Hi all,

 

I am new using labVIEW and I would really appreciate if you could help me with an error.

 

I am trying to control a Model LM-500 Liquid Cryogen Level Monitor (Discontinued).

 

Its drivers are available on-line and I have download them and I am trying to run the demo. 

 

When I try to run it I have the following error:

 

error code -1073807202

Old VISA Open in LM-500 Initialize.vi->LM-500 Operate.vi

 

The LM-500 is connected to my computer via serial RS232. 

 

I don't know which could be the error. I would really appreciate if you could give me any idea about it.

 

These are the drivers:

Thank you so much for your help 🙂

I think you may be missing visa runtime or something similar. Have a look at this link: http://digital.ni.com/public.nsf/allkb/1D1736BFD24A09878625742500241386

Hi,

 

I have installed a NI-VISA 5.1.2 as I am using labview 2001sp1.

 

I have also replaced old VISA open by VISA open.

 

However I am still receiving errors in VISA open. Error 1073807346 ocurred at VISA Open.

 

Possible resons: VISA: (Hex 0xbfff000e) the given session or object reference is invalid.

 

Do you know which might be the problem?

 

Thank you so much for your help 🙂

Thats because the new VISA open does not recognise the IO terminal class, you need to delete that and replace with the new type. Right click on the visa resource >> Create >> Control.

Select the rigtht COM port and try again
