       We need install the drive of the motion-card before we use the adt8940A1-card.Otherwise,we cann't use the functions of  the motion-card.we can use the return of the function of "adt8940A1_initial" to judge if the drive has been installed  successfully.	If the return is less than zero,the service of motion-card hasn't started-up. 

      Install Steps:

	(1)Copy the dynamic link library "adt8840.dll" to the system directory or the current directory ;
	(2)Ethernet connected device through a direct call to the dynamic link library "adt8840.dll";
