2.1 Block Diagram
Figure 1. Block Diagram
WIZ110SR is a protocol converter that transmits the data sent by serial equipment as TCP/IP
data type and converts back the TCP/IP data received through the network into serial data to
transmit back to the equipment. When the data is received from serial port, it is sent to
W5100 by MCU. If any data is transmitted from Ethernet, it is received in the internal buffer
if W5100, and sent to the serial port by MCU. MCU in the module controls the data according
to the configuration value that user defined.

Figure 2. Configuration Tool (Network Config)
ⓐ Version : Displays firmware version.
ⓑ Enable Serial Debug Mode : If this mode is checked, you can monitor the status and
socket message of WIZ110SR (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.
ⓒ Board List : If you click “Search” button, all the MAC addresses on a same subnet, will be
displayed.

ⓓ Local IP/Port : WIZ100SR’s IP address and Port number for network connection
ⓔ Subnet : WIZ110SR’s subnet mask
ⓕ Gateway : WIZ110SR’s Gateway address
ⓖ Server IP/Port : When WIZ110SR is set as “Client mode” or Mixed mode”, server IP and
port should be set. WIZ110SR attempts to connect this IP address.
ⓗ 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 address
and corresponding domain name. When connecting to domain name, you can use DNS function
of WIZ110SR. Input IP address of DNS server provided by ISP in DNS Server IP, and domain
name in the Server (Domain)
ⓘEnable DHCP Mode :
Set this option to use DHCP mode. First, check ‘Enable DHCP mode’ and click ‘Setting’ button.
If IP address is successfully acquired from DHCP server, the MAC address will be displayed on
the board list. (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.
ⓙ Network mode: client/server/mixed :
This is to select the communication method based on TCP – TCP Server, TCP Client, and Mixed.
TCP is the protocol to establish the connection before data communication, but UDP just
proceeds the data communication without connection establishment.
TCP Server operates as a server and TCP Client as a client on the connection establishment.
The mixed mode supports both of TCP server and client.
☞ This Network mode is just related to the connection establishment process. It just defines
who will request the connection first and who will be waiting for the connection requests.

<TCP server mode>
Figure 3. TCP Server mode
At the TCP Server mode, WIZ110SR waits for the connection requests.
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 from
the monitoring center, data communication is processed and connection is closed.
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 WIZ1q0SR 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 WIZ110SR, and from the WIZ110SR to the host
<TCP client mode>
Figure 4. TCP Client mode

Copyright © WIZnet All Rights Reserved
ASRB for SERIAL | 12 page
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 computer
when 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 a
connection 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
<Mixed mode>
In this mode, WIZ110SR normally operates as TCP Server and waits for the connection
request from the peer. However, if WIZ110SR 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 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
the device
ⓚ Use UDP mode
Figure 5. UDP mode
At the UDP mode, the connection establishment is not defined. Just set the IP address and
port number of the peer and send the data.

ⓛ 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
search modules. Therefore, network information of the module such as IP address, subnet
mask and gateway is required.
If you check Direct IP search, the field to input IP address will be activated. In this field,
input IP address of the module, and click “Search” button.
☞If module does not have valid network information, Direct IP search is not available.
ⓜ 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”.
ⓝ Setting
This function is to complete the configuration change.
If you select the MAC address from the “Board list”, the default configuration value of the
module will be displayed. Change the configuration and click “Setting” button to complete
the configuration. The module will re-initialize with the changed configuration.
The configuration value can be changed in below steps.
①Select the mac address of which configuration value should be changed in the “Board list.
The values configured will be displayed.
②Change the value
③Click “Setting” button. The configuration change will be complete.
④The module will be initialized to the changed values (re-booting is processed)
ⓞUpload
Firmware will be uploaded through network
☞After uploading the firmware, 20~30 seconds are required for initialization.
ⓟ Exit : Close the configuration tool program.

ⓡ Inactivity time
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 WIZ110SR
module. If one system keeps 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, the
connection will be closed for other system to be connected.
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 the
Inactivity 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 be sent to the Ethernet. There are 3
delimiters - time, size and character. If all of them are set as ‘0’, whenever the serial data is
arrived, they are sent to the Ethernet.
a. Time: Every designated time, serial data converted to Ethernet.
b. Size: Every designated data size, serial data converted to Ethernet.
c. Char: Every designated character, serial data converted to Ethernet. (It’s available only
Hex.)
When any of three delimiters is satisfied, data can be sent to the Ethernet.
Ex) Delimiter: Size=10, Char=0x0D
Serial data : 0123456789abc
Ethernet data : 0123456789
“abc” data remains in the serial buffer of module☞
