Install the cDAQ-9189 chassis, connect external power, and verify the installation.

Refer to the cDAQ-9189 front panel diagram while completing the following assembly steps.

  1. Install the application software (if applicable), as described in the installation instructions that accompany your software.
  2. Download the NI-DAQmx driver from ni.com/downloads.

    Package Manager downloads with the driver software to handle the installation. Refer to the Package Manager Manual for more information about installing, removing, and upgrading NI software using Package Manager.

    Note Refer to cDAQ-9189 Driver Support for the earliest NI-DAQmx support version for each cDAQ Ethernet chassis.
  3. Follow the instructions in the installation prompts.

    Windows users may see access and security messages during installation. Accept the prompts to complete the installation.

  4. When the installer completes, select Restart in the dialog box that prompts you to restart, shut down, or restart later.
    If you have problems installing your software, go to ni.com/support and search for the driver name.
  5. (Optional) Mount the cDAQ chassis to a panel, wall, or DIN rail, or attach the desktop mounting kit, as described in the Mounting the cDAQ-9189 section.
  6. Attach a ring lug to a 1.31 mm2 (16 AWG) or larger wire. Connect the ring lug to the chassis ground terminal on the cDAQ chassis using the chassis grounding screw as shown in the following figure. Attach the other end of the wire to the grounding electrode system of your facility. Refer to the Chassis Grounding Screw section for more information about making this connection.
    Note If you use shielded cabling to connect to a C Series module with a plastic connector, you must attach the cable shield to the chassis grounding terminal using 1.31 mm2 (16 AWG) or larger wire. Use shorter wire for better EMC performance.

  7. Make sure that no signals are connected to the C Series module.
  8. Align the C Series module with the cDAQ chassis slot.
  9. Squeeze both C Series module latches, insert the module into the module slot, and press until both latches lock the module in place.
  10. Wire the C Series module as indicated in the C Series module documentation.
    Note Connect I/O cable shields to the chassis grounding screw, shown in the previous figure, unless otherwise specified in the C Series module documentation. Refer to the Chassis Grounding Screw section for more information about making this connection.
  11. Connect one end of the Ethernet cable to an Ethernet port on the chassis, and the other end directly to your computer or any network connection on the same subnet as your computer. Refer to the Ethernet Cabling section for information about the Ethernet cable.
  12. Power the chassis using the included power supply or the included power connector with an external 9 V DC to 30 V DC power source. For information about wiring your external power source to the power connector, refer to the Wiring External Power to the cDAQ Chassis section. The cDAQ chassis requires an external power supply that meets the specifications listed in the specifications document for your cDAQ chassis.
    Note When operating the cDAQ-9189 in hazardous locations, you must use the power connector with an external power supply rated for hazardous locations. The power supply included in the cDAQ-9189 kit is intended only for desktop use. For all other applications use the included 2-position power connector plug and a power supply rated for your application power requirements. Visit ni.com to find hazardous locations-certified power supplies.
    The POWER and STATUS LEDs light. The POWER LED lights as long as power is being supplied to the cDAQ chassis. The STATUS LED turns off after firmware boots. Refer to the cDAQ-9189 LED Indicators section for information about the LEDs on the cDAQ chassis.
