Hardware configuration of WIZ105SR

I am trying to set the configuration using hardware but i am not getting the success response. I did the following:

  1. Asserted low 8th pin of J1 and got message “:”.
  2. Sent ‘>R’ and 0x0d and get the response.
  3. Sent “>W”
  4. Now send the config data with MAC address (320 bytes)
    5.send 0x0d
    I get a failure response.

Am I doing something wrong?

step4 is wrong…
Try to send the config data without MAC address.
Please refer to section “5.2.2 Changing IP Address” of user manual.
