Sequence 2 (Follow-F)
SEMOD56072-47 v2
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
SEMOD56072-50 v2
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.
