Functions 

This chapter describes the different functions that can be implemented using the hardware and driver 
together.  Unless stated otherwise, the driver is assumed to be API-AIO(WDM). 

 

Analog Output Function 

This product converts digital data to analog signals according to the resolution. 

You can set a variety of conditions for analog output, including the output channel, sampling period, 

and sampling start/stop conditions. 
Analog output processes are classified as follows:
