Configuration Tool#

Description#

WIZnet 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.

WIZnet Configuration tool consists four sections

1) Common Configuration Section 2) Network Configuration Section 3) Serial Configuration Section 4) Option Configuration Section

You can set the Common Configuration, “IP” of Network configuration with “Module Name” and “Setting Password” of Option configuration section for WIZ550WEB.

Notice: You can set WIZ550WEB module through WIZnet Configuration Tool version 1.02 or the latest version.

Common Configurations#

Search#

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.

Setting#

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

  1. Select the MAC address of the device which you would like to modify in the “Search Window”
  2. Modify the settings according to your needs
  3. Click the “Setting” button and then "Password Input Windows" pop up
  • Default Password is "WIZnet"
  1. Input "Setting Password" and Click "OK" button
  2. The module will be initialized by a re-booting process
  3. To verify your settings, please click ‘Search’ button and view your new settings

F/W Uploading.#

Firmware will be uploaded through TFTP. Click “F/W Uploading” Button and a popup window will shows as follow.

Server IP : TFTP Server IP
Server Port : TFTP Server Port (TFTP default Port : 69)
File Name : Firmware File Name
Password : Setting Password

☞ WIZnet Configure tool does not supported TFTP server. So please use TFTP program separately.

Reset#

This is the function which makes Module reboot. This requires password to reboot.

Factory Reset#

All setting value is initialized to factory default, if the “Factory Reset” button is clicked. Factory default values of Module are listed below.

**CategoryItemValue**
NetworkLocal IP192.168.11.100
Local Gateway192.168.11.1
Local Subnet255.255.255.0

Exit#

Close the configuration tool program window.

Search Window#

If you click the “Search” button, all MAC addresses on the same subnet will be displayed.

Search Method#

Reserved

Firmware Version#

It displays the firmware version.

Network Configurations#

IP#

This section is for setting Module mode's network information

IP:
Module's IP Address
Gateway:
Module's Gateway Address
Subnet mask:
Module's Subnet Mask

☞ 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.

Options Configurations#

Module Name#

The device name is displayed in this area. User can use this name to distinguish this module with others

Password#

Currently active for WIZ550web: Field “Setting Password”.

In this area the password for updating the settings can be changed. Critical functions like “Setting”, “Firmware Upload”, “Reset” and “Factory Reset” need this password to try issued action and avoid unauthorized users' command. If the user wants to replace the current or default Setting Password by a new one, this field should be updated with the new one before clicking on the “Setting” button and entering the old Setting Password.

Please note: the default Setting Password is “WIZnet” (without the brackets).

WIZ550WEB AT Command Set#

This section provides a list of WIZ550WEB AT commands and their functions. Users can input commands and parameters through USART line. Every command starts with “AT”. Any other initial character will cause an error in return. Commands and parameters are all ASCII characters, i.e. when you input 'AT+NSTAT', you should input ASCII characters 'A', 'T', '+', 'N', 'S', 'T', 'A', 'T' and 'Enter Key' which is CR, LF (0x0d, 0x0A).

! All commands should be terminated with CR(0x0D), LF(0x0A)

Some parameters are mandatory and others are optional. Parameters must be entered in the order of format column given by the command tables. Although the optional parameter is not used, the comma delimiters ',' must still be included in the command. In most cases, valid commands return the character [S] and invalid inputs return [F]. The possible responses sent from WIZ550WEB to the user are described as Responses. Below are examples of user input. As you can see, WIZ550WEB return “\r\n” back instead of “\r”, which means user (host system) always handle '\r\n' as the only delimiter.

Input by UserAT\r\n (0x61 0x74 0x0d 0x0a)
Output from WIZ550WEB[S]\r\n (0x5b 0x53 0x5d 0x0d 0x0a)
