Serial port i.e UART (Tx, Rx) connections documentation

  1. I can not able to connect ncd board with serial port i.e UART (Tx, Rx) connections.

  2. i want to read analog pins data via serially, what are the codes/bytes to send serially to board so that we can get proper response for analog reading.

I am unable to find documentation for this.


Could you post a photo of the controller you are working with? We sell several models with Serial interface.

Thank you,

That appears to be an RS 485 module.

If you only need RS 232 then you will want this module:

Let me know if you need support for the RS 485 module.
