Labview version of RS232

[YY2022]

If I want to use the NI USB-232/2 in the Labview 2012. That means there are two input: Com3 and Com4. And every Com input has 8 channels input signal. So If I want to get the signal of Com3 (8 channel) and Com4(8 channel)  at the same time, whether the output can has a 16 channels signal in the Labview 2012?

I can make sure that in the Version of Labview 2008. I can get the 16 channels signal.

1)So why I can not get 16 channels signal in the Version of Labview 2012?

2)I want to know that whether it is because I use the different Version of Labview, NI MAX or the VISA? Whether the version of Labview, NI MAX or the VISA make I always get a Com is okay in the NI MAX? 

3) What is that mean in the picture: IS port connected: VI_FALSE?

Thanks

Hi YY,

please stop creating new threads for the very same problem! I merged them…

And please stop attaching huge photographs of computer screens. There are better ways to create screenshots or to attach (real) code…

1. Didn't we discuss that before?
2. We don't know. It really would help when you would start to debug and to present some real error codes…
3. This is (most probably) not relevant for your problem. See item 2.

I believe that there is no issue with RS232 or LabVIEW but rather your understanding how drivers and LabVIEW work.

Please elaborate what do you meant by 8 channel connected to RS232? do you have some serial device that has 8 channels?? if so what is the device?
