Setup Menu: 1 kHz Enable (DO2) for USB1 platform
Pin 2 of the high density 15 pole Sub-D connector at the AvaSpec can be used to generate an 1 kHz
signal. This signal can be used to control an AvaLight-LED light source in pulsed mode.
Setup Menu: PWM (AvaLight-LED) control for USB2 platform
The AvaLight-LED needs to be attached to AvaSpec-USB2 by connecting an IC-DB26-2 interface cable
between the high density 26 pole Sub-D connectors at the AvaSpec-USB2 and the 15-pole DB
connector of the AvaLight –LED (DO1 – pin11).
The frequency can be set between
500 Hz and 300 kHz, the duty cycle
between 0 and 100%.
If used with a multichannel system,
all channels can have their own
independent PWM setting for both
frequency and duty cycle.
To disable the PWM output, simply
enter 0 under the Duty Cycle.
