Hi, @NewUser.
The commands of both modules are the almost same, and some commands have been added in WIZ750SR. (for example: expansion GPIO commands)
For WIZ750SR, There is no PDF file yet. you can see the user manual & datasheet on WIZwiki page.

Hello rena. Thx for the reply. There are not much information provided in the wikipage regarding the description/functioning of data pin connector ? For example pin 6 or 10 not using , therefore leave it floating ? Pin 8 got 3 function DSR/TCP connect/HW_TRIG , not much description ?
Regards.

Hi.
First, do not connect ground to pin6. If you don’t use this pin, It should connect floating.
Because, HW_TRIG is active low.
pin 10(485_sel) is RS-485 set pin. So If you don’t use RS-485 mode, It is fine to connect to ground.
Secondly, when you first insert power, MCU is check to the HW_TRIG status.
So, If you want to use HW_TRIG, You should set to active low HW_TRIG. and then set to reset or do it power on/off.
Thank you.

Hello Edward . Regarding Wiz750sr (TTL). For pin 10 , can we leave it floating also if not intend to use ? And for pin 8 , when connected to mcu io’s pin and want to send cmd to read/write , we set active low. When not in use , default is it active high ?
Regards.

Hi.
Yes. You use TTL version. Then you don’t care pin10.
in case of RS485 SEL is used to 422/485 board.
And for pin8 default have to set high.(pull-up)
Thank you
