  • Page 25: Analog Input Signal Connection

    Analog Input Signal Connection The PCI-9113A provides 32 single-ended or 16 different analog input signals which can be converted to digital value by the A/D converter. To avoid ground loops and get more accurate measurement of A/D conversion, it is quite important to understand the signal source type. The single-ended mode has only one input relative to ground and is suitable for connecting with the floating signal source.

  • Page 26: Daughter Board Connection

    Daughter Board Connection The PCI-9113A can be connected with several different daughter boards, including ACLD-9881, ACLD-9137 and ACLD-9188. The functionality and connections are specified as follows. 3.3.1 Connect with ACLD-9881 The ACLD-9881 has a 37-pin D-sub connector, which can connect with PCI-9113A through 37-pin assemble cable.

  • Page 27: Chapter 4 Registers Format

    Registers Format The detailed descriptions of the registers format are specified in this chapter. This information is quite useful for the programmers who wish to handle the card by low-level programming. However, we suggest user have to understand more about the PCI interface then start any low-level programming.

There is one 32 bits register on PCI-9113A. The 32 bits register occupied base address #2. The base address is allocated by PCI BIOS and is stored at offset 1Ch of PCR.

    Operation Theorem The operation theorem of the functions on PCI-9113A card is described in this chapter. The operation theorem can help you to understand how to manipulate or to program the PCI-9113A. A/D Conversion Before programming the PCI-9113A to perform the A/D conversion, you should understand the following issues: A/D conversion procedure A/D signal source control...

  • Page 34: A/D Conversion Procedure

    5.1.1 A/D Conversion Procedure For using the A/D converter, users must know about the property of the signal to be measured at first. The users can decide which channels to be used and connect the signals to the PCI-9113A. Refer to the chapter 3 ‘Signal Connection’.

  • Page 37: A/D Trigger Source Control

    5.1.3 A/D Trigger Source Control The A/D conversion is started by a trigger source, and then the A/D converter will start to convert the signal to a digital value. In PCI-9113A, two internal sources can be selected: the software trigger or the timer pacer trigger.
  • Page 38 The data must be transferred to host memory after the date is ready and before the FIFO is full. On the PCI-9113A, many data transfer modes can be used. The different transfer modes are specified as follows: Software Data Polling The software data polling is the easiest way to transfer A/D data.
  • Page 39 reading data. To avoid this problem, the half-full polling method is used. If the A/D trigger rate is 100KHz, the FIFO will be half-full (512 words) in 5.12 ms. If the user‘s software checks the FIFO half full signal every 5 ms and the FIFO is not half-full, the software does not read data.
  • Page 40 Under this mode, an interrupt signal is generated when FIFO becomes half-full. It means there are 512 words data in the FIFO already. The ISR can read a block of data every interrupt occurring. This method is very convenient to read A/D in size of a “block” (512 words) and it is benefit for software programming.

  • Page 41: A/D Data Format

    5.1.5 A/D Data Format The range of A/D data read from the FIFO port is from 0 to 4095. As the A/D gain is 1, the A/D signal range is roughly -10V ~ +10V or -5V~+5V (bi-polar) and 0V~+10V (uni-polar). The relationship between the voltage and the value is shown in the following table: Voltage (Volts) A/D Data (Hex)

  • Page 42: Interrupt Control

    2’s Complement Coding: Bipolar 10V Voltage = ( AD_Data * 20 ) / ( 4096 * gain ) Bipolar 5V Voltage = ( AD_Data * 10 ) / ( 4096 * gain ) Unipolar +10V: Voltage = ( AD_Data * 10 ) / ( 4096 * gain ) + (5 / gain) where the gain is 1,10,100.

    5. Set the analog gain = 1 and channel number #0 by software. 6. Short the A/D channel 0 (pin 1 of CN1) to ground (GND). 7. Adjust VR3 to obtain reading between 2047~2048. 8. Applied a +10V reference input signal to A/D channel 0 (pin 1 of CN1), and trim the VR2 to obtain reading between 4094~4095.
