12. I/R communication circuit • In the ER-A460/A470, infra-red data transmission of the optical communication system is performed. System IRDA ASK REMOTE KEYBOARD Carrier wave 950 nm 900 ∼ 1050 nm 900 ∼ 950 nm Sub-carrier wave (16 times of baud rate clock) 500 kHz±10% 33 ∼ 40 kHz Modulation system "0": HIGH level "1": LOW level Only around the center of the bit cycle in HIGH level, 3/16 of the bit cycle is set HIGH, and the rest is set LOW.
Reception circuit The infra-red signals which was transmitted from the transmission unit through the air is received by the photo diode, and sent through the two-system circuit to the MPCA6, where they are modulated and inputted to the CPU.
