Before beginning the lab, you need to make
sure that the system is set up correctly. Follow the instructionsbelow to setup the station.
Instructions are included for both the SPEEDY-33 and TI 6711 DSK, follow instructions appropriate to the hardware on your station.

Log on to the computer
Connect a USB cable between the PC USB Port of the SPEEDY-33
(Figure 2 #7) and the USB port of your PC. The SPEEDY-33 is poweredby the USB port. Once you connect the cable, the green Power LED
(Figure 2 #2) on the SPEEDY-33 will light.
Confirm that the Power LED on the SPEEDY-33 is lit.
If the New Hardware Found Wizard starts, follow the
instructions to configure the drivers.
Connect your headphones to the black 3-pronged headphone
booster and connect this booster to the Audio Stereo Output Port
(Figure 2 #4) on the SPEEDY-33. Turn on the headphone volumebooster.
Connect the light gray cable coming out of the computer
(which is the audio output from the computer sound card) to theshort gray male-male adapter cable and connect this, in turn, to
the Audio Stereo Input Port (Figure 2 #3) of the SPEEDY-33. Thesoundcard output (either CD audio or microphone) will be the input
to the DSP board for most of this lab.
Switch the Jumpers on the SPEEDY-33 to the Line position.
Refer to Figure 1 for the location of the Line/Microphone Jumpers(Figure 2 #9).
Ti 6711 dsk setup instructions
Plug the A/C adapter into the DSP board and make sure that
the power LED is lit.
Connect your headphones to the black 3-pronged headphone
booster and connect this booster to the OUT jack on the audiodaughter card attached to the DSP board. Do not use the OUT jack
directly on the DSP board. Turn on the headphone volumebooster.
Connect the light gray cable coming out of the computer
(which is the audio output from the computer sound card) to theshort gray male-male adapter cable and connect this, in turn, to
the IN jack of the audio daughter card. Do not use the IN jackdirectly on the DSP board. The soundcard output (either CD audio or
microphone) will be the input to the DSP board for most of thislab.
Log on to the computer.
Once you log on, a DSK Init window should appear on the task
bar. Click on it to open up the window and then press ENTER asoften as needed to complete the initialization. This configures the
parallel port of the computer to communicate with the DSP board.Note: If you forgot to supply power to the DSP board prior to this
step, the initialization will fail. In which case, you will have tolog off, power up the DSP board, and then log on again and run the
initialization routine again.
Select the EE 453 folder and create a folder within this
folder to store your lab files. Use some descriptive name toidentify your lab group. The path for this folder will be
Desktop\ee 453\<folder name>
Activate Surround Mixer, a program which controls the
input/output operation of the sound card. The Surround Mixercontrol panel is a mixer consisting of numerous volume bars, each
controlling a different aspect of the sound card. The far leftvolume bar controls the master volume. Make sure that the master
volume is set to 100%. The volume bars in the middle control thevarious types of sound sources that the sound card can play (wave
files, microphone input, MIDI input, music CD input, etc). Makesure that the wav/mp3, microphone, and line-in volumes are set to
100%.
Beneath each of the volume bars is a mute box that can be
toggled on/off. When checked, the corresponding sound source isdeactivated. Make sure that all source buttons are muted for
now.
Keep the Surround Mixer open throughout the lab. You will be
selecting various inputs (wave, microphone, and line-in) throughoutthe lab.
When you are finished with each lab, exit LabVIEW, log off the computer, turn off the function generator and the headphone volume booster, and unplug the DSP board from the A/C adapter. Turn in Answered Questions to the TA.
