WIZ550S2E Configuration tool is an application program which is based on java and can be used in most OS platforms including Windows, MAC OS and Linux. Please download .jar file and execute it over Java Virtual Machine.
WIZ550S2E Configuration tool consists four sections
- Common Configuration Section
- Network Configuration Section
- Serial Configuration Section
- Option Configuration Section
The Search function is used to search for all existing modules on the same LAN. By using UDP broadcast, it finds all modules on the same subnet, and found devices will be listed in the “Serial to Ethernet” tree(Search Window) with its MAC address.
This function is used to apply your configurations.
When you select the MAC address from the “Search Window”, the default value of the module will be displayed. Modify your configurations and click “Setting” button to apply your settings. The module will re-initialize and save the changed configurations.
Users can change the configurations by following the steps below.
Firmware will be uploaded through TFTP. Click "F/W Uploading" Button and
then pop up windows following figures.
Server IP : TFTP Server IP
☞ WIZ550S2E Configure tool is not supported TFTP server. So you use TFTP program separately.
This is the function which makes WIZ550S2E reboot. This requires "Setting Password".
All setting value is initialized to factory default, if the “Factory
Reset” button is clicked. Factory default values of WIZ550S2E are listed

Close the configuration tool program window.
If you click the “Search” button, all MAC addresses on the same subnet will be displayed.
It displays the firmware version.
This field shows the current status of network connection.
This section is for setting WIZ550S2E mode's network information
☞ If you are unclear about your Local IP, Subnet Mask, Gateway information, you have to get this information from your network administrator. If the IP address is not correct, IP collision or network problems may occur.
This section is for setting WIZ550S2E's Port information.
Client / server / mixed TCP establishes connection before data communication, but UDP processes the data communication without connection establishment. The network mode of WIZ550S2E can be divided into TCP Server, TCP Client and Mixed mode according to the connection establishing method. During TCP server mode, WIZ550S2E operates as the server and waits for the connection trial from the client. WIZ550S2E operates as the client in TCP Client mode and tries to connect to the server’s IP and Port. Mixed mode supports both Server and Client. The communication process of each mode is as below.
During the TCP Server mode, WIZ550S2E waits for the connection request. TCP Server mode can be useful when the monitoring center attempts to connect to the device, while WIZ550S2E is installed, in order to check the status or provide commands. Normally WIZ550S2E is on the waiting status, and if connection request (SYN) from the monitoring center is received, the connection is established (ESTABLISH), and data communication is processed (Data Transaction), and finally connection is closed (FIN). In order to operate this mode, “Device IP”, “Subnet mask”, “Gateway” and “Local port” should be configured first.
For TCP server mode communication, all network configurations including Local IP, Subnet, Gateway and Local port number should be set correctly.
The Data transmission proceeds as below.
- The host connects to the WIZ550S2E which is configured as TCP Server mode.
- As the connection is established, data can be transmitted in both directions
If WIZ550S2E 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 a domain name, you should use the “DNS server” field. In TCP Client mode, WIZ550S2E can actively establish a TCP connection to a host computer when power is supplied.
The Data transmission proceeds as below:
- As power is supplied, WIZ550S2E board operating as TCP client mode actively establishes a connection to the server.
- If the connection is complete, data can be transmitted in both directions
In this mode, WIZ550S2E normally operates as TCP Server and waits for
the connection request from the peer. However, if WIZ550S2E 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,
during mixed mode, the server mode is operated prior to the client
Like TCP Server mode, the Mixed mode is useful in case where the monitoring center attempts to connect to the serial device, while WIZ550S2E is used, to check the 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.
UDP is not a connection oriented protocol but the communication port
should be defined well. If UDP mode is selected, the data from serial
interface can be defined where to deliver via the “Remote host” and
“Remote port.” The WIZ550S2E can also be defined where to receive
Ethernet data from via the “Remote host” and “Local port” definition.
If the data destination and source are the same, the two IP addresses will also be the same. Please note that the destination and source are using the same port.
When there is no data transmission, the connection will close
automatically after the specified inactivity time. If the default value
‘0’ is set as the Inactivity time, the network connection is
maintained even though there is no data transmission. In this case, you
should use the ‘Close’ command to close the connection.
This function is useful when there are two or more systems connected to the WIZ550S2E module. If one system is connected to the WIZ550S2E, other systems cannot connect to the module simultaneously. Therefore, the inactivity time should be set and the other system can connect to the module after the inactivity time is elapsed.
Inactivity Time can also be used if the server system unexpectedly shuts down. In this case, there is no data communication, and WIZ550S2E will close the connection and enter into waiting state if the defined inactivity time elapses.
This is the interval time which WIZ550S2E tries to connect again after connection is closed. This is valid only in "Client mode" or "Mixed mode" having data from serial prior to TCP connection is established.
This menu is used for setting the serial port.
Baud Rate :
This function is for module configuration through network with the configuration tool serial communication. The serial command mode is enabled as default.
Normally, data received from UART are sent to Ethernet immediately. But in many cases, users want to send data as a chunk of the whole frame without separated ones. This option is for packetizing data into one frame.
The device name is displayed in this area.
User can use this name to distinguish this module with others
This is password field for authentication.
This decides how to obtain IP address. If user selects "Use DHCP" then WIZ550S2E will obtain IP address dynamically by DHCP operation. Otherwise, it will operate in static mode.
This is valid in TCP Client mode only. Normally, TCP Client mode has to
know its peer system's IP address. But there are some cases where the IP
address is unknown and especially when the IP address change
In this case, DNS function is needed.
User has to select “Use DNS” option and set DNS Server IP address and peer systems' Domain name in string. Put DNS Server IP, provided by ISP, into “DNS Server IP” field and peer system's Domain name into “Domain” field.
