Each of the 8 channels can operate in one of the following modes:
Mode Description
FREE RUN The channel delivers pulses continuously according to the
programmed duration and interval times. The channel is
independent of the other channels.
TRAIN Following a trigger, the channel delivers a train of pulses
according to the programmed duration and interval times. The
number of pulses per train is set by ‘M’.

according to the programmed delay and duration times.

and off.
