Set Network Name for WIZ750SR

Question

Does anyone know how to set the network name in a WIZ750SR ethernet module so it can be pinged by that name like other network devices?

Thanks for replying. Our application will be consumer based and we can't expect them to be editing the hosts files or DNS entries. Do any WIZnet ethernet products support network naming as described. I have used other (older) products from different vendors that could do it, but I am looking for a new product to align with.

Hello, There are two ways to modify the device name of WIZ750SR. The first method is through Web Server Configuration if you are using the latest firmware version (1.4.0) of WIZ750SR. You can modify the device name in this section. Please refer to the link below for more details. https://docs.wiznet.io/Product/S2E-Module/WIZ750SR/WIZ750SR_Web_Config_Guide_EN The second method is to change the firmware from the link below and upload it. You can make the changes in Projects\S2E_APP\src\W7500x_board.h file of the project. However, if you have never modified the firmware of WIZ750SR before, this can be a very complex task because it requires a paid development environment like KEIL5. If you're okay with that, you can proceed by referring to the firmware details below. https://github.com/Wiznet/WIZ750SR Hope it helps.

Hello, I'm Theo from WIZnet. If you want to change the device name on the WIZ750SR and use it properly, you need to consider the Configuration Tool and the device firmware separately. Even if you successfully added "MC55051" to the firmware, the Configuration Tool receives the string value "WIZ750SR" and assigns it to the tool's internal index based on the device. Since the tool doesn’t have any information about "MC55051" in its internal code, it cannot retrieve the device information, resulting in an error. The tool updates its values using commands sent from the S2E module, while the web page directly retrieves the information from the S2E through web server Ethernet packets. This allows the web page to display the value properly. This is the reason why the name shows correctly on the web page. Therefore, if you want to use a device name like "MC55051", code modifications are required in two main areas (the Configuration Tool and the WIZ750SR firmware). While the code modifications themselves are quite simple, the build environment (using Keil and Python) may be challenging. You need to review the code in the W7500x_board.h file of the WIZ750SR firmware to add the device. Additionally, download the Configuration Tool code from the WIZnet GitHub channel to find where the board name is added and where the selection process occurs (likely in the main.py code). Code modifications in both areas are necessary.
