Output sequence (data format)

The output operation will start when the selected code is found. A burst of pulses, including the latched address and

command codes, is generated at the output REMO as long as a key is pressed. The format of the output pulse train is

given in Figs 2 and 3. The operation is terminated by releasing the key or if more than one key is pressed at the same

time. Once a sequence is started, the transmitted words will always be completed after the key is released.

The toggle bits T0 and T1 are incremented if the key is released for a minimum time tREL (see Fig.4).

The toggle bits remain unchanged within a multiple key-stroke sequence.

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 command bits (pulses are flashed).

(b) modulated mode: transmission with reference time, 1 toggle bit and 3 address bits, followed by 6 command bits (pulses are modulated).
