  • Page 36: Chapter 4 Operation Theorem

    O p e r a t i o n T h e o r e m The operation theorem of the functions on PCI-9112 card is described in this chapter. 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-9112.
  • Page 37 Single-ended Mode The single-ended mode has only one input relative to ground and it suitable for connecting with the floating signal source. The floating source means it does not have any connection to ground. Figure 3.4 shows the single-ended connection. Note that when more than two floating sources are connected, the sources must be with common ground.
  • Page 38 A differential mode must be used when the signal source is differential. A differential source means the ends of the signal are not grounded. To avoid the danger of high voltage between the local ground of signal and the ground of the PC system, a shorted ground path must be connected. Figure 3.6 shows the connection of differential source.

  • Page 39: A/D Conversion Procedure

    4.2.1 A/D Conversion Procedure The A/D conversion is starting by a trigger source, then the A/D converter will start to convert the signal to a digital value. The PCI-9112 provides three trigger modes, s ee section 5.1.2. While A/D conversion, the DRDY bit in A/D status register is cleared to indicate the data is not ready.

  • Page 40: A/D Data Transfer Modes

    External Trigger Through the pin-17 of CN3 ( ExtTrig), the A/D conversion also can be performed when a rising edge of external signal is occurred. The conversion rate of this mode is more flexible than the previous two modes, because the users can handle the external signal by outside device. The external trigger can combine with the DMA transfer, interrupt data transfer, or even program polling data transfer.

  • Page 41: D/A Conversion

    DMA Transfer (DMAX) The DMA (Direct Memory Access) bus master allows data to be transferred directly between the PCI-9112 and the PC memory at the fastest possible rate, without using any CPU time. The A/D data will be queue at local FIFO on the PCI-9112 itself and it is automatically transferred to PC's memory.

  • Page 42: Digital Input And Output

    Digital Input and Output The PCI-9112 provides 16 digital input and 16 digital output channels through the connector CN1 and CN2 on board. The digital I/O signal are fully TTL/DTL compatible. The detailed digital I/O signal are specified in section 1.3. To program digital I/O operation is fairly straight forward.

  • Page 43: Timer/Counter Operation

    Timer/Counter Operation The PCI-9112 has an interval timer/counter 8254 on board. It offers 3 independent 16-bit programmable down counters; counter 1 and counter 2 are cascaded together for A/D timer pacer trigger of A/D conversion, and counter 0 is free for your applications. Figure 3.10 shows the 8254 timer/counter connection.

    C a l i b r a t i o n In data acquisition process, how to calibrate your measurement devices to maintain its accuracy is very important. Users can calibrate the analog input and analog output channels under the users' operating environment for optimizing the accuracy.

  • Page 76: Vr Assignment

    VR Assignment There are five variable resistors (VR) on the PCI-9112 board to allow you making accurate adjustment on A/D and D/A channels. The function of each VR is specified as Table 6.1. A/D bipolar offset adjustment A/D full scale adjustment D/A channel 1 full scale adjustment D/A channel 2 full scale adjustment A/D unipolar offset adjustment...

  • Page 77: D/A Adjustment

    D/A Adjustment There are two steps to calibrate the analog output channels, D/A 1 and D/A 2. The first step is to adjust the reference voltage, and the second step is to adjust each channel of D/A. 6.4.1 Reference Voltage Calibration Set reference voltage as -5V (the D/A reference voltage is selected by JP3, see section 2.8).
