Configuration Tool Manual-[EN]

Supported Languages

WIZnet’s configuration tool enables product search, product settings, and firmware upload via the network[1]. WIZ750SR is compatible with WIZ107/108SR and uses the same configuration tool[2].

The following screen will appear once the program is installed and opened.

Configuration Tool Layout​

Figure: Configuration Tool Layout

The configuration tool is composed of four sections. Details of each section are available below.

1. Icon Menu​

  • Device search, save settings, device reset and Etc.

2. Device List​

  • Lists the information of searched devices on the network

3. Configuration Tab​

  • Check and modify settings
  • Composed of three tabs: Network / Serial / Options

4. Progress Bar​

  • Shows the number of searched devices and the progress of firmware upload

Configuration Tool Details​

1. Icon Menu​

Figure: Menu Icons

  1. Program is operated in Windows only.

  2. If user has used either WIZ107/108SR, the same program can be used for WIZ750SR.

  • Searches for WIZ750SR on the same network.
  • Search can be done via UDP Broadcast[1] or TCP Unicast[2]
  • The UDP & TCP search pop-up windows is as below.
Figure: UDP Search
(broadcast)		Figure: TCP Search
(unicast)
  • Use TCP/UDP port 50001 to search WIZ750SR. Search can be unsuccessful due to firewall or virus protection software.

2) Save Settings​

  • Save the settings for WIZ750SR.
  • The settings will be applied through the configuration tool.
  • Then the module will automatically reboot.

3) Firmware Upload​

  • Use the firmware binary file provided from WIZnet to update WIZ750SR’s firmware
  • Then the module will automatically reboot.
  • The following pop-up will appear once the firmware upload is complete.
Figure: Popup Message - Firmware Upload Successfully
  • Use TCP/UDP port 50002 to upload firmware on to WIZ750SR. Firmware upload can be unsuccessful due to firewall or virus protection software.
  • The module will not work properly if the firmware is not correctly uploaded.

DO NOT TURN OFF POWER DURING FIRMWARE UPLOADING
IT CAN CAUSE MALFUNCTIONING

  1. UDP Broadcast Search: can search multiple devices

  2. TCP Unicast Search: can search only one device

4) Device Reset​

  • Reboots WIZ750SR.

5) Factory Reset​

  • Returns the settings of WIZ750SR to factory default.
  • Factory default setting of can be checked at WIZ750SR Factory Settings.
  • Then the module will automatically reboot.

6) Ping Test​

  • Ping Test checks whether or not the module and PC can communicate with each other.
  • If the module and PC can communicate via same network, the following ping reply will appear.
Figure: Ping Request and Reply

7) Firewall​

  • Opens the Windows control panel (firewall).
  • Use this icon to turn off the firewall if either the device search or firmware upload is unsuccessful.

8) Exit​

  • Ends the configuration tool.

2. Device List​

Figure: Device List

  • List of devices searched will appears.

    • Each device will be listed accordingly to each MAC addresses.

  • Users can check the below information by clicking the searched MAC address.

Model nameDescription

    • RS-422/485 versions will operate as ‘NONE’ shown above no matter which option is selected.

3) Serial Data Option Settings​

  • WIZ750SR provides multiple serial data packing options[1]. By using this option, user command frame or all other data can be collected and sent together.

Data packing options can be multi-selected but has priority as shown below.
Character => Size => Timer

  • Timer

    • Range: 0 ~ 65535 / Unit: milliseconds (ms)
      • Default: 0 (Not used)
    • Collects the data until the designated time is lapsed and sent together.Will not operate if set to '0'.

  • Size

    • Range: 0 ~ 255 / Unit: data length (number of bytes)
      • Default: 0 (Not used)
    • Collects the data until the designated data length is reached and sent together.
    • Will not operate if set to '0'.

  • Character

    • Range & Unit: 1-byte character (Hex code)
      • Default: 00 (Not used)
    • Collects the data until the designated character is entered and sent together.
    • The designated character will be included if the data size does not exceed the buffer size. The designated character will be excluded if the data size exceeds the buffer size.
    • Will not operate if set to '0x00'.

4) Serial Command Mode Switch Option Settings​

  • Serial command mode switch code: Enable

    • By enabling this option, the data communication mode (GW mode) will change to serial command mode (AT mode) when sending the command mode switch code via the serial data port.
      • Default: Enabled
    • Use the serial command mode composed of 2-byte to change settings.
    • The existing TCP connection will be lost if the mode changes to serial command mode.

  • Serial command mode switch code: Trigger Code

    • This is a 3-byte code for switching the mode from data mode to serial command mode.
      • Default: [2B][2B][2B] (+++)
    • Each byte value reads hex code only.
  1. Serial data can be collected according to the setting (character, size, or time) and be sent together.
info

Please take caution of the following when using Trigger code.

  1. It can only be recognized as switch code if there is a time gap of at least 500ms of no data communication time before and after the 3-byte command mode switch.
  2. The time interval for each byte of the 3-byte command mode switch code has to be at most 500ms.
  3. Do not end the command mode switch code[1] with CR((CR: Carriage return, ('\r', 0x0D) )) or LF((LF: Line feed, ('\n', 0x0A) )).
  4. The default interval of the time gap before and after the command mode switch code is 500ms. The operation is based on the timer value of the serial data packaging option.

5. Options Configuration Tab​

Figure: Options Configuration Tab

1) Inactivity Timer Settings​

  • Range: 0 ~ 65535 / Unit: seconds
    • Default: 0 (Not used)
  • If inactivity timer is set, connection is lost after the designated time without data communication is lapsed after the last data is sent.
  • This setting is for TCP Server or TCP Client mode and mixed mode.

2) Re-connection Interval Settings​

  • Range: 1 ~ 65535 / Unit: milliseconds (ms)
    • Default: 3000 (Use, 3 seconds)
  • The re-connection interval is for TCP Client Operation, including TCP Client of the mixed mode.
  • This option is requires in order to re-connect TCP communication in case it is lost.
  • The setting must be at least 1ms.

3) Search Identification Code Settings​

  • Range: Up to 8-bytes string
    • Default: Null (Not used)
  • The search identification code is for identifying the device search[2].
  • If this option is selected, the assigned code must be entered when searching devices.
Figure: Search ID code
(UDP broadcast search)

4) Connection Password Settings​

  • Range: Up to 8-bytes string
    • Default: Null (Not used)
  • Connection password is available for TCP server mode (including TCP server mode of the mixed mode).
  • TCP client must send the connection password character upon connecting to WIZ750SR in order for data communication.
  • TCP connection will be disconnected if the password does not match

  1. The serial command after switching modes must end with CR and LF.

  2. In cases when there are multiple devices in the same network.

5) TCP Keep-Alive Settings​

  • Send Keep-Alive: Enable

    • This option allows the connection status to be kept alive by sending the ‘keep-alive packet’ in all three TCP modes. (TCP server, TCP client, and TCP mixed mode)
      • Default: Enabled (recommended)
    • TCP connection is disconnected if there is no response to the ‘keep-alive’ packet. (Socket close / disconnect)
    • The ‘keep-alive’ packet is sent after the Ethernet packet is sent at least once from WIZ750SR.

  • Send Keep-Alive Interval

    • Range: 0 ~ 65535, Unit: milliseconds(ms)
      • Default: 7000, 5000 (recommended, 7 seconds / 5 seconds)
    • The required interval for sending the ‘keep alive’ packet is as below.
      • The time until the first ‘keep-alive’ packet is sent
      • The time interval between each ‘keep-alive’ packets

  • This option is recommended in case of a physical disconnection with the remote device.

    • This options is recommended especially in TCP server mode.
