Board Functions
Relay - NC, C, NO connections.
NC = Normally Closed position of the relay contacts ( Circuit is ON- will open circuit (OFF) when activated )
C = Common connection to relay contacts
NO = Normally Open position of the relay contacts ( Circuit is OFF- will close circuit (ON) when activated )
Green LED Status - Activates when the Relay is powered ON.
JP1 - Relay / Pin Output Jumpers. When this jumper is in place, the board will activate the on-board relay.
The relay is rated at 30 V @ 2Amp. When the jumper is removed, the relay is de-activated and the output pins
next to the jumper may be used as voltage drivers ( 0 Vdc and 4 Vdc @ 10mA). The pins are marked with
Plus (+) and Minus (-) for correct polarity connection. Use caution when connecting to the pins to observe
correct polarity (+ / - )
ON / OFF Power Switch
Turns ON and OFF power to the Wizard - VIII controller board.
When powering the board, a set of remote switch wires can be soldered to these holes for a more permanent
connection.
POWER - Wire Terminal
+ ( Plus ) and - ( Minus ) connections
When powering the board from a non 2.1 mm power connector supply, the power wires can be connected to
these terminals for a more permanent connection. Observe polarity + and - to prevent damaging the board.
Speaker Wire Terminal Block
Connect a small 4 to 32 Ohm - 1 watt speaker to the terminal for on-board sound chip amplification
playback. The on-board VOLUME potentiometer can be adjusted to control the audio output level for the
Speaker Terminal. Note this control does not adjust the Line Output Jack audio signal level.
Line Input Jack
Up to 4 minutes of audio may be stored in the on-board chip. The source for this is the line level signal.
Connect a Mono Audio cable from a sound source into the Line Input Jack. Input sensitivity = 320 MV P-P
for maximum recording volume.
Line Output Jack
The audio output from the sound board may be amplified by an external amplifier, by connecting an audio
cable to the Line Output jack or the two pin header and directly into a remote Audio Amplification System.
Note: The on-board amplifier is automatically disconnected when an audio jack plug is inserted into the Line
Out jack. The line output signal is approximately 2 V P-P at maximum recorded volume.
RECORDING TIMES: The maximum recording time is 4 minutes for the sound chip and 5 minutes for
the Digital / Relay - ON / Off action.
Example
1. Recording An Audio Track
Set the PLAY - REC slide switch to REC (Record) position.
Set the SOUND - RELAY slide switch to SOUND position.
Set the AUTO - ON slide switch to the AUTO position (Off)
Connect one end of an Audio (Mono) Cable to the Line Input jack and the other end to a Audio Source
(Computer sound port, CD Player, Stereo, Etc.)
Start the Audio Source (Computer, CD Player, Stereo, Etc.)
Press and Release the GO button - the Red LED light will turn ON. (Recording sound into chip has
started)
Press and Release the GO button to terminate the recording session when the audio is done - the Red LED
will turn OFF. The Digital / Relay will respond to the Digital button ON-OFF during recording.
NOTE: The sound chip will not playback any sound unless there is a stored relay / digital
recording. If you erase the relay digital recording then the sound chip will not playback sound
until you have re-recorded a relay / digital program routine.
