Problem in reading signal at DIO of myrio 1900

Hello,

I am controlling myrio from keyboard (PC)
I am using network-published shared variable to share data from Host VI (k.vi) to target VI (k_myrio.vi)

when I press RIGHT arrow key on keyboard , DIO 21 and DIO 25 should give me 3.3 V (when measured by DMM) but this is not happening, I am getting 1.65 V  Why is this happening?
same in case of LEFT arrow key 
if I add more variable then I am getting less than 1.65 v i.e. 0.75 v 
 

I have attached both vi 
vi computer as a target = k.vi

vi myrio as a target = k_myrio.vi

 and Keyboard is project 

Please provide me solution asap
