After installing NI Scope 3.5 RS232 in my application is very slow!

[ryszard]

I am using NI5114 Digitizer. After installing NI Scope 3.5 RS232 in my application is very slow. Un-installing Scope driver doesn’t help. Serial communication from my application (developed in CVI) is permanently crippled. The only fix is re-installing Windows. It happened on three different computers. I am stuck with this problem. Please help

 Hi Richard,

 I'm very curious about where you received your NI-Scope v3.5 from, the latest version currently available is v3.4, this can be found here.

 NI-Scope does install NI-VISA, which will affect your serial ports in Labview.

 What version of NI-Scope does MAX show?
 What version of NI-Visa does MAX show?

 You could try un-installing both of those drivers then re-installing the NI-Scope v3.4 driver.

 Please do post back the results of checking the version installed of NI-Scope and NI-Visa.

 Best regards,
