Impulse channel setup procedure
This procedure enables the master clock to know what time the
slave clocks are displaying and thus calculate the required
number of catch-up pulses. It also ensures that the correct
type of impulses are output. This procedure must be
performed for both channels (if used) on initial
commissioning.
