I'm trying to read the temperature sensor (Pt1000) value from Node-RED.

Connection: The Pt1000 sensor is connected to a digital converter, which converts the readings into digital values. The converter is connected to the RS485 socket of the Revolution Pi (running Raspbian OS). I tried to read the value on NodeRED but encountered an error.

Hello Ajinkya09, thank you for your detailed description of the error. Please send me an SOS report.

Hi Ajinkya09, now we remembered one more thing, you are using /dev/ttyAMA0 - this is the UART that is connected to the PiBrige. So that can't work. With RevPi Connect (+)/S/SE the correct UART is /dev/ttyUSB0
