Right-click an NI 9225, NI 9227, NI 9229, or NI 9239 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 if you want the FPGA I/O Node to return calibrated, fixed-point data from the module in units of volts for the NI 9225/9229/9239 and amps for the NI 9227. The fixed-point data is signed, with a word length of 24 bits and an integer word length of 10 bits for the NI 9225, 5 bits for the NI 9227, 7 bits for the NI 9229, and 5 bits for the NI 9239. 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. The default is Calibrated.
  • 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.
