⑦ Factory Reset button

Factory reset button can recover configuration parameter to factory default values. To reset the
module’s parameters to factory default, hold down the factory reset button when you turn power
switch on.

⑧ Variable Resistor (VR)

You can control analog input value with variable resistor. The WIZ220IO’s analog input is
voltage type and its range is 0V to Vcc(5V). Also, its value was translated to 0~4095 as each
input port has 12-bit resolution.

3. Configuration Tool

The configuration tool supports below major functions. All functions of configuration tool can be
performed remote area through the Ethernet.

- Change module’s configuration.

- I/O monitoring and controlling

- Firmware uploading

- Webpage uploading

3.1. Basic description

Figure 8. Configuration Tool

- FW Version: It displays firmware version.

- Enable Serial Debug Mode: If this mode is checked, you can monitor the status and socket

message (listen OK, connect fail etc.) through serial terminal.

- Board List: If you click the “SEARCH” button, all the MAC address on a same subnet will be

WIZ220IO User Manual V1.0

- 13 -

displayed. When you check the “Direct IP Search” and enter the specified IP address, the
board list will display its MAC address.

- Direct IP Search: Direct IP Search can be used for searching WIZ220IO which is not

installed in the same subnet. If the Direct IP Search is checked, the configuration tool use the
TCP instead of UDP broadcast to search the module. Therefore, network information of the
module such as IP address, subnet mask and gateway address is required for the search.

[Warning] If module does not have valid netw ork information, Direct IP Search is not
available. If the module is connected to the NAT or private network, it is not possible
to connect 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”.

- Setting: This function is to complete the configuration change. If you select the MAC address

from the “Board List”, the current configuration values of the module will be displayed.
Change the configuration value and click “Setting” button to complete the configuration. After
that, the module will re-initialize with the changed configuration.

- Webpage: It is possible to upload ROM Image file to the internal flash memory of WIZ220IO.

For more information, refer to “3.6. Webpage Upload”.

- Upload: It is possible to upload new firmware file through the Ethernet. For more information,

refer to “3.5. Firmware Download”.

- Ping: It is used to test whether the WIZ220IO module is reachable across a network from

your PC with ICMP protocol. After inputting host IP address in new pop-up window, click the
“PING” button. Then, it will be displayed its result.

- Firewall: It controls your PC’s firewall configuration. If board list does not display even though

clicking search button, check your PC’s firewall.

- Exit: Close the configuration tool program.

3.2. Network Tab

In the Network Tab of the configuration tool, network information and the notification parameters can
be set. The network information is for a communication through the Ethernet such as an IP address, a
gateway address and a subnet mask. If the module cannot be assigned with the fixed information
from ISP provider, you can set the DHCP option. By setting DHCP option, the network information can
be assigned by DHCP server.
The notification option is a function for sending the I/O values to the specified host every specified
period. It is useful for acquiring data log.

WIZ220IO User Manual V1.0

- 14 -

Figure 9. Network Tab of the Configuration Tool

- IP Configuration Method: You can select STATIC or DHCP. The STATIC option can be

selected when your network resource can give the fixed IP address, and the DHCP option
can be selected when your network has DHCP server such as a router who has DHCP server
function.

- Local IP Address: IP address of the WIZ220IO module.

- Subnet Mask: Subnet mask of the WIZ220IO module.

- Gateway address: Gateway address of the WIZ220IO module.

[Warning] Be sure to input correct network information. If you input incorrect
information, it can cause network collision or mal-function.

- HTTP Port Number: You can change webserver’s listen port number. The HTTP default port

number is 80.

- Notification Options – Protocol: The WIZ220IO can send I/O values to the specified host.

This parameter is a protocol of sending data. The “TCP Server” waits for the connection trial
from the host, The “TCP Client” tries to connect to the host’s IP address and port number. At
the “UDP” mode, the connection establishment is not defined. After setting the IP address
and port number of the host, just send data.

- Listen Port Number: It is valid only on “TCP Server” mode. The WIZ220IO module will

accept connection with listen port number.

WIZ220IO User Manual V1.0

- 15 -

- Remote IP Address / Remote Port Number: It is valid on “TCP Client” and “UDP” modes.

Input the host IP address and port number.

- Keep TCP connection: If you check this option, the WIZ220IO module maintains the

connection as sending keep-alive packet. If you uncheck this option, the module closes the
connection after sending data.

- Time period to sending: It is possible to set the sending period. To disable notification

option, input ‘0’ to this parameter.

3.3. Serial Tab

Serial tab is for the UART configuration. The UART is used to display debug message and to output
the UART data through the webpage.

Figure 10. Serial T ab of the Configuration Tool

- Speed: It supports baud rate from 1200bps to 230400bps.

- Data Bit: It supports 7bit or 8bit of data bit.

- Parity: It supports odd, even and none option of parity.

- Stop Bit: It supports only 1bit.

- Flow: It supports flow control – none, RTS/CTS.

3.4. Input / Output Tab

Input/Output tab is for the I/O control and monitoring. When you click the “Update I/O Status” button, it
will be displayed I/O parameters at that time.
In the Digital parameters, a green indicator means port is asserted ‘HIGH’ and a gray indicator means
‘LOW’. Each port can be set ‘HIGH’ as checking checkbox in ‘Digital Output Control’ and click the
‘Update I/O Status’ button.
The Analog I/O has range from 0 to 4095 and it has voltage type. In the Analog input status, ‘4095’
means maximum input value that is same to ‘5V_Input’ (Vcc) value. However, analog output
maximum value ‘4095’ generates 4V. In other word, the analog output maximum value is 4V.

[Warning] At the digital input, if you set the switch on the base board, module recognizes it as
“low”. At the digital output, when the module is “low”, LED on the base board becomes on.
