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:

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
