    Installation This chapter describes how to install the PCI-9111. At first, the contents in the package and unpacking information that you should be careful are described. The PCI-9111 does an automatic configuration of the IRQ, port address, and BIOS address. Therefore, it is not necessary to set the above configurations as you use ISA DAS card.

  • Page 25 3. Trouble shooting If your system will not boot or if you experience erratic operation with your PCI board in place, it’s likely caused by an interrupt conflict (perhaps because you incorrectly described the ISA setup). In general, the solution, once you determine it is not a simple oversight, is to consult the BIOS documents that come with your system.

Usually, only the 4 LSBs are used and 16 input channels can be selected. However, if there is an extension board which can provide extension ability to 256 analog input channels, the 4 MSBs (CN4~CN7) can also be used to control the extension board.

Please refer to chapter 6 for more detailed information. 4.17 Low-Level Programming To operate the PCI-9111, users do not need to understand how to write a hardware dependent low-level program. The control of the PCI controller is complex and not described in the manual. We do not recommend users to program its applications based on low- level programming.

  • Page 46: Operation Theorem

    Operation Theorem The operation theorem of the functions on PCI-9111 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-9111.

  • Page 47: 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-9111. Refer to the chapter 3 ‘Signal Connection’. In addition, users should define and control the A/D signal sources, including the A/D channel, A/D gain, and A/D signal types.

  • Page 48: A/D Signal Source Control

    Signal Type & Signal Conditioning The A/D signal sources of PCI-9111 could be single ended (SE) only. Three are 16 SE A/D channels on board. The R/C filters (attentuators) are on board for every channel. The RC circuits for each channel is shown in the following diagram, where ‘n’...

  • Page 49: A/D Trigger Source Control

    The current A/D channel number could be read back from the A/D data register on 12 bits PCI-9111 DG but it is not possible to be read back for PCI-9111HR. Note that the MUX register is 8 bits. The 4 LSBs is used to select the multiplxer on board.
  • Page 50 The A/D operation mode is controlled by A/D mode bits (EITS, TPST) of A/D mode register. Total three trigger sources are provided in the PCI-9111. The different trigger conditions are specified as follows: Software trigger (EITS=0, TPST=0) The trigger source is software controllable in this mode.

  • Page 51: A/D Data Transfer Modes

    A/D Data Transfer Modes The A/D data are buffered in the FIFO memory. The FIFO size on PCI-9111 is 1024 (1K) words. If the sampling rate is 100 KHz, the FIFO can buffer 10.24 ms analog signal. After the FIFO is full, the lasting coming data will be lost.
  • Page 52 The data polling transferring is very suitable for the application need to process AD data in real time. Especially when combining with the timer interrupt generation, the timer interrupt service routine can use the data polling method to get multi-channel A/D data in real time and under fixed data sampling rate.

  • Page 53: Pre-Trigger Control

    The FIFO half-full polling method is the most powerful A/D data transfer mode. 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.
  • Page 54 After the external pre-trigger signal is inserted, the 8254 counter 0 is started to count number of the A/D conversion trigger signal. After set up the pre-trigger mode, the hardware is continuously acquiring A/D data and waiting for the PreTrig signal. Before the Pre-Trigger is inserted, the software must read the FIFO data to prevent the FIFO full.

  • Page 55: A/D Data Format

    The Pre-trigger timing is shown as following: Set pre-trigger mode External Pre-trigger Event A/D Stop Counter # 0 counting from N down to 0 Time Aquire Infinite A/D Aquire N A/D data after databefore Pre-trigger Pre-trigger If the application acquires data after the pre-trigger, only the last N data is need to be stored.

  • Page 56: Interrupt Control

    The A/D data of 12 bits PCI-9111 is on the 12 MSBs of the A/D data. The 4 LSB of the 16 bits A/D data are the channel number and must be truncated by software. The relationship between the voltage and the value is shown in the following table:...

  • Page 57: Irq Level Setting

    IRQ level. 5.2.3 Dual Interrupt System The PCI controller of PCI-9111 can receive two hardware IRQ sources. However, a PCI controller can generate only one IRQ to PCI bus, the two IRQ sources must be distinguished by ISR of the application software if the two IRQ are all used.

  • Page 58: Interrupt Source Control

    half-full and external interrupt at the same time if your software ISR can distinguish these two events. 5.2.4 Interrupt Source Control There are two bits to control the IRQ sources of INT1 and INT2. Refer to section 4.9 for the details of the bits. In addition, the PCI controller itself can also control the using of the interrupt.

  • Page 59: D/A Conversion

    D/A Conversion The operation of D/A conversion is more simple than A/D operation. You only need to write Digital values into the D/A data registers and the corresponding voltage will be output from the AO1. Refer to section 4.14 for information about the D/A data registers.
