  • Page 10: Wiring Power To The Chassis

    Info Code earthground Wiring Power to the Chassis The NI 9155 requires an external power supply that meets the specifications in the Power Requirements section. The NI 9155 filters and regulates the supplied power and provides power for all of the I/O modules.
  • Page 11 Optionally, you can connect the positive lead of another power supply to the other V terminal and the negative lead to one of the C terminals. Install the COMBICON connector on the front panel of the NI 9155. Caution To ensure the specified EMC performance, do not connect the power input to a DC mains supply or to any supply requiring a connecting cable longer than 3 m (10 ft).
  • Page 12 Loads the FPGA bit stream from flash memory to the FPGA when the chassis powers on. If you want the NI 9155 to autoload and run a VI at powerup, you must also configure the VI to autoload before you compile it. For more information about autoloading VIs, refer to LabVIEW FPGA Module Help.
