The +15 V; -15 V; and +5 V LEDs on the QNET VTOL board are bright green but the External Power LED is not lit.

The encoder does not read 0 when the VTOL body is in the horizontal position.

• Ensure the supplied QNET power supply is connected to the QNET board.

• If the External Power LED still does not light up, the QNET fuse may need to be replaced. Refer to the QNET VTOL User Manual for details.

• Make sure that the VTOL body is in a downward position, resting on the surface of the QNET board before the VI is run.

Additional Components Required

Install LabVIEW and Add-Ons

STEP 2

STEP 3

To complete your QNET VTOL setup, you will also need the following hardware:

Make sure the following versions of LabVIEW™ and required add-ons are installed:

1. LabVIEW™ 2012 or later

2. NI DAQmx 9.5.5 or later

3. NI ELVISmx 4.4 or later

4. LabVIEW™ Control Design and Simulation Module 2012 or later

At least one of the +15V, -15V, or +5 LEDs on the QNET VTOL board are not lit.

• Ensure that the PCI connector on the QNET board is properly connected to the female connector on the NI ELVIS II unit.

• Check that the system power switch, located on the back panel of the NI ELVIS II unit, and the prototyping power switch, situated on the top of the NI ELVIS are ON.

• If one or more of the +15V; -15V; or +5V LEDs is still not lit, then the 15V or +5V fuse(s) on the Protection Board of the NI ELVIS II has been triggered. Similarly, if the External Power LED is still not lit after connecting the QNET VTOL power, the Variable Power Supplies Fuses on the NI ELVIS II Protection Board have been triggered. See the Protection Board Fuses in the NI ELVIS II User Manual.

FClick on the STOP button to stop running the VI.

Click on the white arrow to run the VI.

Make sure the VTOL body is in the downward position, resting on the QNET board.

The charts show the elevation of the VTOL body measured by the encoder, and the propeller motor current command. The charts should

resemble those shown here. If not, consult the troubleshooting section at the end of this guide.

Open the LabVIEW Virtual Instrument (*.vi) found under the Quick Start folder

Select the device name to match your NI ELVIS II device as shown in the

NI Measurement & Automation Explorer in the Device control.

Bring the support arm into the upright position and align the screw holes on the bottom of the support with the four holes indicated on the bottom of the QNET board.

A BMake sure your PC, NI ELVIS II, and QNET board are powered ON.

Open the Quick Start folder from the VTOL folder in the QNET Resources. The QNET Resources are available for download from www.ni.com/qnets.

A B

Remove the four thumbscrews located on the bottom of the VTOL support.

DTighten the four thumb screws to secure the arm to the QNET board.

When assembled, the system should resemble the QNET VTOL shown in Step 1.

C

Slide the PCI connector at the back of the QNET board into the female connector on the NI ELVIS II.

Place the handle on the front of the QNET board over the bracket located on the front of the NI ELVIS II.

Connect the NI ELVIS II power supply to the back panel of the NI ELVIS II.

Use the NI ELVIS II USB cable to connect the NI ELVIS II unit to your computer.
