Configuration Tool Details

1. Icon Menu

Figure: Menu Icons

1) Device Search

Searches for WIZ750SR on the same network.
Search can be done via UDP Broadcast³⁾ or TCP Unicast⁴⁾

Use TCP/UDP port 50001 to search WIZ750SR. Search can be unsuccessful due to firewall or virus protection software.
- In this case, try to search after turning off the firewall or virus protection software.
- Please refer to this guide if still unsuccessful.
  - Troubleshooting Guide: Device cannot be searched

2) Apply 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.
- In this case, try to upload after turning off the firewall or virus protection software.
- Please refer to this guide if still unsuccessful.
  - Troubleshooting Guide: Firmware cannot be uploaded
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

4) Reset Device

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) Save Config

Saves current device's settings to a file.
When the environment changes or you want to apply the current device settings to another device.

7) Load Config

Load the settings of the file saved with Save Config.
After loading the settings, press the Apply Settings button to apply the device.

8) Exit

Ends the configuration tool.

List of devices searched will appears.
- Searched results shows the number of devices searched.
- Each device is identified by its MAC address and device name.

4. Search Method

Search ID code

This section is for inputting code when the search identification code is set.
If this option is selected, the assigned code must be entered when searching devices.

Search method

Search can be done via UDP Broadcast⁵⁾ or TCP Unicast⁶⁾

5. Status bar

Shows the result of the search.
- MAC addresses will be shown together if multiple devices are searched.
The progress bar is shown during firmware updates.

6-2. Basic settings Tab

Figure: Basic settings Tab

Shows the current firmware version⁷⁾
Composed of three sections: Major version number, Minor version number, and Maintenance version number ex) v1.0.0

2) Search identification code

Range: Up to 8-bytes string
- Default: Null (Not used)
The search identification code is for identifying the device search⁸⁾.
If this option is selected, the assigned code must be entered when searching devices.

3) Network configuration

Static (default)
- By selecting this option, users can enter the IP address, subnet mask, gateway address, DNS server.

DHCP
- By selecting this option, all information is automatically allocated from the router (DHCP server).

* Details of IP address allocation are available at WIZ750SR User's Manual: IP address settings.
* PPPoE mode is not supported.

6-2. Options Tab

Figure: Option Tab

1) TCP Timeout

TCP retransmission retry count setting
Value: 1~255

2) Status pin

Set status I/O pin S0(PA_10) and S1(PA_01) operation mode

3) Serial debug

Enable debug message output
- By enabling this option, the product information or error status can be printed via the Debug UART.
- The serial settings of the Debug UART is fixed as 115200-8-N-1:None.
- User can monitor S2E(Serial to Ethernet) or E2S(Ethernet to Serial) data when the Enable with Data option is set. (Available since WIZ750SR v1.2.2 or later)

4) Serial command mode

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.

Please take caution of the following when using Trigger code.

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.
The time interval for each byte of the 3-byte command mode switch code has to be at most 500ms.
Do not end the command mode switch code⁹⁾ with CR¹⁰⁾ or LF¹¹⁾.
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) Connection password (TCP server mode only)

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

5) Serial data packing condition

WIZ750SR provides multiple serial data packing options¹⁵⁾. 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 does 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 does not operate if set to '0x00'.

6) Timer interval

Inactivity Timer
- 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.

Reconnection Interval
- 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.

7) TCP Keep-alive interval

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.
  - Initial interval: The time until the first ‘keep-alive’ packet is sent
  - Retry interval: The time interval between each ‘keep-alive’ packets
