voltage is seperated to BNC connector

[son]

I use BNC 2110 adaptor, AT-MIO-16E-2 and Dasylab

if I send output signal (voltage) to BNC2110 the signal seperate to two BNC connector

; if I send  5 volt to BNC 2110(AO0) I have to touch AO0(+) and AO1(+) to get the 5V and If I touch AO0(+) and AO0(-) I just get 2.5V(a half of the voltage I sent) 

I tried using another BNC2110 but that doesn't make any difference

I've also reinstalled dasylab.

Hi son,

Welcome to the forums! A couple of questions. Have you configured the reference voltages and the polarity of the analog output properly? This is explained on page 3-13 of the AT E Series User Manual.

Second, what version of the DAQ driver are you working with? Do you have Measurement and Automation Explorer on your computer, where you can run a test panel for you DAQ card and check the analog output? Measurement and Automation Explorer would  be under Programs» National Instruments» Measurement and Automation Explorer.
