4. Programming  Guide 

 
The PCI730 is supplied with a complete software development kit. EDR Enhanced (EDRE 
SDK) comes with drivers for many operating systems and a common application program 
interface (API). The API also serves as a hardware abstraction layer (HAL) between the 
control application and the hardware. The EDRE API makes it possible to write an application 
that can be used on all hardware with common sub-systems.  
 

EDR Enhanced API 

The EDR Enhanced SDK comes with both ActiveX controls and a Windows DLL API. 
Examples are provided in many different languages and serve as tutorials. EDRE is also 
supplied with a software manual and user’s guide. 
 
The EDRE API hides the complexity of the hardware and makes it really easy to program the 
PCI730.  It has got functions for each basic sub-system and is real easy to learn.
