Output cycle (external Winddisplay LED)
The telegrams „True Wind“ and „Relative Wind“ are issued every second. With baud rates
less than 4800Bd, it may be impossible to terminate output within one second, owing to
circumstances. The subsequent telegram is started upon complete output of the previous
telegram.
