Sequence 2
(Follow-F)
This sequence is the same as Sequence 1, Follow-S, but the LEDs are flashing instead
of showing steady light.
Sequence 3
LatchedAck-F-S
This sequence has a latched function and works in collecting mode. Every LED is
independent of the other LEDs in its operation. At the activation of the input signal,
the indication starts flashing. After acknowledgment the indication disappears if the
signal is not present any more. If the signal is still present after acknowledgment it gets
a steady light.
