11. RHYTHM SLEEP WIND MODE
Pressing MODE key in sleep wind mode brings
SC2128C into rhythm sleep wind. In rhythm sleep
wind mode, SC2128C outputs LOW, MIDDLE or
STRONG rhythm wind pattern and automatically
steps down one level every 30 minutes until it
reaches low rhythm wind level. If no off-timer is set,
SC2128C keeps in low rhythm wind output.
Otherwise it restores off state when the off-timer
times out.

12. BUZZER OUTPUT
All valid key pressed except OFF/BUZZ initiates a 150ms
duration 4kHz 50% duty cycle pulse train at OFF/BUZZ pin.
OFF/BUZZ key function as OFF key if pressed when fan is
in any on state. In this case, it does NOT initiate an output
on BUZZ. Note that when OFF/BUZZ outputs the pulse train,
key input is suppressed. That is, pressing OFF/BUZZ key
when the buzzer is buzzing is NOT recognized by SC2128C.
The diagram right shows the buzzer connection.

13. REMOTE CONTROL DECODER
SC2128C is designed to be used together with SC2268 infrared ray remote control encoder. Such combination
allows up to 8 remote control keys – SPEED, MODE, TIMER, LIGHT, SLEEP, SW1, SW2, OFF/BUZZ – to be
built on the remote control handset. 4 bits customer code, b3 ~ b6, is encoded by SC2268 and decoded by
SC2128C in order to avoid remote control contention between devices. With SC2268, b3 is determined by
bonding option; b4, b5 and b6 are determined by connecting respective c4, c5, c6 pin to V
DD
or V
SS
. With
SC2128A, b3 and b6 can be mask programmed upon customer request and with NRE.
The remote control signal coding scheme is fully
compatible with SC2268. Some description follows.
Please refer to specification of SC2268 for details.
When SC2128C receives a remote control signal at
its REMOTE pin, it decodes the received waveform
into consecutive “0” bits and “1” bits. It first
compares the received start word against its
customer code. If and only if the start word matches
the customer code, it then compares for two
consecutive and matched code words. It then
actuates the command according to the code words
table shown later.
