CAN drivers must pass through MAX?

[LV]

Why is it that every time I initialize CAN communications in my CVi program,
my firewall tells me that NI MAX wants to access the internet?
Why should my app even access MAX in the first place. This apparently adde a
few seconds after starting my app and before CAN communications can
commence.

Thanks

Hi LVilla,

NI-CAN does access MAX to query about system configuration (for example: those cool virtual channels). MAX should not try to access the "Internet". However, MAX is a client/server application with many server processes running underneath. It could be that some of the things MAX does to set up interprocess communication looks to the firewall like Internet access. Which firewall are you using and what is the exact warning? If some improper access or unnecessary communication is going on, then we would like to know so we can fix it!

Hi

I am using Norton personal firewall included with Norton Systemworks 2002.05
build 53.

the message that appears is C:\...\National Instruments\MAX\NIMax.exe is
preparing to access the Internet.

Hope this is helpful
