This chapter includes an overview of the PC-LPM-16PnP board and 
explains the operation of each functional unit making up the board. This 
chapter also explains the basic operation of the PC-LPM-16PnP 
circuitry.
 
Functional Overview
 
The following are the major components making up the 
PC-LPM-16PnP:  
• PC I/O channel interface circuitry
• Analog input and data acquisition circuitry
• Digital I/O circuitry
• Timing I/O circuitry
You can execute data acquisition functions by using the analog input 
circuitry and some of the timing I/O circuitry. The internal data and 
control buses interconnect the components. The theory of operation for 
each of these components is explained in the remainder of this chapter.
