2.3.1 TRANSMISSION IMPULSE DURATION (RADIO POWER)
To increase the reliability of the radio transmission, the data bundles of the photocell impulses are
transferred repeatedly for a set period of 1.2 seconds. This allows to have redundant information when losing
some data bundles and to rebuild the event with absolute precision.
If between two impulses (e.g. start photocell and stop photocell) more than 1.2 seconds elapse, there are of
course no problems whatsoever.
Even if the difference is smaller, the second impulse will still be detected, as it will always have a longer "tail"
than the first one.
