Some basic questions about Wiz550Web



I recently ordered some units , but I’m still waiting for delivery.
I have some (stupid) questions in advance, I can not find the answers in the WIZNET docs.

Q1. Is there already a basic web server programed , so I can instantly use the module (after ETH settings) to
control IO pins ?
Q2. Do I need SD card support in case of Q1?
Q3. Is it possible to control IO pins via JSON, for example using CURL with WINDOWS?
If yes, is there a documentation about it?
If not ,is there another way to switch the pins without a client?
Q4. I have successfully compiled the WEB_BOOT and WEB_APP example with Eclipse NEON. How could I move the new
code ,after I would have modified it, on the module?
Q5. Can I connect JTAG debugger anyhow?

Would be nice if anybody could answer briefly.

Thank you very much.
