Other remote control systems
designed for use in remote control systems. They
are capable of encoding 16-bit address codes and
8-bit data codes. Each address/data input can be
set to one of the two logic states, 0 and 1.
(K1~K32) and 64 keys (K1~K64), respectively.
When one of the keys is triggered, the programmed
address/data is transmitted together
with the header bits via an IR (38kHz carrier)
transmission medium.
