U3-HV - UART mode

Hello

I'm using U3-HV to mesure PH (PH EZO of atlas scientific) and my code is in labview.

I used AsynchSimple.VI exampel to read PH but the soft dosn't work.

i use the uart mode and tx is on FIO4 , RX is on FIO5

Please do respond ASAP! It'll be highly appreciated if anyone could help me out with it. Thank you.

Perhaps you need the mentioned MAX233 chip?
