Hi GerdW,

                  First of all thanks for your response. I have attached my VIs for image file. You will see at transmitter side if i send frame of 160 in each iteration, receiver process each frame separately but i need whole data at once at the receiver to get image back. second option is to send whole data simultaneously instead of frames of 160 but 5640 card is unable to process all the data simultaneously. Now plz advise me what should i do to solve this issue. I will be waiting for ur response....

            Best regards

Hi Zaib,

to convert arrays is pretty basic, maybe you should also attend here!

1d to 2d: use a "build array" node (or use auto-indexing on the output of a FOR loop)

2d to 1d: this depends on your goal. you may use "index array" to get a row or column from the 2d array. you can use "reshape array" to do reshaping. you may use auto-indexing on the input of a FOR loop. As said above, this depends on your goals...

For your vis:

Sorry, I can't access them from home as I only have LV7.1 available at the moment...
