  • Page 20: Digital I/O Lines

    When debounce is not selected (the default configuration), a delay of less than 1 ms occurs. Refer to the KUSB-3160 Getting Started Manual for more information. Outputs are open collectors with a 100 kΩ resistor connected to the internal isolated +5 V.
  • Page 21 Principles of Operation You can specify the digital input lines to read in a single-value digital I/O or continuous operation. You can specify the digital output lines to write to in a single-value digital I/O operation. Refer to page 14 more information on digital I/O operation modes.

  • Page 22: Resolution

    Chapter 2 Resolution Using software, specify the number of digital I/O lines to read or write at once by specifying the resolution as 8, 16, 24, or 32. Table 1 shows the effect of resolution on the number of DIN and DOUT subsystems available for a bank.

  • Page 24 Chapter 2 For example, if you specify a resolution of 8, you can read or write to each digital bank separately by specifying element number 0 to 11. If you specify a resolution of 16, you can read or write to two banks at once by specifying element 0, 2, 4, 6, 8, or 10.

  • Page 25: Interrupts

    Principles of Operation Interrupts The KUSB-3160 module can generate a PCI-bus interrupt when any of the digital input lines corresponding to banks 10 and 11 changes state. This feature is useful when you want to monitor critical signals or when you want to signal the host computer to transfer data to or from the module.

  • Page 26: Operation Modes

    Chapter 2 Operation Modes KUSB-3160 modules support the following digital I/O operation modes: • Single-value operations are the simplest to use but do not allow you to check the interrupt status. Use software to specify the DIN or DOUT subsystem, the resolution, and a gain of 1 (the gain is ignored).
