Description
This command controls the behavior to a TTL step pulse at the Pulse input
BNC connector. The parameter string can be either RISE or FALL, meaning
triggering occurs on the rising or falling edge of the pulse.
When a pulse arrives at the Pulse BNC input, the platter will rotate either at
the rising or falling edge as defined by this setting. The size of the step is
controlled by the Set StepSize command.
Note: The TTL pulse should be a minimum of 10uS, or longer. The direction
can be controlled by the Set PulseDir command.
