switch terminal board v2 and KC868 - joyrox12 - 01-27-2021
Is it possible to use terminal switches as digital inputs?
I was not interested in that they were tied to the relay outputs, I wanted to assign them the outputs in nodered.
thanks

if your Node-Red is installed on raspberry pi. ok, no problem, let your switch terminal board connect to PI by USB port (use a usb rs232 adapter), then you can get the message that any key pressed by Node-Red.

I can send kc868 through rs232 but when I connect to the terminal switch I get no response ... what am I doing wrong?
thanks

check your pin define, use RS232's pin2,pin3,pin5, maybe you need exchange the pin2 and pin3.

He invertido el pin RX TX pero todavía no puedo leer las entradas en nodered
