Right-click an NI 9225/NI 9227/NI 9229/NI 9238/NI 9239/NI 9246/NI 9247 C Series module in the Project Explorer window and select Properties from the shortcut menu to display this dialog box.

Use this dialog box to configure a C Series module.

This dialog box includes the following components:

  • Name—Specifies the name of the C Series module, which appears in the Project Explorer window. LabVIEW assigns a default name to the module based on the slot number. You can use this field to give the module a descriptive name.
  • Module Type—Specifies the type of C Series module. You cannot change this option.
  • Location—Specifies a slot in the chassis for the C Series module.
  • Calibration Mode—Sets the calibration mode for the C Series module.
    • Select Calibrated, which is the default, if you want the FPGA I/O Node to return calibrated, signed, fixed-point data from the module. The following table describes the units and integer word length of the returned data:

      Module Units Word Length (bits) Integer Word Length (bits)
      NI 9225 V 24 10
      NI 9227 A 24 5
      NI 9229 V 24 7
      NI 9238 V 24 1
      NI 9239 V 24 5
      NI 9246 A 24 7
      NI 9247 A 24 9
    • Select Raw if you want the FPGA I/O Node to return uncalibrated, binary data from the module. If you select Raw, you must convert and calibrate the analog input values in the host VI.
  • Master Timebase Source—Specifies the master timebase source that the module uses.
  • Export Onboard Clock—Place a checkmark in this checkbox if you want to make this module accessible as a master timebase source to other modules.
  • Data Rate—Specifies the rate at which the module acquires data.
