Labview serial connection issue.

[skie]

I am trying to send and receive serial data to an X Carve controller. It is an arduino based system. I have been able to setup visa to the point where it can communicate in the test mode but it will not run in the sample program "simple serial"  I get an error that visa is not installed or missing drivers. I am using labview 2016 student edition.

I would use the LIFA (i think that the name for it) to talk with the arduino but I don't know enough about the system to rewrite the arduino programming. The xcontroller is setup up with a grbl branch tailored to the xcarve.

LIFA is outdated and has been replaced by LINX.

If you were able to get setup VISA to work with the test mode, whatever that is, then you should not be getting an error about VISA.  If you get an error about VISA is not installed or missing drivers, then apparently you do not have it installed.

What version of VISA did you install?  And did you install it after installing LabVIEW?

Installed in one package. Here is a screen shot of the current visa setup and error message.

VI used is the simple serial example.

visa version appears to be 5.8. I have 2 installed one is visa shared components the other is visa .net shared components.

Reinstall VISA.  You should have VISA 16.0 or newer in order to have compatibility with LabVIEW 2016.

reinstalled NI-VISA 17.0 - NIVISA1700full.exe

problem persists.

OK I'm looking at your screen captures.  With the VISA Test panel you send a "?" then read and get a response. There is no information shared on the COM4 configuration parameters. With the LabVIEW Simple Serial.vi Example, you show some Configuration parameters that might or might not match the serial port settings from MAX and do not get a response after sending "*IDN?"  

"?" != "*IDN?" and without a manual we cannot tell what commands the device responds to or how it expects the COM port to be set up.

Why do you think you have VISA 5.8 installed?  Your NI-MAX looks like VISA 17.0 is installed.  And I have never heard of VISA 5.8.  It doesn't exist on this chart.  http://www.ni.com/product-documentation/53413/en/

(Note: it has not been updated to include LabVIEW or VISA 17.0)

What version of LabVIEW are you running when you get the error?

Here is a side by side of MAX and the VI error. I changed to "*IDN?" to a "?" in the VI to correspond to what the USB device is looking for. I am try to get a simple message/response from the USB device. Mostly the connection will be labview sending commands and waiting for an "ok" or "error"

I think this issue might have to do with changing the device driver with "NI VISA Driver Wizard" the resulting driver is unsigned and I cannot install it.

I got 5.8 from looking threw my installed programs. I am using labview 1016 and visa 17
