Control for Optris CSmicro Infrared Thermometer (USB interface)

[M_HUI]

I am developing one “Start” button to control Optris CSmicro Infrared Thermometer, instead of the designated “Run” Button. So, I apply an event structure in a while loop to control Optris CSmicro Infrared ThermometerCSmicro LT15 (OPTCSMALT02SF0505K).  In the Visa Configure Serial Port, the stop bit is tuned to 1. When I run the program, the following error message is obtained in the attached file, “Error – 1073807330 occurred at property node in Visa Configure Serial Port.” As the stop bit is tuned to 10, then the waveform chart shows the temperature. Is it correct to tune the stop bit equal to 10 in the Visa Configure Serial Port for this Infrared Thermometer?

However, when I press the “IR Theremometer” button, the waveform chart always get a burst initially in the attached figure. (It seems that the initial burst is related with the start button.)How can I prevent the initial burst? 

Thank you for your suggestion in advance.

The valid inputs for the Stop Bits are: {10, 15, 20}.  When you enter {1}, you get an invalid response which is to be expected plus when you set it for {10}, it functions properly.

If you RMB (Right Mouse Button) on the stop bits Input and request a Control you will see the three options.  Now RMB on the new control and request 'Edit Items' to see how the entries work.

BTW: Not all Stop Bit settings may work with your device.
