Impossible to use COM port

[IngoWolf]

I found the solution for getting ComPorts and TCP/IP in MAX.

Uninstall all the NI Stuff from your non developer maschiene.

Install the MAX, DAQ and NI-VISA parts you need from the Labview Driver CDs.

Now you have VISA-IP and Serial in MAX

After that you can reinstall the more actual runtimes from the net, they shouldn't remove booth again.

Let me see if I can clear this up, because some of the information listed in this post isn't 100% correct.  First of all you CAN download both the full and run-time versions of NI-VISA on the web.

NI-VISA 4.3 Full
http://joule.ni.com/nidu/cds/view/p/id/988/lang/en

NI-VISA 4.3 Runtime
http://joule.ni.com/nidu/cds/view/p/id/989/lang/en

Here are the differences.

• The runtime does not include MAX or MAX support.  Even if you have MAX installed by some other NI driver, you won't see any VISA resources, because the VISA MAX provider is not included with the runtime.
• The runtime doesn't automatically alias devices.  This is something that the VISA MAX provider handles when it finds a new VISA resource for the first time.
• The runtime will not work with the Development version of LabVIEW.
• You can not build any C/C++/.NET or any other application with just the runtime engine installed because it doesn't include any development library support.
  

• The runtime was designed as a very light weight version of NI-VISA which only includes the binaries to allow customers to deploy compiled executables that either already know the resource name or had a built in way to find the resources need for the application.  See examples on programmatically finding visa resources using VISA Find.
  
• We do support the ability to include a visaconf.ini file with the runtime to allow you to distribute aliases with your application.  See KBs on visaconf.ini.
  

If your application requires the user to go into MAX to find the correct VISA resource (COM,TCP, USB, what ever) and/or configure it then it will need to be used with the full version of NI-VISA.  Note that NI is the only VISA vendor that supplies a VISA runtime.  The full version of NI-VISA is the equivelent to any other vendors VISA.

Please let me know if any of this is unclear.
