Note: If you are NOT using a procomp amp with NC software, click here to see instructions specific to your system, including the larger metalic NeuroCybernetics amplifier.
Connect Neury to the green "audio out" plug in the sound card in the therapist computer (diagram). Note: If you are using the procomp amplifier, you must have a sound card in your therapist computer to generate the tactile feedback. While many people do connect the bear to the game computer just to hear the beeps, to get the real tactile effect, you must connect to the therapist computer. If you do not have a sound card in the therapist computer, or you are not able to activate the tactile bear, try the troubleshooting tips at the bottom of this page.
... Sounds derived directly from the brainwaves are played to the client through the speaker inside the tactile cushion or animal. (Note that these are separate and different from the loudspeakers connected to the Game computer which provide beeps and music.) In the Tactile mode, the mid-frequency reward band signal is output to the speaker(s) through an external amplifier. This signal frequency is below the hearing range, so although one can hear it because its overtones excite the loudspeaker, the signal is best detected by placing fingers or the body in contact with the Tactile cushion or animal.
In the Audio mode the same signal is made to modulate an 80 Hz carrier wave, which creates much stronger overtones of the brainwave signal, making it more easily audible.
The single-key commands that control this feature are all alphabetic keys, except that ‘+’ and ‘-‘ are used with this as well as with goal and scale changing. If the tactile feature is installed, the commands are shown along with the function key commands, when you press <F1>. When the feature has been enabled, its status and a brief menu appear on the bottom line of the screen. In this discussion, enabled means that the tactile or audio signal will be output, provided other conditions are met, and selected means that commands (alphabetic keys) apply to the selected mode.
If the Tactile feature has been installed, pressing “T” (for tactile) or “A” (for audio) enables that mode of feedback, and also selects that mode for control purposes. You must first start feedback <F5> before enabling the tactile or audio functions. Both modes can be enabled at the same time, but only one can be selected. Sound card-based systems can have only one output channel active at a time (0) although an option exists to swap the function of that output. Pressing “T” selects the tactile mode and unselects audio. It also unselects any goal or scale that had been selected for adjustment. In other words, we are able to adjust scales, goals, tactile and audio feedback, but only one at a time. Selecting any adjustment mode, whether by T, A, <PgUp> or <PgDn>, unselects any other mode. Pressing <Enter> unselects all adjustment modes.

The tactile status and menu line above shows that tactile feedback has been enabled; the output is going to D/A channel 0; the signal is taken from the middle frequency band; and the loudness has been increased to 12. All of this is stated in the left-hand eight characters. The word “Audio” shows that the audio channel has not been enabled. If the therapist now presses “A” the audio channel will also be enabled. By default tactile uses channel 0 and audio uses channel 1. Both use the middle frequency band as the signal source, and both start with a loudness of 4. Note that when audio is selected, tactile is still enabled, but no longer selected. Thus the ‘+’ and ‘-‘ keys affect the loudness of the audio channel.

BetaSMR training only uses the reward signal for output. In Alpha Theta training, any of the three filtered signals can be used as a source for the tactile or audio feedback. If one channel is selected (by pressing “T” or “A”) its source can be switched to the Low or Middle or High frequency band by pressing L, M or H. It seems unlikely that the high frequency source will be wanted, but if you press <F1> you will see that it is provided for.
Three other functions not mentioned in the menu line are shown in the <F1> menu.
T: Tactile
A: Audio (modulated)
U: Unmodulated audio
K: Kill selected chan
L: Low Freq
M: Mid Freq
H: High Freq (bot trace)
X: Swap speakers
“U” uses the signal from the selected band without modulation. This is always the method for the tactile channel but it can be made for the audio channel as well by pressing “U”.
“K” (kill) disables the selected channel. If that channel is enabled (and selected) again (by “T” or “A”) the previous setting for channel, signal source and loudness will be restored. The selected channel may also be disabled by decreasing its loudness to 0; now re-enabling it restores the default values.
If both channels are killed, the tactile menu line at the bottom of the screen will show both channels as disabled.

“X” exchanges audio channels 0 and 1.
1. No sound card
If your therapist computer does not have a sound card, you need to very specifically
find a sound card that supports TRUE sound blaster 16 specs. This is best accomplished
by purchasing an actual sound blaster 16 card, either ISA or PCI. The ISA version
is preferred if your computer is old enough to support it.
2. No sound from the bear - testing the bear
If you don't hear any sound at all from the bear, a great way to test the bear
is to plug him into another sound source that you know works. For example you
can connect the bear to the game computer, and hear the beeps come out of the
bear, you you can even connect him to the headphone jack on your stereo and
listen to your favorite mozart CD through the bear. To do this, follow the connection
diagram using the game computer or other sound source.
3. No sound from the bear - testing the sound card in the therapist computer
If you have tested the bear, and he works fine, then you will want to test the
therapist computer. Exit from the blue dos menu and type the command "trysnd"
this will appear like this:
C:\EEG\EXEC>trysnd
if this command reports "No Adlib" Then you do not have your blaster
line set in the system setup. To create this line, first, install the sound
driver CD that came with your sound card. Install this from windows. If you
do not have this CD, contact your vendor, or purchase a new sound card. If the
sound drivers do not solve the problem in creating the blaster line, try the
command "srun d" at a command prompt.
4. Constant humm with no change in amplitude with the feedback.
You may notice that touching the end of the signal cable to metal will create
a ground hum, which can be mistaken as the normal vibration of a working tactile
bear. Make sure the plug is in all the way.
5. Beeps from the bear
If your bear is beeping and you did not mean to have him beep, make sure you
have connected the bear to the therapist computer, not to the game computer.
