No response in serial configuration mode WIZ107SR

It does not respond to start the serial configuration mode.
MC, VR and so on.
Send SS command, Config tool’s status is “AT mode”.
Also, send EX command, Config tool’s status is “OPEN”.
Therefore, I think that the transmission of the command has been successful.
However, it does not respond to such as MC and VR.
help me.

Hi, bashi.
The WIZ107SR’s serial commands must be entered with CRLF (Carriage return, Line feed) at serial terminal program.

Response examples of a serial command request is as follows.
This example were tested in WIZ107SR firmware version 4.05 (latest ver.)

* Serial command mode switch trigger code: 2b 2b 2b (+++) * Serial debug message enabled

Hi hkjung and thanks for the answer.

The firmware version was different. it was updated from 4.04 to 4.05.
And I tried to reproduce the example you have taught me.

====================================== GW mode

  • [Req] +++ (without CRLF)

  • [Res] LGSEG:AT Mode[CR][LF] <-- No response.
    ====================================== AT mode

  • [Req] SS[CR][LF]

  • [Res] SS2B2B2B[CR][LF] <-- No response.

  • [Req] MC[CR][LF]

  • [Res] MC00:08:DC:XX:XX:XX[CR][LF] <-- No response.

  • [Req] EX[CR][LF]

  • [Res] LGSEG:GW Mode[CR][LF] <-- No response.
    ====================================== GW mode

Switching of the mode seems to be going well.

But, no response.
Wiring I think no problem.
In GWmode, Data sent in TCP is able to receive the serial.

Ok, bashi.
I guess, the problem is may caused by serial terminal program.
We need test results more to solve this problem, please try to test again.

This test operates based on the WIZ107SR firmware version 4.05.
Note that, the mode switching messages (LGSEG:AT Mode / GW Mode) print out only when serial debug message output enabled. (configuration tool)

Thanks hkjung.

WIZ107SR firmware version 4.05.
===> OK [ATmode_.jpg]

serial debug message output enabled. (configuration tool)
===> OK [ATmode_.jpg]

HEX code, [0x53] [0x53] [0x0D] [0x0A] …
===> OK [log.jpg]

I use the “teraterm” as terminal software.
I did not know well wiznet terminal.
In GWmode, it is able to receive data sent by TCP.
For example, when I send the “abc” by TCP terminal show the “abc”.


Please use the other serial terminal program like ‘Hercules’.
hercules-setup.soft32.com/

I’ve attached simple test results.

Thanks hkjung.

I tried using the ‘Hercules’, but it was the same.
no response.
It has been able to receive in the still GW mode.
Why???
