VISA 5.1.1 on MAC Os 10.6

[ACarpio]

I need to connect a Mac-mini (OS-10.6.8 in Bit) with a Medical Monitor Philips MP20. I wrote the software using LabView 2009 and VISA 5.1.1. I am using a serial to USB convert port from VS-COM company.

The manual of monitor command to make first an association between the server (medical monitor) and the client (Mac mini). This operation works very well. Then, I set several parameter to the monitors and works very well. When I begin to get data from Monitor, for example Demographic data of patient, start problem like latency between the request msg from Mac mini and the response of the monitor; I get the Error -1073807339  ( I found this link to solve the problem http://digital.ni.com/public.nsf/allkb/874B379E24C0A0D686256FCF007A6EA0 , but no works).

If I run the same VI en a Mac mini with Os 10.5.8, works without any problem. But We want it to work with Os 10.6 or higher! Can you help me with this issue?

According to NI's web site VISA 5.1.1 is still in beta testing.  5.0 is listed as compatible with 10.6.8.  Can you try that?

I have VISA 5.1.0 on my computer.  I got it when I bought LV 2011 last fall, but I do not see a 5.1.0 version listed on the web site.

With all the local variables you may have a race condition in your program. This could cause the program to work on one machine and not on another.
