Hi,
I bought a vibrating wire sensor measurement module over aliexpress. I am trying to make my own vibrating wire sensor measurement unit, to read signals from vibrating wire unit such as piezometer.
The problem is that no manual or instructions of any kind came with the package, and none are on the internet. As far as i know the circuit board came from some chinese company.
So i would realy appreciate if i could get some help with this curcuit board, for example what does the character marks on the board mean, what kind of power supply does it need etc. The only thing that is written on the package is: Model: WIN311, IN VCC: 5V, OUTPUT: RS232

You power it with 5VDC and send the information through "RS232".

You have the pins labeled on the back of the board. Its the 3rd picture from the link you gave. Please take a look before posting.

 

Ok, so i've managed to power the board with a usb cable to computer. And have connected the board with serial RS-232 connection to the computer. Now i am trying to get some kind of information from the board/microcontroller. I am using Real term serial capture terminal, but dont know what code to use to recive some sort of data about board. Does anyone know what some code or command lines to use with serial terminal connected to microcontroller? i can type some stuff in terminal but ony Transmit gets lit up, and i dont know the right commands.
