For PWM mode to be controlled by software it is needed to connect an AvaSpec spectrometer to the
AvaLight-HPLED 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.

2.3 Settings for 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 the related software manual 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.
