Problem with array and rs232

[sarah83]

Hi!

I should test different channels with rs232.

I have an array in which I can choose my rx and tx ports.
If I write a value in my stingfield, click on start, I only get the values in my first array field of the choosen rx and tx.

What could be the problem?


vi is 7.1.1

Hmmm, I have problems to attache something :-s

Actually, your serial code seems to work fine, since you're getting data, so there's probably a problem in the way you build the data to be sent, but there's no way to really be able to tell without your code. Make sure you don't preview your post before attaching, or you lose the attachment.

I can't run your code and I'm not entirely sure what your problem is, but if I understand your code correctly, the values are sent from all of the write ports to just the first read port. This is becuase the Index Array VI takes only the first VISA reference from the array. If this is your problem, you should enable indexing on the other array as well and get rid of the index array VI. Keep in mind that the arrays should be the same size. If they're not, you'll need another for loop inside the one you have, and you should index one of the arrays through that one.
Also, your code is hard to read. Try to avoid overlapping structures and wires and don't use a property node to read or write a value. The preferable way is to use a wire and if you can't, use a local variable. I suggest you search the site for "style guide". It should have some tips for good programming techniques.
If this didn't help, feel free to elaborate more on your problem.

Maybe you must cut out the Arinc and Synchro parts. This could be the reason why it won't run.

Hmm, I thougt I have done this indexing in the "test" case. The index values are everytime 12.
But the number of testing ports can switch between 12, 3 and 4 (option field on the left).

I'm sorry for the hard readable code, it is my first vi and I never worked with lv before.
Thanks for the style guide information!
