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
