@dc42 No, this is exactly the pyrometer we need. Then I'll probably have to implement the solution with the ADC board and the thermistor first.

Maybe I can connect an arduino to the 6HC via spi and then communicate with the pyrometer via the arduino?

@dc42 Thank you for your answer. The command list can be found from p.33 in the instructions from the link above. Unfortunately I did not understand whether it is Modbus ASCII or Modbus RTU. Unfortunately, the seller could not answer this question. Perhaps you have an idea.

The daughterboard should then be more accurate?

Hello,
I want to connect a pyrometer to a Duet3D6HC. According to the data sheet, the pyrometer (https ://kleiberinfrared.com/images/stories/pdf/data/Anleitungen/Manual_660.pdf) has an RS485 interface and an analogue output (0/4-20mA). What would be the best way to connect the pyrometer? Unfortunately, I cannot find out from the operating instructions whether it is a Modbus RTU or Modbus ASCII interface.

Perhaps someone can help me with the best way to connect it.

@dc42 Is there already a solution to the problem?
