Accelerometer Set-up in DAQ USB-6210: not getting changes in value

Hello, 

I have been trying to set-up my accelerometer with USB-6210 and haven't been getting changes in output as I moved the accelerometer.

This is the 2-axis accelerometer I've been using: http://uk.rs-online.com/web/p/accelerometer-ics/8197275/?searchTerm=AD22037Z&relevancy-data=636F3D3226696E3D4931384E4B6E6F776E41734D504E266C753D656E266D6D3D6D61746368616C6C7061727469616C26706D3D5E5B5C707B4C7D5C707B4E647D2D2C2F255C2E5D2B2426706F3D313326736E3D592673743D4D414E5F504152545F4E554D4245522677633D424F5448267573743D414432323033375A26&sra=p

The accelerometer is supplied 5V directly from the DAQ and has 2 signal outputs (2-axis) to ports AI8 and AI1, differentiating wiht respect to AI1, in the attached set-up

I have been getting an output of approximately 4.9V and this does not change when there is a physical change in motion. Could anyone guide me into the right direction? I'd appreciate that

Thanks,
