# W5500 SET UP DIRECTLY THROUGH ETHERNET

## Question

Asked by centurymetering on 2019-08-05 in Ethernet Chips.

Sir,
We are using W5500 in an application and are setting internet parameters like
IP setup: Static or DHCP
IP address
Netmask (submask)
port number
etc through the UART port of the support micro controller.
Can we know if the above parameters can be set directly through the ETHERNET PORT ITSELF onto the on board W5500 directly.
Regards

No, and it should not, as this will be serious security breach.

Sir,

Thanks for your immediate reply.

But in the WIZNET108SR we are able to set these parameters directly through the ethernet.

We thought, we should be able to do the same thing in our board without having to resort to another port of the supporting micro controller which after receiving the data through one of its UART ports, programs the on board W5500.

Hi, centurymetering

there are two ways to set network information by ethernet communication.

first one is you set board’ network information at the first time. Then you can connect the board via ethernet and change the information (Actually, WIZ108SR using this way)

second, by mac communication(like ARP), you can communicate the board without default network information.
All wiznet products support macraw communication. But this concept is from wiznet. So, it is hard to find examples out there and you have to make your own application for it.

I recommend you to set default ip network, and then change it through udp or tcp communication.

thank you
