I am trying to communicate with an infrared pyrometer via its RS485 port. I use a RS485 to USB converter which opens a virtual COM port on my Windows 7 machine. I tried giving it a few commands, such as "?XU" (sensor version), but did not get a coherent reply, just a bunch of ascii codes.

Has anyone here ever worked/communicated with such a pyrometer via its communication port?

Thank you,

Amit

It sounds like you're at least able to communicate with the device but the commands we are sending might not be right. Is the "?XU" command given by the manufacturer? What is model of the pyrometer? Are you using NI MAX VISA Test panels to query the device?

I identified one problem - the RS485 to USB adapter was faulty. I will replace it with a working one and post an update here.

Sounds good! I'll continue to monitor this forum to see how things turn out.

It was indeed a faulty RS485 to USB converter.
