Why the RS232/485 ports of my sbRIO-9636 do not appear in my project?

[dfousek]

Hi !

I want to access the RS232 and 485 ports and they do not appear in the list of the selectable inputs. Is there a way to use them in a Real-Time project? Better, how can I use them from an FPGA VI?

Regards,

Dimitri

Well, I discovered that the Evaluation Board's software did not include the VISA related components, therefore by selecting them, I can see now the 3 ports.

The 2nd part of my question remains (whether I can use them in FPGA VIs), but I am afraid that the answer wil be: No

Hi Dimitri,

These ports are accessed as resources COM1-3 (see manual) and are programmed with the VISA functions to read and write from LabVIEW RT applications. Glad to see you found that!

So far as the FPGA VI, you can adapt some of your FPGA DIO lines to communicate with such devices, but not through the supplied COM ports, those are accessed through RT only. Here's a handy tutorial discussing the options.

Hope this helps!

Hi Dimitri,

           I am facing the same problem. How do you include the VISA related compenents? I would appreciate if you could share, thank you.

Hi Zahari,

Please see the links I referenced above and let us know if there are any follow-up implementation questions.

Thanks!
