  • Page 56 Operation Theory The operation theory of the functions on PCI-9112 card is described in this chapter. The functions include the A/D conver- sion, D/A conversion, Digital I/O and counter / timer. The operation theory can help you to understand how to configure or to program the PCI-9112.
  • Page 57 more than two floating sources are available, the source must be with common ground. Figure 4-1: Floating source and single-ended Differential input mode The differential input mode provides two inputs that respond to dif- ferences in signals. If the signal source has one side connected to local ground, the differential mode can be used to reduce the effect of ground loops.
  • Page 58 A differential mode must be used when the signal source is differ- ential. A differential source means that the ends of the signal are not grounded. To avoid the danger of high voltages between the local ground of the signal and the ground of the PC system, a shorted ground path must be connected.
  • Page 59 is cleared and indicates that the data is not ready. After the con- version is completed, the DRDY bit will return to active high (1) level. The converted data can now be read from the A/D data reg- isters. Please refer to section 3.5 for more information about the A/ D status register.
  • Page 60 fer. It's recommended that this mode be used if your application needs a fixed and precise A/D sampling rate. External Trigger Through pin-17 of CN3 (ExtTrig), the A/D conversion can also be performed when a rising edge of an external signal is present. The conversion rate of this mode is more flexible than the previous two modes, because the user can control the external signal with the external device.
  • Page 61 When the interrupt transfer is used, the hardware interrupt will be inserted and its corresponding ISR (Interrupt Service Routine) will be invoked and executed after A/D conversion is completed (the converted data is transferred by the ISR program). In PCI design, the IRQ level is assigned by the BIOS directly.

  • Page 102 Calibration In data acquisition processes, how to calibrate your measurement devices to maintain its accuracy is very important. Users can cali- brate the analog input and output channels under the users' oper- ating environment to maximize the accuracy. This chapter will guide you though how to calibrate the PCI-9112.
  • Page 103 6.3 A/D Adjustment To calibrate the analog input channel, please follow the proce- dures described below. Note that whether unipolar or bipolar input mode is applied, programmable amplifier offset should be cali- brated first. Moreover, when A/D input configuration is bipolar, you should only follow the bipolar calibration procedure.
  • Page 104 Unipolar Calibration (Gain = 1, i.e. input range = 0~+10V) 1. Set the A/D input range to bipolar 5V. 2. Adjust the voltage calibrator’s voltage output to – 4.9987V (i.e. –Vfull scale + 1/2 LSB). Apply this signal to A/D channel 0. 3.
  • Page 105 D/A Channel Calibration D/A CH1 calibration 1. Connect the DVM (+) to CN3 pin-30 (AO1) and the DVM (-) to A.GND. 2. Write the Digital value 0x0FFF into the register at BASE+10 address 3. Trim the variable resister VR3 to obtain a +5V reading on the DVM.
