Visual Indicator Controls

The visual indicator control sections allows one to configure the LEDs. The LEDs can be placed in three modes. Off, On and Flash Mode. There are three LED colors; Green, Red and Blue.

Flash mode allows one to select the frequency and duty cycle of the flashing LED.

The prescalar variable divides the main 1.024ms clock to make the LED clock. A prescalar value of 1 will produce the fastest LED clock. The max and min period values show the current max and min periods available given the current prescalar value.

The offset variable allows one to control when the LED starts it's flashing mode. Pressing the sync button will restart all the LEDs in flash with it's corrisponding offset value. You can use this command to synchronies or produce special flash modes.

Audiotory Indicator Controls

The auditory indicator controls allows one to set the frequency, duty cylce and repeat count.

The frequency is entered in Hz. The minimum and maximum frequency are 15.3Hz and 3906.3.

The duty cycle is controled by setting the on and off time. The units are in 50ms.

The repeat value controls the mode of the buzzer. A zero value puts the buzzer is continous buzzing mode. A value of 255 puts the buzzer is a continous duty cycle mode. Any other value will put the buzzer in the duty cycle mode for the number of times selected.

The Start button starts the buzzer and the Stop button stops the buzzer. If you select a finite duty cycle mode the buzzer will stop on it's own after the repeat count supplied has finished.

Button Control

The Button control sections allows one to put the button into different response modes and shows the current state of the button.

AutoClear puts the device in to the auto clear mode. In this mode all LEDs and the buzzer will be turned off when the button is activated.

AutoConfirm puts the device in to the auto confirm mode. In this mode the device sound two quick tones when the button is pressed.

Turns the corresponding light off.


Turns the corresponding light on.


Puts the corresponding light in flash mode.


This is the calculated flash rate in Hertz given the current OnTime, OffTime and PreScalar values.

Flash Rate (Hz) = 1/(1.024ms*PreScalar*(OnTime+OffTime))


This is the current duty cycle of the light ON time. Express in 100%.

Duty (%) = 100 * OnTime/(OnTime+OffTime)


This is the calculated flash rate in seconds given the current OnTime, OffTime and PreScalar values.

Period (Sec) = 1.024ms*PreScalar*(OnTime+OffTime)


This value controls how long the light will stay ON for. The units are 1.024ms*Prescalar Value.


This value controls how long the light will stay OFF for. The units are 1.024ms*Prescalar Value.


This value is the offset or delay value used with the Sync  button. The units are 1.024ms*Prescalar Value.


The Sync button resynchronizes all the current lights that are in flash mode using the Offset values. You can use this button along with the offset values to put the ligths in two a sequenial/chase type mode.


This fields allows one to select a unique USB Visual Indicator. If you only have one devices attached to your computer only one device name will appear.


This value is the frequency of the buzzer is Hz. The buzzer range is 3906.3Hz to 15.3Hz.


This value is the repeat value of the buzzer. A value of zero will set the buzzer in a continuous mode. A value of 255 will set the buzzer is a continuous cycle mode. All other value will sound the buzzer x times.


This value controls the ON time of the buzzer. Units are in 50ms.


This value controls the OFF time of the buzzer. Units are in 50ms.


This button starts the buzzer control with the current frequency, repeat value, ontime and offtime.


This button stops the buzzer.


This is the maximum period permissible given the current Prescalar value.


This is the minimum period permissible given the current Prescalar value.


The is the prescalar value. It's units are in 1.024ms. This value effects all the light is flash mode.


When enabled this check box will automaticly set all the lights to the off state and stop any auditory functions.


This check box represents the button in the USB Visual Indicator. It will show checked when the button is active and non checked when the button is non active.


When enabled this check box will automaticly set sound the buzzer with two confirmation tones.
