Connecting instrumentation through NI9870

[JulieStrath]

Hi

I would like to connect a spectroradiometer MS700 to my data logger (cRIO9104 - 9014 controller - NI9870 - all the ultimate versions of Labview, cRIO etc.). I know that I can run simple VIs on the NI9870 modules. The MS700 has his own software and when I try to launch it, it doesn't work (everything is properly connected).

The software is a measurement software that includes periodic measurement of the radiometer via RS-232C communication, and creates a data file (RAD file).

Does someone know how to do it? Is it possible to "call" the software?

Thanks

Julie

Hi Julie,

I assume that the drivers you have will be written for Windows with Windows being the interface to the serial port.  Unfortunately I havn't been able to find them online to confirm this so if I'm wrong do let me know.

This means that the will not be able to run on the real time target or interface with the serial module.  For this reason I believe you will have to write them yourself on the cRIO.  Hopefully some of the documentation with your instrument should tell you how to interface with it and there is a good example in the LabVIEW example finder under Hardware Input and Output>>CompactRIO>>Module Specific>>Serial that shows you how to interface with the serial module.

Let me know if you need any further help.

Hi Julie,

I hope that you solved your problem with this device. Anyway, for you and for anyone user I would like comment you that in our website you can download a free labview drivers version for this instrument.

Hi,

It is also worth mentioning with the latest version of the serial driver (NI-Serial 3.7 I believe) that you can now use the serial ports in the same way as windows through the scan engine and therefore not have to write the FPGA code yourself.
