9.2

Bit coding using two subcarriers

9.3

High data rate

A logic 0 starts with 8 pulses at 423.75 kHz (fC/32) followed by 9 pulses at 484.28 kHz

(fC/28) as shown in Figure 20. For the Fast commands, the x2 mode is not available.

Figure 20.

Logic 0, high data rate, two subcarriers

A logic 1 starts with 9 pulses at 484.28 kHz (fC/28) followed by 8 pulses at 423.75 kHz

(fC/32) as shown in Figure 21. For the Fast commands, the x2 mode is not available.

9.4

Low data rate

A logic 0 starts with 32 pulses at 423.75 kHz (fC/32) followed by 36 pulses at 484.28 kHz

(fC/28) as shown in Figure 22. For the Fast commands, the x2 mode is not available.
