22 • Operation Theorem 4 Operation Theorem The operation theorem of the functions on PCI - 9111 card is described in this chap ter. The functions include the A/D conversion, D/A conversion, Digital I/O and counter / timer. The operation theorem can help you to understand how to manipulate or to program the PCI - 9111.
Operation Theorem • 23 RA n 0 Ohm To Multiplexer Analog Input Channel #n RB n OPEN CA n OPEN 4.1.1 A/D Conversion Procedure For using the A/D converter, users must know about the property of the signal t o be measured at first. The users can decide which channels to be used and connect the signals to the PCI - 9111.
24 • Operation Theorem Analog Input Signal Connection The PCI - 9111 provides 16 single - ended analog input channels. The analog signal can be converted to digital value by the A/D converter. To avoid ground loops and get more accurate measurem ent of A/D value, it is quite important to understand the signal source type.
Operation Theorem • 25 Signal Range The proper signal rang e is important for data acquisition. The input signal may be saturated if the A/D gain is too large. Sometimes, the resolution may be not enough if the signal is small. The maximum A/D signal range of PCI - 9111 is +/ - 10 volts when the A/D gain value is 1.
26 • Operation Theorem refer to section 4.6 for timer/counter operation. This mode is ideal for high speed A/D conversion. It can be combined with the FIF O half full interrupt or EOC interrupt to transfer data. It is also possible to use software FIFO polling to transfer data.
Operation Theorem • 27 It is possible to read A/D converted data without polling. The A/D conversion time will not exceed 8.5 µ s on PCI - 9111 card. Hence, after software trigger, the software can wait for a t least 8.5 µ s then read the A/D register without polling.
28 • Operation Theorem EOC Interrupt Transfer The PCI - 9111 provides traditional hardware end - of - conversion (EOC) interrupt capability. Under this mode, an interrupt signal is generated when the A/D conversion is ended and the data is ready to be read in the FIFO.
Operation Theorem • 29 software must continuously read data out from the FIFO to prevent FIFO full. The software also should poll the counter value to check if the A/D sampling is stopped. To set up the Pre - Trigger mode, the following steps should be followed: 1.
30 • Operation Theorem 4.1.6 A/D Data Format The A/D data read from the FIFO is in the two ‘ s complement format. As the A/D gain is 1, the A/D signal range is roughly +10V ~ - 10V bi - polar. In PCI - 9111HR, the whole 16 bits A/D data are available.
Operation Theorem • 31 4.2 Interrupt Control 4.2.1 System Architecture The PCI - 9111‘s interrupt system is a powerful and flexible system which is suitable for A/D data acquisition a nd many applications.
32 • Operation Theorem users must check if another IRQ is also asserted, then clear current IRQ to allow the next IRQ occurring. The two IRQs are named as INT1 and INT2. INT1 comes from AD EOC or the FIFO half - full flag. INT2 comes from timer‘s pacer output or the external interrupt request.
Operation Theorem • 33 4.4 D/A Conversion The PCI - 9111 has one analog output channel. The signal range can be uni - pol ar or bi - polar which are set by JP1. To D/A Output D/A Converter - + - 10V Ref In Analog GND Pin - 30 (DA Out) The operation of D/A conversion is simpler than A/D operation.
34 • Operation Theorem 4.5 Digital Input and Output To program digital I/O operation is fairly straightforward. The digital input operation is just to read data from the corresponding registers, and the digital output operation is to write data to the corresponding registers.
Operation Theorem • 35 4.6.2 Pacer Trigger Source The timer #1 and timer #2 are casca ded together to generate the timer pacer trigger of A/D conversion. The frequency of the pacer trigger is software controllable. The maximum pacer signal rate is 2MHz/4=500K which excess the maximum A/D conversion rate of the PCI - 9111.
