Serial data from Matlab

Hi,

I want to send serial data from Matlab to NI 9870 and then read and save it as a text file from Labview.

So, I sent serial data to NI 9870 but I cannot receive it from labview now. There was an error when I run this code.

I attached Labview and Matlab codes.

NI 9870 and PC were connected using RS232-usb 

(NI cRIO-9022 what I have) 

Thank you!
