Inputs/Outputs

  • ci32.png bus

    bus refers to the GPIB bus number. If you have only one GPIB interface in your computer, the default bus number is 0.

    Refer to the software installation instructions included with the GPIB controller for additional GPIB interfaces.

  • ci16.png mode

    mode describes how to signal the end of the data to the Listener.

    This input accepts the following values.

    0Do nothing to mark the end of the transfer (default).
    1Send NL (linefeed) with EOI after the data bytes.
    2Send EOI with the last data byte in the string.
  • cstr.png data string

    data string contains the data bytes the function sends over the GPIB.

  • cerrcodeclst.png error in

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • i1dbool.png status

    status is a Boolean array in which each bit describes a state of the GPIB Controller.

    If an error occurs, the function sets bit 15. GPIB error is valid only if bit 15 of status is set.

    The following table shows the numeric value and symbolic status of each bit in status. This table also includes a description of each bit.
