  • Page 6 It provides 32 analog input channels with a sampling rate up to 100k samples/s, 12-bit resolution and isolation protection of 2500 The PCI-1713 uses a PCI controller to interface the card with the PCI bus. The controller fully implements the PCI bus specification Rev 2.1.

  • Page 7: Chapter 1 General Information

    The PCI-1713 provides optical isolation protection of 2500 V between the inputs and the PC bus to protect the PC and peripherals from damage due to high voltages on the input lines. It is ideal for the situations where budget-conscious users require flexibility, stability and a high level of isolation protection for their data acquisition system.

  • Page 17 Signal Reference Direction Description Name Analog Input Channels 0 through 31. Each channel pair, AI<i, i+1> (i = 0, 2, AI<0…31> Input 4...30), can be configured as either two single-ended inputs or one differential input. Ground. These pins are the reference points for single-ended measurements and the bias current return point for differential measurement.
  • Page 18 A signal source without a local ground is also called a “floating source”. It is fairly simple to connect a single-ended channel to a floating signal source. In this mode, the PCI-1713 card provides a reference ground for external floating signal sources.
  • Page 19 If one side of the signal source is connected to a local ground, the signal source is ground-referenced. The ground of the signal source and the ground of the PCI-1713 will not be at exactly the same voltage, as they are connected through the ground return of the equipment and building wiring.
  • Page 20 AIGND. Figure 3-4 shows a differential channel connection between a floating signal source and an input channel on the PCI-1713 card. In this figure, each side of the floating signal source is connected through a resistor to the AIGND. This connection can reject the common-mode voltage between the signal source and the PCI-1713 card ground.

    In addition to pacer triggering, the PCI-1713 card also allows external triggering for A/D conversions. A low-to-high edge coming from EXT_TRG will trigger an A/D conversion on the PCI-1713 board. Note!: Don't connect any signal to the EXT_TRG pin when the external trigger function is not being used.
  • Page 22 • Keep a reasonable distance between high-voltage (or high-current) lines and signal cables connected to the PCI-1713 card if the cables run parallel, or route signal cables at right angles to high voltage/current cables.

  • Page 24 The PCI-1713 is delivered with an easy-to-use 32-bit DLL driver for user programming under the Windows 98/95/NT operating system. We advise users to program the PCI-1713 using the 32-bit DLL driver provided by Advantech to avoid the complexity of low-level program- ming by register.

When you set the MUX start channel to an analog input channel, AIn ( n = 0, 1, 2, 3,..., 31), the gain code, B/U and S/D written to the register of BASE+2, is for channel n.

  • Page 40 The PCI-1713 uses one Intel 82C54 compatible programmable interval timer/counter chip. This popular 82C54 offers three indepen- dent 16-bit counters, counter 0, counter 1 and counter 2. Counter 0 is not available for users. Counter 1 is cascaded with counter 2 to create a 32-bit timer for the pacer trigger.

  • Page 43 The output will initially be low after you set this mode of operation. After you load the count into the selected count register, the output will remain low and the counter will count. When the counter reaches the terminal count, its output will go high and remain high until you reload it with the mode or a new count value.
  • Page 44 CLK pulse. The count will be inhibited while the GATE input is low. The counter will start counting after the rising edge of the trigger input and will go low for one clock period when the terminal count is reached. The counter is retriggerable. PCI-1713 User's Manual...
  • Page 45 Before you write the initial count to each counter, you must first specify the read/write operation type, operating mode and counter type in the control byte and write the control byte to the control register [BASE + 30(Dec)]. Since the control byte register and all three counter read/write registers have separate addresses and each control byte specifies the counter it applies to (by SC1 and SC0), no instructions on the operat- ing sequence are required.
  • Page 46 Set bits SC1 and SC0 to 1 and CNT = 0. The second method has the advantage of operating several counters at the same time. A subsequent read operation on the selected counter will retrieve the latched value. PCI-1713 User's Manual...
