I/O connector
For PWM mode to be controlled by software it is needed to connect an AvaSpec spectrometer to the
AvaLight-LED with the interface cable IC-DB26-2. Now it is possible to control the output operation
mode by software (AvaSoft).
The signals on the I/O connector are described below.

Settings for the PWM Mode
When the light source is used in combination with an AvaSpec spectrometer, interface cable IC-
DB26-2 and AvaSoft, the optical output can be changed by using the PWM function in AvaSoft.
See appendix A for how to set the PWM signal in AvaSoft.
The PWM can be set in a range from 500 Hz – 300 KHz with a 0 – 100% duty cycle.
