MViControl Posted November 10, 2009 Report Share Posted November 10, 2009 All, I have sucessfully installed Agilent 82530B GPIB card in my system, and I enabled VISA for LabVIEW, I can operate this card in NI-MAX, but when I want to select this card, I suddenly found that the "VISA Resource name" have no pop up menu any more. before I install the GPIB card, the "VISA Resource name" can list all ports in the system. Any one have ideas about how to solve this issue? Thx in advance. Quote Link to comment
Francois Normandin Posted November 10, 2009 Report Share Posted November 10, 2009 There should be a Menu Button that you can show/hide with a right-click (select Visible Items). The drop-down list will then display all available VISA resources. (Or it could be that your VISA class is not set for Instruments.) Quote Link to comment

I think you misunderstand my point. here the problem is that I have the menu in the control, but when I click menu, there are no any item in the menu except "fresh" Quote Link to comment
Francois Normandin Posted November 11, 2009 Report Share Posted November 11, 2009 So you're not seeing at least the COM ports... Apart from VISA class, I'm sorry to say I'm at a lost of an explanation. Quote Link to comment

crelf Posted November 11, 2009 Report Share Posted November 11, 2009 here is VISA Resource name when I click the menu button: What about the port listing in MAX? Actually - I have an idea: can you please upload the VI that you're having the issues with (or, at least, a new VI with that control copied into it)? Quote Link to comment

Francois Normandin Posted November 11, 2009 Report Share Posted November 11, 2009 I have sucessfully installed Agilent 82530B GPIB card in my system, and I enabled VISA for LabVIEW... Which version of VISA drivers are you using at the moment? Have you tried to reinstall the latest drivers? (v4.6 Run Time or Full) Quote Link to comment
ooth Posted November 11, 2009 Report Share Posted November 11, 2009 Yes, I see nothing except the "fresh", but I can see & operate "serial port", "GPIB" in MAX sucessfuly. here is VISA Resource name when I click the menu button: This is just a thought. Sometimes this happens to me and it's because the GPIB card is loose in the PCI slot. Once I push it back in the VISA works. I know you said that you can communicate with MAX which would mean that the GPIB card is working, so I'm not too sure if this is your problem. Quote Link to comment
MViControl Posted November 11, 2009 Author Report Share Posted November 11, 2009 Which version of VISA drivers are you using at the moment? Have you tried to reinstall the latest drivers? (v4.6 Run Time or Full) I use NI-VISA 4.5.1, I will try to reinstall the driver, hope it works. This is just a thought.

I know you said that you can communicate with MAX which would mean that the GPIB card is working, so I'm not too sure if this is your problem. I tryed already, it do not help, I think I should try to reinstall NI-VISA. Quote Link to comment

Francois Normandin Posted November 13, 2009 Report Share Posted November 13, 2009 Doh! That makes me remember this old joke: "If your car stops working and you don't know why, try shutting down the *Windows* and opening them again before you call the garage." Quote Link to comment
