the server IP. Therefore, atthe 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 WIZ110SR 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 thedevice.
.

ⓚ Use UDP mode

Figure 6. UDP mode

At the UDP mode, the connection establishment is not defined. Just set the IP address andport number of the peer and send the data.

ⓛ Use DNS : If DNS function is needed, check this option and input the domain name of DNS
server. DNS(Domain Name System) is the database system having information about IP addressand corresponding domain name. When connecting to domain name, you can use DNS functionof WIZ110SR. Input IP address of DNS server provided by ISP in DNS Server IP, and domainname in the Server (Domain)
If server has dynamic IP address, but domain name, if you use DNS function, you do not needto configure server IP address whenever it‟s changed.
.

ⓜ Direct IP Search
Direct IP Search can be used for searching WIZ110SR not installed in the same subnet.
If the Direct IP search is checked, the configuration tool use the TCP instead UDP broadcast to
Copyright © WIZnet All Rights Reserved

WIZ110SR | 13 page

search modules. Therefore, network information of the module such as IP address, subnet
mask and gateway is required for the search.
If you check Direct IP search, the field in which IP address is input, will be activated. In thisfield, input IP address of the module, and click “Search” button.

☞ If module does not have valid network information, Direct IP search is not available.
Check if module is connected to the NAT or private network. If so, it is not possible toconnect to the module from outside.

ⓝ Search
The Search function is used to search all modules existing on the same LAN. By using UDP
broadcast, all modules on the same subnet will be searched.
The searched module is displayed as MAC address in the “Board list”.

ⓞ SettingThis function is to complete the configuration change.
If you select the MAC address from the “Board list”, the default configuration value of themodule will be displayed. Change the configuration and click “Setting” button to complete
the configuration. The module will re-initialize with the changed configuration. Changed
value is saved in the EEPROM of the module. Thus, the value is not removed even thoughpower is disconnected.
The configuration value can be changed in below steps.
① Select the MAC address of which configuration value should be changed in the “Board list.
The values configured will be displayed.
② Change the value③ Click “Setting” button. The configuration change will be complete.
④ The module will be initialized to the changed values (re-booting is processed)⑤ To check configuration result, click „Search‟ button.

ⓟ Upload

ⓥ

Figure 8. Configuration Tool (Option Config.)ⓢ Inactivity time
After the connection is established, if there is not data transmission within the time definedin 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, theconnection is maintained even though there is no data transmission. In order to close theconnection, the „Close‟ command should be given.
This function can be used for more than two or more systems to connect to a WIZ110SR
module. If one system holds the connection to the WIZ110SR, other systems can not connect
to the module. If there is no data transmission during the time defined in Inactivity time, theconnection will be closed for other system to be connected.

Copyright © WIZnet All Rights Reserved

WIZ110SR | 16 page

Inactivity Time also can be useful for the case when the server system is unexpectedly shut
down. In this status, if there is not any data communication during the time defined in theInactivity time, WIZ110SR will close the connection and enter into waiting status.

ⓣ Data Packing Condition
You can designate how the serial data can be packed to send to the Ethernet.
In default mode, WIZ110SR 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 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 isconverted to Ethernet packet. If new data is received, the time is re-calculated and thereceived data is saved in the serial buffer. Time condition can be utilized when theserial data size is variable and has no ending character, but needs to be delivered inframe 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, andtransmitted to Ethernet. The character can be specified in Hex formation. (The value is„0‟, this option is not used)
Any 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.

ⓤ Password„Password‟ function is for blocking client‟s access which is not allowed.
‟Password‟ function can be operated only in „TCP Server‟ mode. When „password‟ function
operates, clients should input password to access.
