Figure 2 :

Data Format of REMO Output; REF = Reference Time; T0 and T1 = Toggle bits; S0, S1 and

S2 = System address; A, B, C, D, E and F = Command bits.

(a) flashed mode : transmission with 2 toggle bits and 3 address bits, followed by 6 com-

mand bits (pulses are flashed)

(b) modulated mode : transmission with reference time, 1 toggle bit and 3 address bits, fol-

lowed by 6 command bits (pulses are modulated)
