Problems about Mac OX 10.6 V.S. Windows XP SP3

[LITE]

Hi all

I have a problem with my MacBook Pro.

My system is Mac OX 10.6, but I use BootCamp of 10.6 to set up the Windows XP SP3 on the same laptop. Then I set up LabVIEW 8.5.1 on Windows XP system, and use Agilent 823578 USB/GPIB Interfaces to communicate with SR830 Locking Amplifier.

When operating Angilent Connection Expert, I could communicate with SR830 through Agilent 823578 USB/GPIB Interfaces. However I could not use relative command of VISA in LabVIEW, such as VISA Open, to communicate with SR830.

On the other hand, I use the same program on the Windows-based DELL PC to communicate with SR830 without any problem.

So I was wondering is there any problem about compatibility of MacBook Pro and Mac OX 10.6 with Instrument Driver ?

I will be appreciated if anyone could help me solve my problem. Thank you all.

Doubtful there can be anything wrong with an instrument driver. The VISA Resource is obtained from the visconf.ini file and in order for MAX to populate that, you need to enable tulip support when you use a non-NI controller. You must have done that on the windows pc.

Hi Dennis

Thanks for your help. I was wondering if you could teach me how to set up the correct visconf. ini file, and where is the visconf.ini folder. Thank you.

First, you need to enable tulip support so that MAX recognizes the agilent controller. In MAX, you select NI-VISA under the software listing. Click on the VISA Options tab and then under MySystems>General Settings, select Passports. Check the box for NiVisaTulip.dll. If you do a View>Refresh, the controller should then be listed though you might have to reboot. When MAX lists the agilent controller, you should be able to scan for instruments. This is what will update the visaconf.ini file.

I'm sort of going by memory on this and have only done this on windows pc's. I really don't know if there are any problems with running it under a VM on the Mac. There are numerous links on the boards related to using agilent controllers with LabVIEW so you might want to do a search to see if I have missed any details.

It works. Thank you very much.
