[mfranci]

I use the DAQ516  with a program derived from  samples\easyio\ailog.c and ai_asyn.c with input single-ended :

In what way I can use the differential input ? What code i must to put ?

I use DAQ Card 516 , CVI 6.0 and Windows XP .

Many Thanks .

Hi,

The board you are using is only programmable using NI-DAQ Version 6.9.3. The device configuration is done through the Measurement & Automation Explorer (MAX). Under Devices and Interfaces you should see the Device listed. Right click on it and select "Properties...". You will get a popup screen with different Tabs

- General> You can configure the device number and test resources for the device

- Analog Input (AI) > you will be able to configure AI mode (Differential or Single Ended) and the polarity if available.

After the config is done, apply your differential signal to one of the 4 Diff channels that are represented by the couples: 0,4 1,5 2,6 3,7.

This should take care of your problem.
